PSP has 2, 333 MHz processors. Not one

http://psp.ign.com/articles/513/513175p1.html PSP INITIAL TECHNICAL SPECIFICATIONS

PSP CPU CORE MIPS R4000 32bit Core 128bit Bus 1 - 333MHz @ 1.2V Main Memory :8MB(eDRAM) (**Changed to 32MB, 4MB embedded in May 2004) Bus Bandwidth :2.6GB/sec I-Cache, D-Cache FPU, VFPU (Vector Unit) @ 2.6GFlops 3D-CG Extended Instructions

PSP Media Engine MIPS R4000 32bit Core 128bit Bus 1 - 333MHz @ 1.2V Sub Memory:2MB(eDRAM) @ 2.6GB/sec I-Cache, D-Cache 90nm CMOS

http://en.wikipedia.org/wiki/PlayStation_Portable_hardware The PSP's main microprocessor is a multifunction device named "Allegrex" that includes a 32-bit MIPS32 R4k-based CPU (Little Endian), a Floating Point Unit, and a Vector Floating Point Unit. Additionally, there is a processor block known as "Media Engine" that contains another 32-bit MIPS32 R4k-base CPU, hardware for multimedia decoding (such as H.264), and a programmable DSP dubbed "Virtual Mobile Engine". The secondary CPU present in the Media Engine is functionally equivalent to the primary CPU save for a lack of a VPU

http://www.psp-programming.com/tutorials/c/lesson05-2.htm So now that we have it all set up, we get to the meat of the program, the main() function. int main(void) {

         scePowerSetClockFrequency(333, 333, 166);

This is the line that sets the clock frequency (as should be evident from the function name). You may be wondering why there are three parameters, though. I mean, there's only one processor, right? Wrong. The PSP actually has three processors. The first sets the CPU (the main processor); this is what most of your programs will be running on. The second parameter is the Media Engine. Last I checked, you could only run MIPS Assembly code on this processor. The Media Engine also runs at 333 MHz. The third parameter controls the Graphics Core. This is what people mean when they talk about using the "GPU." The GPU runs at 166 MHz. —Preceding unsigned comment added by 24.36.17.82 (talk) 07:52, 24 February 2009 (UTC)

Rechargeable battery?

does the PSP have a rechargeable battery? I figure we ought to state whether or not in the article (plus I'm planning on getting a PSP, and I would personally like to know, anyway) —Preceding unsigned comment added by 64.218.92.100 (talk) 23:02, 5 December 2007 (UTC)

Of course it has a rechargeable battery. Pretty much all high-tech handheld electronics have rechargeable batteries nowadays. Farslayer (talk) 07:14, 19 January 2008 (UTC)

Yes and perhaps you should also know that it lasts up to 13 hours I think depending on the brightness level and sound and what type of media you are using. But most of the time I find the battery to be very reliable. —Preceding unsigned comment added by Camilo101 (talk • contribs) 17:47, 15 February 2008 (UTC)

PSP sales are out of date

Sales data needs to be updated to correct numbers, like DS and wii have. Units sold says its only 14.49 million, and units shipped is 25.39 million. Anyone with a brain can see how stupid that is. The source of that 14.49 million is from a chart on sonys corp site, and it says, that figure was calculated from (starting at) 2006 onwards to Q2 07. With the reasonable sales of the lite model, im sure both shipped and sold would be over 30 million by now. I guess we will probably have to wait till sony releases numbers in march 08? The best for sold numbers is vgchartz, but they are pretty poor for sales numbers, especially for the PAL region.—Preceding unsigned comment added by 58.105.158.241 (talk • contribs)

Slight wording change please

(Under Games) The sentence "Currently, the only two official ways to access this feature..." should be changed to "Currently, there are two official ways to access this feature..."

Saying "the only two" impresses upon the reader that there should be more, which is an extension of opinion.

Screen

There's no mention of the spec of the screen; what size it is, that it's LCD, what kind of backlight it uses, how the Japanese version differs, ghosting and/or blurring.

I came to the article hoping to find what size the screen was to compare other gadgets to it, but to no avail.

