In recent months, many of the original tablet CPU does not fade out our vision, but also emerged in some of the new CPU chip, high-end series, including NVIDIA, Samsung, Qualcomm, Texas Instruments dual-core / quad-core processors.
The appearance of Allwinner A10, the Vimicro VC0882, JZ4770 ,make domestic tablet pc market speeds up to the GHz level. Overall, the mainstream flat-panel chips have already entered the Cortex A8/A9 core era, now moving to a high frequency, the direction of multi-core and more advanced technology.
The upgrade of Android device hardware are continuing.International brands naturally leading the advance of high-end flat, the local large number of small and medium-sized manufacturers basically occupy the entry-market. The followings are the perspective of functional applications to provide new reference
Cortex A8 series , the Samsung S5PC110/S5PV210 is undoubtedly one of the best famouse, the overall performance of the basic operators of the strongest standards in addition to video decoding. Freescale i.MX515 come to market for a long time, the parameters are relatively low, not high degree of concern, and therefore no longer included,OMAP3630 Series Texas Instruments OMAP3621 are basically the same level, the main reason why we collect is the recent hot saleing of Lenovo tablet Music Pad A1(Basic on OMAP3621).Rockchip RK2918 firmware just come imperfect, now the emergence of SDK2.0 and transplantation of the Android 4.0 system, have made great progress from the performance, combined with the corresponding large number of products, the natural focus of the crossline one.
ARM9/ARM11 old architecture basically disappeared in the mainstream of tablet pc CPU market, the ARM family members of the Cortex A5 and A15 architecture there is no formal application, the current mobile microprocessor platform can be considered on the A8/A9 the world.

Cortex A9 , AML8726-M as the leading local mainstream of tablet pc CPU into a program of the A8/A9 grade to play with the waste heat is still on the market, although the Redu smaller than the RK2918 and QUAN Zhi A10, but there are still sound Yue DepartmentChi, Ainol brand of several representative products. The NEC EV2 CPU the A9 of the dual-core, but the frequency is too low, the GPU is not too advanced, the overall degree of concern is not high, the number of related products and rarely included in the crossline range. NVIDIA Tegra 2 as the "Queen" before the honeycomb plate configuration, continues to occupy many of the high-end flat share, continue to join in to. Texas Instruments OMAP4430 previously only used on the BlackBerry PlayBook become another hot Following Tegra 2 processor is used in the Amazon Kindle Fire and B & N the Nook the Tablet of these two cost-effective hot plate, but as of press before detailed evaluation has not been completed, coupled with the current is not a native system, for the time being is not easy to do comparison. Several other CPU left, Samsung, Orion tablet has not been evaluated by the Apple A5 chip iPad not the Android system, NVIDIA Tegra 3 tablet not yet listed, so not to join the contrast.
