摘要
介绍了一种基于32位开放源代码的OpenRISC1200处理器嵌入式SoC的设计方案。系统以OR1200为核心,开发基于Wishone总线的IP核,并集成到OR1200系统中,构成了系统的硬件平台。软件部分构建了基于OR1200系统的交叉编译环境,开发了系统的启动程序Bootloader,移植了μC/OS-Ⅱ操作系统。
This paper introduces the design schedule of embedded SoC based on OpenRISC1200 which is a 32 bit open source code. The hardware platform of the system is as follows. The processor system core is OR1200. And the development is based on Wishone bus IP cores, and then integrated into OR1200 system. The software builds the cross-compile environment, develops the system＇s bootloader, and transplants ports the μC/OS-II operate system.
