Rockchip (Fuzhou Rockchip Electronics Co., Ltd.) is a fabless semiconductor company based Fuzhou, People's Republic of China. They design SoCs using licensed SIP cores from other companies. Due to their evolution from the MP3/MP4 player market most Rockchip SoCs feature advanced media decoding logic but lack integrated cellular radio basebands.

Rockchip is a leading supplier of SoC solutions to Chinese white-box tablet manufacturers[4][5][6] as well as supplying top-tier OEMs such as Asus,[7][8] HP[9] and Toshiba.[10][11]

Rockchip is an ARM licensee and uses the ARM architecture for the majority of its projects.[12]

However, on 27 May 2014 Intel announced that it has entered into a strategic agreement with Rockchip to accelerate the adoption of the Intel architecture and Intel's communication-based solutions for a range of entry-level tablets targeted at the worldwide market.[3] Under the terms of the agreement, the two companies will deliver an Intel-branded mobile SoC platform. The quad-core platform will be based on an Intel Atom processor core integrated with Intel's 3G modem technology, and is expected to be available in the first half of 2015.[3] Both Intel and Rockchip will sell the new part to OEMs and ODMs, primarily into each company's existing customer base.[3]

Markets and competition[edit]

In the market for SoC solutions for tablets, Rockchip faces competition from Allwinner Technology,[13] MediaTek,[5] Intel,[14] Actions Semiconductor,[15] Spreadtrum,[16] Samsung Semiconductor, Qualcomm, Broadcom, VIA Technologies[13] and Amlogic.[13]

After establishing a leading position early in the developing Chinese tablet SoC market, in 2012 it faced a challenge by Allwinner.[2] In 2012, Rockchip shipped 10.5 million tablet processors, compared to 27.5 million for Allwinner.[13]

However, Rockchip subsequently improved its competitive position. For Q3 2013, Rockchip was forecasted to ship 6 million tablet-use application processors in China, compared to 7 million for Allwinner who mainly shipped single-core solutions.[17] Rockchip was reported to be the number one supplier of tablet-use application processors in China in Q4 2013, Q1 2014 and Q2 2014.[4][6]

Chinese SoC suppliers that do not have cellular baseband technology are at a disadvantage compared to companies such as MediaTek that also supply the smartphone market as white-box tablet makers increasingly add phone or cellular data functionality to their products.[18]

Intel Corporation has made significant investments into becoming a player in the tablet processor market and was heavily subsidizing its entry into the low-cost tablet market as of 2014.[14] In May 2014, Intel announced an strategic agreement with Rockchip to jointly deliver an Intel-branded mobile SoC platform based on Intel's Atom processor and 3G modem technology.[3]

Early Products[edit]

RK26xx series - Released 2006.

RK27xx series - Rockchip was first known for their RK 27xx series that was very efficient at MP3/MP4 decoding and was integrated in many low-cost personal media player (PMP) products.

RK28xx series[edit]

The RK2806 was targeted at PMPs.

  • ARM926EJC 600 MHz CPU + DSP Core
  • SD, DDR RAM support
  • Up to 1280×720 h.263 and h.264 software video acceleration.

The RK2808A is an ARM926EJ-S derivative. Along with the ARM core a DSP coprocessor is included. The native clock speed is 560 MHz. ARM rates the performance of the ARM926EJ-S at 1.1 DMIPS/MHz the performance of the Rockchip 2808 when executing ARM instructions is therefore 660 DMIPS roughly 26% the speed of Apple's A4 processor. The DSP coprocessor can support the real-time decoding of 720p video files at bitrates of up to 2.5 Mbit/s. This chip was the core of many Android and Windows Mobile-based mobile internet devices.[citation needed].

The RK2816 was targeted at PMP devices, and MIDs. It has the same specifications as the RK2806 but also includes HDMI output, Android support, and up to 720p hardware video acceleration..

The RK2818[19] was targeted at MID and E-reader devices. As of 2013, it was targeted at E-readers.[20]

RK29xx series[edit]

The Rockchip RK291x is a family of SoCs based on the ARM Cortex-A8 CPU core. They were presented for the first time at CES 2011. The RK292x are single core SoCs based on ARM Cortex-A9 and were first introduced in 2012.

The RK2918[21] was the first chip to decode Google WebM VP8 in hardware. It uses a dynamically configurable companion core to process various codecs. It encodes and decodes H.264 at 1080p, and can decode many standard video formats including Xvid, H.263, AVS, MPEG4, RV, and WMV. It includes a Vivante GC800 GPU that is compatible with OpenGL ES 2.0 and OpenVG. The RK2918 is compatible with Android Froyo (2.2), Gingerbread (2.3), HoneyComb (3.x) and Ice Cream Sandwich (4.0).[22] Unofficial support for Ubuntu and other Linux flavours exists. As of 2013, it was targeted at E-readers.[20]

  • ARM Cortex-A8 processor, clocked at up to 1.2 GHz (due to stability reasons often limited to 1 GHz)

The RK3028 is a low-cost dual-core ARM Cortex-A9-based processor clocked at 1.0 GHz with ARM Mali-400 GPU. It is pin-compatible with the RK2928. It is used in a few kids tablets and low-cost Android HDMI TV dongles.[30]

RK31xx series[edit]

The RK3188 was the first product in the RK31xx series, announced for production in the 2nd quarter of 2013. The RK3188 features a quad-core ARM Cortex-A9 clocked up to 1.6 GHz frequency.[31][32] It is targeted at tablets and Android TV dongles and boxes,[20] and has been a popular choice for both tablets and other devices requiring good performance.

The RK3188T is a lower-clocked version of the RK3188, with the CPU cores running at a maximum speed of 1.4 GHz instead of 1.6 GHz. The Mali-400MP4 GPU is also clocked at a lower speed. As of early 2014, many devices advertised as using a RK3188 with a maximum clock speed of 1.6 GHz actually have a RK3188T with clock speed limited to 1.4 GHz. Operating system ROMs specifically made for the RK3188 may not work correctly with a RK3188T.[34]

The RK3168, first shown in April 2013, is a very low power dual core Cortex A9-based CPU, also manufactured using the 28 nm process.[35][36] It is targeted at low-end tablets.[20] The chip has seen only limited use as of May 2014.
