Abstract
How to meet the requirement of 3C fusion better,is the very key point of popularization of Ultra-Mobile Personal Computer(UMPC).PKUnity-SK SoC integrates the CPU,North/South Bridge chipsets,display controller and other I/O devices,which are distributed on the main board in traditional computer,into one single chip.Beyond the efficient processing of multimedia,PKUnity-SK SoC adopts 2D/3D extension instruction,HW/SW cooperated video decoding accelerator as well as hardware supported video encoding/decoding to reduce the demand for CPU performance.The hierarchical storage system in a single chip simplifies the data transfer path and increases the data transfer rate to improve the system performance.Furthermore,many popular I/O controllers are implemented on the SoC to satisfy I/O usage in personal computer.The design of PKUnity-SK SoC achieves the goal of high-integration,high performance and low power,providing a UMPC solution in low cost,low power,easy usage and easy maintenance for education,electronic government,and personal information processing.