Here's a source of info on the specification, including the screen: http://www.psp-zone.co.uk/PSP-Technical-Spec/PSP-Specification.html 84.12.21.141 (talk) 00:10, 9 January 2008 (UTC)

I'm pretty sure the screen's like 4 and a half inches, and in 480p? or i? There's not any blurring or ghosting I've seen. The important thing to know is it's a better screen than the DS, and that it's also one of the biggest screens I've seen in handheld devices like that. —Preceding unsigned comment added by Camilo101 (talk • contribs) 17:45, 15 February 2008 (UTC)

its not in 480p or i, infact a device like this would never use an interlaced picture, the screen is 480x272, i have a japanese launch machine thats horibly ghosty. —Preceding unsigned comment added by 81.97.202.197 (talk) 02:18, 22 February 2008 (UTC)

CES

A few announcements were made at CES '08 by Sony:

• Skype voice communication coming to the psp
• Camera coming to the U.S.
• GPS coming to the U.S.
• Keyboard coming to the U.S.
• Able to download Blu-ray movies that are in your PS3 to your PSP memory stick to play. Saves more power than if you were playing a UMD movie.

I found all of these at The Feed.--Playstationdude (talk) 20:34, 9 January 2008 (UTC)

Here are the "permalink" links to those articles: http://www.g4tv.com/thefeed/blog/post/681975/CES_2008_PS3_Puts_BluRay_Movies_on_PSP.html http://www.g4tv.com/thefeed/blog/post/681984/CES_2008_PSP_Gets_Awesomer.html http://www.g4tv.com/thefeed/blog/post/681851/PSP_To_Get_Skype_Support.html 85.211.74.214 (talk) 07:20, 12 January 2008 (UTC)

More about the Blu-ray to PSP news; it actually contradicts what G4TV said; G4TV said that the videos would be converted by the PS3; CVG says: "Select Blu-ray films due for released in 2008 will come with a second PSP-formatted version of the film on the same disc." http://www.computerandvideogames.com/article.php?id=178884 85.211.74.214 (talk) 07:34, 12 January 2008 (UTC)

The Skype implementation is only for the PSP Slim and Light, cause the original has a lower amount of "system memory" or "main memory" (is that RAM or firmware memory?)

Quote:

Following a system update in late January, the Skype icon will be added to the PSP's XMB in the Network section. However, because the original PSP-1000 model only has 32MB of system memory, as opposed to the PSP-2000's (PSP Slim and Light) 64MB, the original PSP will not receive this Skype compatibility unfortunately. As Nick Sharples, SCEE's Director of Corporate Communications, explains to Three Speech: "Although PSP-1000 and PSP-2000 are identical in basic functions, there are differences in hardware specifications to some extent and, for that reason, PSP-2000 may differ in features from PSP-1000. We had studied the possibility of supporting Skype with PSP-1000 but had to give it up because of the smaller size of main memory on PSP-1000 series."

current - The unit measures 170 mm (6.7inches) in length, 74 mm (2.9 inches) in width, and 23mm

altered - The unit measures 170 mm (6.7inches) in length, 74 mm (2.9 inches) in width, and 23mm (0.9 inches) in height.

also, there seems to be no closing bracket for the first one opened.

PSP selling for a loss?

Might add to the article as well Kamuixtv (talk) 13:31, 23 February 2008 (UTC)

I don't think it is, unless you have a source that says otherwise.--WhereAmI (talk) 05:45, 26 February 2008 (UTC)

I'm sure they took a loss at launch just like every other Playstation product, but by the launch of the slim those costs were down significantly especially with the new PSP-2000 slim model. The memory cards alone have plummeted in value/cost, I remember when the PSP launched a 1GB Pro Duo was about $100 now you can find 4GB Pro Duos for under $45, Sony announced 16GB Pro Duo Memory cards at CES 08' (they will be cheap in 1-2 years). —Preceding unsigned comment added by DevonTheDude (talk • contribs) 03:36, 8 April 2008 (UTC)

selling for al loss is a common strategy in the console market, because the profit is made form licencing fees for the games. --MrBurns (talk) 04:47, 12 November 2008 (UTC)

God of War: Chains of Olympus and Final Fantasy 7: Crisis Core are likely to be the next two best selling games, especially with the Kratos PSP coming out in June.

