面向RapidIO控制器与片上网络的转换接口设计OACSTPCD

With the continuous improvement of embedded processor's performance,it is hard for the traditional parallel bus to satisfy the increasing requirement of bandwidth in embedded systems.RapidIO technology alleviates the contradiction between the traditional bus with slow development and the processor with high performance,meanwhile,network-on-chip have become the most commonly used in-terconnect structure in multi-core architectures.In order to realize the data interaction between RapidIO controller and network-on-chip,a conversion interface is designed,which can achieve the conversion of the RapidIO controller's AXI protocol to the internal packet trans-mission of the network-on-chip,and satisfy the needs of read/write operation of the RapidIO device.The simulation results show that the function of the conversion interface is correct and complete,and meets the design requirements.
