摘　　要：为解决NoC协议芯片内部各个IP的初始化配置功能以及NoC芯片内部状态检测问题,设计芯来ICB总线转接AMBA总线的协议转换桥,基于芯来E203搭建配置管理单元与NoC芯片不同IP进行互连,从而实现NoC芯片的初始化配置以及管理工作,并从模块级、系统级以及FPGA原型3方面对系统进行验证。验证结果表明,配置管理单元系统的正确性扩大了芯片的应用范围。In order to solve the initialization configuration function of each IP in the NoC protocol chip and the internal status detection of the NoC chip,a protocol conversion bridge is designed to transfer the ICB bus to the AMBA bus,and a configuration management unit is built based on the core E203 to interconnect different IPs of the NoC chip,so as to realize the initialization configuration and management of the NoC chip.The system is verified from three aspects:module level,system level and FPGA prototype.The test results show that the correctness of the configuration management unit system improves the application scope of the chip.