Video Playback Resolution

Currently the section "Multimedia playback" states: "As of firmware update version 3.30, H.264/MPEG-4 AVC Main Profile video files of the following sizes can be played: 720×480, 352×480, and 480×272." Now, maybe I've greatly screwed something up, but a) I've tried encoding in every one of those resolutions and the PSP will not read the file despite having the most current firmware, and b) every other piece of information I find on the internet states that there is a resolution cap of 76800 pixels. 368x208 has never failed for me. And the picture on the right which claims to be at full resolution doesn't prove anything. 24.71.87.48 (talk) 09:44, 11 March 2008 (UTC)AceOfShades

I'd like some more information on this to be added to the main article. I know for sure it plays 320x240 resolution since I use Tunebite to convert all my videos, and it has three resolutions it lists for PSP. The highest is 640x248 but I haven't got this to work. Does anyone know the actual pixel dimensions of the screen? 65.185.191.27 (talk) 04:05, 22 April 2009 (UTC)

Regarding the safety issues

I believe that the explosion from the 12 year old's battery was because he was using a third party battery, which are unsupported by Sony.

Sony's official policy in reguards to homebrew apps?

Surely Sony must give some kind of reason or justification for this bricking business and so forth. Nintendo has a page like that about emulation. Where's Sony's? --70.252.143.22 (talk) 18:57, 30 April 2008 (UTC)

You mean that bit on how PS3 games can be played via remote on the PSP? Or how you can download PSX Games to be stored in the PSP via the PS3 as well? The PSP has PSX Emulation according to such information. But I guess that's not official because SCEA's website doesn't have that info. If you mean all those cutom firmwares, then there's your reason. Sony doesn't like custom firmwares =/ (You also need a fat PSP to apply to, then transfer the data to a slim one anyway, now that's what I call roundabout.) 66.168.19.135 (talk) 03:11, 23 June 2008 (UTC)

Sony's position is that hacking your PSP to run homebrew apps violates your warranty.[1]--221.143.25.19 (talk) 05:48, 21 July 2008 (UTC)

I believe the main article mentions this. They don't like custom firmware because it allows for emulation and piracy of games. You can download certain PSX games now through the Playstation Store to play on PSP, though I'm not sure if it is through emulation or whether the games have been ported. 65.185.191.27 (talk) 04:08, 22 April 2009 (UTC)

Games Graphics

is it high graphic games or like play station 1 ? —Preceding unsigned comment added by 77.94.38.150 (talk) 19:52, 3 May 2008 (UTC)

Both. Emulation of PSX games is also possible (I hope the article mentions it). Farslayer (talk) 07:17, 7 June 2008 (UTC)

According to Crisis Core Graphics and Tales of the World, it's also capable of some PS2 graphical rendering, not sure about PS2 emulation though. 66.168.19.135 (talk) 03:13, 23 June 2008 (UTC)

For insight here's a Comparison on Dreamcast vs PSP- its a boosted up psone. The lack of AA and bumpmapping textures make it alittle less powerful than Dreamcast (art design makes up for that) but it can play psone, and early shareware era PC games (which dc does better of course). It depends on what type of graphics you like. FTW look at soul calibur on DC, then mk on psp. Ps2 is actually like the psp with lots more polys and jaggies (No AA vertex shading no bumpmapping vector shading substituted equivalent to tnt 2 in HD/monitor display - ugly graphics). Ps2 is a more fair comparison. Its MIPS is 150 and cpu 300+4videoram+32ram while dc is 100@200+8videoram+16ram (open environments vs faster shinier graphics). Back to psp. So in a small screen, psp is worst then ps2 then dreamcast/gamecube. Basically Im trying to say PSP specs look better on paper. But when the processor takes up battery life and onscreen +heavy OS use it degrades performance on a portable it effects the graphics power. Also consider the fact that its multitasking texturing memory capabilities are well, not there (2mb). Its not a design flaw just a way to balance hardware on psp. Portables dont consider AA and bumpmapping because the screen is too small. Diff. playingfield. PSP may have better draw distances and poly counts but well it wont. Its all for realtime rendering. No Competition. Sony uses the same gimic for ps2 which is movies make the game. and who knows prob it does. As for game designs thats totally up to the developers. More budget bigger the game. Memory as big as Cds still are used on Xbox 360/Ps3 games. Which is a whole knew ballpark.

