Untitled section[edit]

Are CPLDs actually used for bootstrapping FPGAs? I'd thought that was almost exclusively done using external serial PROMs and dedicated bootstrap hardware on the FPGAs (and via on-board microprocessor for the few widgets built to be in-flight reconfigurable). --Christopher Thomas 04:33, 11 Apr 2005 (UTC)

  • Yes, I've done both. Using the dedicated FPGA bootstrap hardware and an FPGA-vendor EEPROM works, but it can complicate field upgrading. My newer products use a CPLD to feed the FPGA configuration from a flash. Overall it is cheaper, as I can use the flash for other purposes as well. N Norder 16:37, 16 November 2006 (UTC)

sum of products versus disjunctive normal form[edit]

I notice that sum-of-products is directed to disjunctive normal form. While disjunctive normal form is a boolean sum (or) of a boolean product (and), I would not consider them synonymous; rather sum-of-products expressions is a category which disjunctive normal form forms an example of. In any case, perhaps someone who knows the proper Wikipedia conventions for linking similar and/or synonymous topics could clean this up? mjscud 18:42, July 21, 2005 (UTC)

I honestly don't know what either term means, but I'd love to learn, unforunately, I have to concur, the misleading way the articles are linked up, seems to me that the information is just plain missing. Very dissapointing. BrainSlugs83 (talk) 08:55, 26 January 2012 (UTC)

Notable suppliers[edit]

A section called "Market Leaders" was added by 204.245.209.24 (talk · contribs). I've changed its name to something a bit less advertising-like, and added additional entries, but it would really help if someone familiar with all of the comanies involved could expand the section to be more like Field-programmable_gate_array#Some_FPGA_manufacturers_and_their_specialties. --Christopher Thomas 05:49, 10 January 2006 (UTC)

Macro Cell[edit]

I miss a logical block descrition of a macro cell on this page, so I can draw lines between the differences of a fpgas logic block/cell and cplds cell structure. —Preceding unsigned comment added by 90.185.223.244 (talk) 11:35, 5 September 2007 (UTC)

External link[edit]

Hello, I'm working for the So-logic company, located in Vienna, Austria, www.so-logic.net. We have developed the FPGA Database application, www.so-logic.net/en/fpga/table/producers. It is the directory of all FPGA families that have ever existed on the market. It is free of charge and available to everyone. We would like to add the link to our database in the Wikipedia external links on this page. We didn't want to do it before discussing it with you. Thank you for your time. --Maja Gordic (talk) 14:57, 6 April 2010 (UTC)

I don't think the link should be added. It is not our practice to add links to vendor sites or lists of vendors. See WP:EL for more details on what should and should not be linked. - MrOllie (talk) 15:10, 6 April 2010 (UTC)
Notice that he's actually offering information that may be useful for the FPGA article, if they actually publish a free database of every FPGA ever made why not use it as a source in the FPGA article? BrainSlugs83 (talk) 08:53, 26 January 2012 (UTC)
