摘　　要：采用VHDL硬件描述语言,以Xilinx公司的FPGA为设计平台,设计实现了以开源软核MC8051为核心的控制单元,控制4路SSI协议模块的SoPC架构的通信控制器,并对通信控制器进行了功能仿真与验证。该控制器可灵活进行IP核模块扩展,并可作为外围处理机与TI公司TMS320C6000系列DSP进行互连通信,将慢速串行通信任务进行分离,从而减轻DSP的负担,提高系统的整体性能。The article designs and implements typical communication controller based on SoPC architecture in VHDL on the platform of FPGA of Xilinx corporation with the open source code MC8051 IP core as the central control unit,which manages four same SSI modules,and the controller has been functionally simulated and verfied.The communication controller may flexibly add other IP core modules, and be used as a peripheral communication process unit and interconnect with TMS320C6000 series DSP of TI. It can separate the slow serial communication tasks, relieve the burdens of main controlling DSP,and improve the overall performance of system.