Sales as of June 2008

I did some quick searching and right now it will be difficult to correct the sales data. Part of the problem is that Sony changed their reporting on this from unit shipments to units sold. Here's what I could confirm:

as of 3/31/2007 Sony shipped 25M units
http://www.sony.net/SonyInfo/IR/financial/ar/2007/qfhh7c00000d7pmp-att/SonyAR07-E.pdf

For the Year ending 3/31/2008 there were 13.89 M units sold
For the year ending 3/31/2007 there 9.53M units sold http://www.sony.net/SonyInfo/IR/financial/fr/07q4_sony.pdf

The had the following Unit shipments: FY07 8.36 M FY06 14.06 FY05 2.97M http://www.sony.net/SonyInfo/IR/financial/fr/qfhh7c000000kjva-att/03q4_sony.pdf http://www.sony.net/SonyInfo/IR/financial/fr/04q4_sony.pdf http://www.sony.net/SonyInfo/IR/financial/fr/05q4_sony.pdf http://www.sony.net/SonyInfo/IR/financial/fr/06q4_sony.pdf So until Sony or some third party source publishes some better numbers I'm going to leave the article as-is for now since those number at least both have sources referenced, even if they are a little out of sync.

PSP Ready Websites...

It's a bit hard to make your website ready for PSP, since many sites claim that PSP is running Netscape Navigator 4.0 or something. A simple appName test for "PSP (Playstation Portable) Internet Browser" works, but then you have to jump hoops. So I'm going out on a line here and asking: Is it notable to note that to make a PSP Enabled website, you have to have your margins lower than 480x272? Because I tried it and I had to shrink down my encompassing DIV by a lot (down to 458) to make it remotely good looking, since the browser cuts off a portion of the right side (Firefox does this too when dealing with percentages) Note also the very small font sizes, these look bigger on the PSP of course.

Wording doesn't work that well

"The PSP has faced stiff competition from the Nintendo DS, but remains the second most successful handheld console of its generation.[21]"

According to Wikipedia, the only consoles in the generation are PSP and DS. So "remaining the second most successful handheld console of its generation" isn't exactly a good thing, it means that it's also the worst, yet the wording makes out it is a good thing. If, of course, you are including Gizmondo and GP2X etc., could they be listed in the page that lists the handheld consoles of this generation? LuGiADude (talk) 10:35, 18 July 2008 (UTC)

Well, it had read like this for a while: Although the PSP has faced very stiff competition from the Nintendo DS, it has been by far the most successful handheld console not manufactured by Nintendo. However, sometime try and verify that statement... For all practicle purposes, it's totally impossible. So we decided to have it how it is currently. Hope that answers your question.

Also, the Gizmondo, etc. are listed in History of video game consoles (seventh generation).

Shouldn't the PSP 3000 section be in the slim and lite article? Tut74749 (talk) 19:46, 21 August 2008 (UTC)

No, as the PSP-3000 is a seperate series from the Slim and Lite, which is part of the PSP-2000 series. It is essentially the successor to the slim and lite. KhalfaniKhaldun 19:58, 21 August 2008 (UTC)

The difference is not that great. There wouldn't be much to cover in a separate article, and it would likely be a permanent stub. The SCPH-90000 series is technically separate from the SCPH-70000 series as well, but was not broken off from coverage of the slimline PS2. Dancter (talk) 20:30, 21 August 2008 (UTC)

PSP-3000 merger

Someone suggested that the PSP-3000 article be merged into this one. They didn't start a discussion article stating their reasoning, though, so I'm going to go ahead and start it and state that I am against the proposed merger. As the Slim and Lite (2000) series has its own article, the 3000 series will be sufficient enough to be its own article as well. It was just officially announced this week, and is set for a European release in mid-October, so we can definitely expect to see more details available to fill that article being released soon enough, and as such merging into this one and then turning around and recreating the 3000-series article would be a waste of time. KhalfaniKhaldun 20:22, 21 August 2008 (UTC)

Answer: Yes you need Wifi, the PSP connects fine to any WLan, but I don't know of any other way to connect. Afaik there is no PSP Lan cable.

