基于uC/OS-II的“龙芯1”SoC验证方法

Verification Method of SoC Integrated with GODSON-1 IP Core Using uC/OS-II

片上系统(SoC)的设计日益复杂,规模趋于庞大,这使得SoC的功能验证与测试成为IC设计的瓶颈.uC/OS-II是一种简洁的、可移植的、可裁减的与支持多任务的嵌入式实时操作系统.本文介绍了uC/OS-II在基于"龙芯1"SoC上的移植工作,重点讨论了在虚拟仿真与FPGA验证平台两种环境下运行uC/OS-II及其上层应用程序来测试"龙芯1"SoC的方法,并取得了良好的效果.

The design of system on chip （SoC） becomes more and more sophisticated,and chip size is also increasing rapidly. Thus,it makes functional verification and testing of SoC the bottleneck in IC design, uC/OS-II is a simple ,portable,scalable, preemptive, multitasking real time OS（RTOS）. This paper introduces how to port uC/OS-II to the SoC platform integrated with GODSON-1 IP core and focuses on the verification and testing of the SoC using uC/OS-II in virtual simulation environment and FPGA platform,and it achieves good result in our SoC design.
