Full master chip Introduction of A10 Tablet PC

1. Introduction

With ARM Cortex A8 core, A10 will drive SoC into a brand new era of connected Smart HD which can enhance the application of connected HD SOC as well as user experiences of consumer electronics like multimedia products. Due to its outstanding connected HD video performance and cost efficiency, the highly integrated A10 is target at cool HD pad which can bring end-users better experiences of surfing, watching, gaming and reading.

The A10 is dedicated to furthering the development of connected HD video CODEC application, and 1080P H.264 high profile encoding technology can become one of the benchmarks. Besides its remarkable super HD 2160p video decoding capability, A10 can stream smoothly HD video over internet, including FLASH10.3/HTML5/3RD APK.

Besides self-developed display acceleration frame, MALI400 2D/3D GPU has also been introduced to strengthen the connected smart HD SOC in terms of high profile display so that it can support popular smart systems such as Android2.3/3.0 better and improve the performance of Android-loaded products as well as user experience.

There is no doubt that low power consumption and excellent user experience will be always on the top of end-users‟ wish list. A10 has adoped Allwinnertech‟s most advanced technology of video CODEC and power consumption is much lower during 1080p decoding process. What‟s more, Allwinnertech will keep applying progressive VLSI design under new process so that end products can become even more competitive with shorter R&D cycle and easier production advantages.