Webbrowser compatibility

Well in the webbrowser section you get the impression the PSP webbrowser would work with older Flash version 6 files, but due to the vbery limited memory you cant view like 80% of the content. Downloading even large files to a memory stick works very well, but watching flash video never nworked, i tried so many websites without success. Also simple flash games or animations didnt load most of the time or it was just impossible to navigate these. The webbrowser is really nice and fun to use, but forget anything with flash. Some simple navigations and advertising banners work fine, but thats about it. Don't make people expect too much of this flash implementation, it totally lacks the ram. —Preceding unsigned comment added by 87.189.251.94 (talk) 19:53, 15 December 2008 (UTC)

The article claims that the MIPS R4000 is a 32-bit microprocessor. I find that to be a bit suspect as the fact that the R4000 is a 64-bit microprocessor is well established, since the early 1990s.

Consider the "The Mips R4000 processor", which appeared in the IEEE Micro, April 1992. The abstract states: "The R4000, a highly integrated, 64-b RISC microprocessor...". Also consider the "MIPS R4000 Microprocessor User's Manual", which has plenty to say about the 64-bit-ness of the R4000. The R4000 product overview (there should be copy somewhere, maybe at SGI) also supports this.

I cannot recall any authorative source claiming the R4000 to be 32-bit. The infobox in the article claims that the microprocessor is "R4000-based, but the text does not.

Is there a possibility that the R4000 (which implements MIPS III, a 64-bit instruction set architecture) is being confused with the MIPS32 4K Family (which implements MIPS32, as the name suggests, a 32-bit instruction set architecture)? A quick Google search has some results supporting the MIPS32 4K instead of the R4000. Rilak (talk) 08:03, 8 January 2009 (UTC)

Hmmm...I'm unfamiliar with the CPU but this article from CNET [3] states "In the PSP, the core microprocessor unit--which essentially runs the handheld and manages the integrated chip cores--is based on the MIPS R4000 chip design, Okabe said. Both the PlayStation 2 and Sony's Qiro robot are based around MIPS processors, which are derived from chip designs created originally for Silicon Graphics Inc. servers." These articles [4] and [5] both say 32-bit. A Quest For Knowledge (talk) 23:33, 27 January 2009 (UTC)

So which is it? It can't be R4000 and 32-bit, as R4000 is a 64-bit ISA. Maybe the R4000 statement was a typo and they really meant R3000? Or maybe the chip uses the same layout and design as the R4000 but with a different 32-bit ISA. KhalfaniKhaldun 07:12, 28 January 2009 (UTC)

I am certain that "R4000" in this context is a corruption of "R4K", since it is easy to confuse R4K with R4000. But this is original research, which is not permitted. The question is, What do we do about it? Wikipedia's policy is to demand verifiability, not the truth. Rilak (talk) 11:42, 5 February 2009 (UTC)

I did some more research and found an IGN article "The Evolution Of The PSP" dated 29 August 2008 that states, "The PSP's primary media processing block comes from a dedicated 32-bit MIPS32 R4k-based CPU, similar to that which powers the primary operating system." (Emphasis mine). Does this statement imply that the CPU is based on the MIPS32 4K? I am not sure what IGN is referring to here. Rilak (talk) 07:30, 6 February 2009 (UTC)

