摘　　要：介绍以图像处理为应用背景、基于FPGA芯片建立的多软核系统设计。系统中包含两个Nios II软核处理器和两个用于进行图像颜色空间转换的CSC MegaCore IP核。两个NiosII软核处理器共享程序存储器、数据存储器及启动存储器。在硬件设计方面,CSC MegaCore IP作为外围组件通过一个自定义的接口控制器连接到以Nios II软核处理器为核心的SoPC系统中。在软件设计方面,运行在每个Nios II软核处理器上的程序通过硬件Mutex核协调对共享数据存储器的访问。A multi-core system based on FPGA to process image is designed in this paper. The system includes two Nios Ⅱ softcores and two CSC MegaCore IPs. The two Nios Ⅱ softcore share one program memory, one data memory which is used to store image data, and one Flash memory as start-up memory. In the hardware design, the CSC MegaCore IP acts as an periphery compercent and is connected to SoPC system centered by Nios Ⅱ softcore processor by an self-designed interface controller. In the software design, the application program cooprates the access to the shared memory.
