本文首先对32位开源CPU(OR1K)进行了介绍,然后对基于此CPU的SOC(System On Chip)片上系统设计、仿真、调试进行了介绍。SOC系统采用的总线是开源的Wishbone总线,系统中集成的IP都是开源的。本文还对Linux操作系统下SOC仿真验证环境进行了介绍。
This article first introduces the 32-bit open-source CPU (OR1K), and then introduces the system-on-chip SOC design, simulation and debugging based on this CPU. SOC bus system is an open source Wishbone bus, integrated IP system are open source. This article also introduces the SOC simulation verification environment under the Linux operating system.