I think the confusion arises because there's a degree of slackness regarding what "R4000" really means. Super-strictly R4000 was a specific microprocessor made by MIPS, and sold for the workstation and server market. Plainly PSP doesn't have one of those (they weren't made that much, and haven't been at all for years). Rather it's a roughly R4000 IP block, but that doesn't mean it's a functional clone of the R4000 microprocessor you'd find in and old SGI workstation. I've (regrettably too much) experience of development for a number of MIPS licenced products (most notably the R3000-based Philips "Dino" microprocessor. When they licence the microarchitecture block they're quite liberal about what you can and can't include, and a lot of embedded MIPS blocks emit or simplify things that don't make sense in the embedded space. Dino, for example, had a radically simplified TLB and emitted CP1 (the floating-point coprocessor) altogether (together with doing vexing things with the cache architecture and fixating the kernel space chip-select mapping). So don't be confused when something that claims to be "R4000 based" doesn't do all the things a "real" R4000 does. Now it's really a great oversimplification to say "R4000 is a 64 bit architecture" - as MIPS R4000 Microprocessor User’s Manual (2nd ed) by Joe Heinrich (of MIPS) notes, R4000 can operate (in supervisor mode) in either 32 or 64 bit mode; depending on a bit you set (I think in CP0). What they've done is make a 32-bit only version of the R4000 architecture (again with other stuff stripped and simplified) - MIPS themselves describe the block thus: "The MIPS32 architecture is a superset of the previous MIPS I™ and MIPS II™ Instruction Set Architectures (ISA) and incorporates powerful new instructions, specifically for embedded applications, as well as proven memory management and privileged mode control mechanisms previously found only in 64-bit R4000™ and R5000® MIPS® processors. By incorporating powerful new features, standardizing privileged mode instructions, and supporting past ISAs, the MIPS32 architecture provides a solid high-performance foundation for all future 32-bit MIPS-Based development." (ref). In fact, it seems the CPU (which Sony call "Allegrex") has some media-smart stuff added as well. Incidentally the PSPdev folks (the PSP homebrew community) confirm it's in 32-bit here. So really an accurate description would be "Allegrex, a Sony custom design based on a LSI Logic's R4010 32-bit MIPS-32 microprocessor". 87.112.81.29 (talk) 18:02, 13 February 2009 (UTC)

Thanks for the clarifications. I agree that the description should be revised. Also, I am interested to where you got the information for this, "Allegrex, a Sony custom design based on a LSI Logic's R4010 32-bit MIPS-32 microprocessor." (Because if it is going to be used, it needs a citation.)

Just to reiterate, I initiated this discussion because the article text (not infobox) claims that the MIPS R4000 is a 32-bit MPU - "...MIPS R4000 (32-bit) CPU...". There was no mention (in the article text) of it being a derivative or similar, so the article was stating that the R4000 is a 32-bit MPU, which, for reasons previously stated, is wrong. I am aware that the R4000 is capable of operating in 32-bit mode, and if I understand correctly, it can also execute 32-bit code in 64-bit mode, but for convenience, it is not described as such per general usage.

Update?!

The worldwide sales for the psp is as of 20th August 2008, unless it has been discounied since, that should be updated. mcjakeqcool Mcjakeqcool (talk) 17:02, 2 February 2009 (UTC)

No joy? Well If anyone has a answer, give us a bell asap. mcjakeqcool Mcjakeqcool (talk) 15:32, 11 February 2009 (UTC)

Sales Information Synchronization Issue

The sales numbers given in the article's infobox don't match up with what's available in the Sales section of the article. (Psychoneko (talk) 10:29, 14 March 2009 (UTC))

Someone synchronized the two sales numbers, but the citation for the PSP sales clearly does not match the article. The cited article's title says something about the PSP hitting 50 million sales, but the article says 77 million. What's going on? 75.61.141.116 (talk) 06:39, 17 March 2009 (UTC)

Ah! My Goddess!

In season one of AH! My Goddess episode number #25 , Urd plays a game console called POP that bears an almost identical appearance to the PSP, the game console belonged to a kid named Shohei Yoshida in that episode of the Anime.

The PSP was most likely renamed to avoid law suits, this is often done in manga and anime with items such as tv brands, soft drinks, battries etc. The name is most often an offshoot or corruption of the true or orginal name/brand/model/company etc. ~ Awar (talk) 13:07, 1 April 2009 (UTC)

There really is a game console called the POPstation. It is a poor copy of the PSP that's produced in China. - Wysprgr2005 (talk) 18:12, 9 April 2009 (UTC)

PSP Go!

Is this just speculation, or is it notable?[6] Shaq4evr (talk) 01:46, 21 May 2009 (UTC)

Leaked info out today makes this look ever more likely [7]. 16GB of onboard flash and bluetooth support added and a new slide out control panel is noted in the video on the page (see previous link). Official confirmation expected at forthcoming E3 event. --86.145.22.130 (talk) 17:06, 30 May 2009 (UTC)
