摘　　要：RapidIO总线是基于数据分组交换的高性能系统互联方案,广泛应用于无线通信、军事、超算、医学图像处理和工业控制等多个领域。目前国内使用的RapidIO芯片多来自美国,一旦美国对我国实施相关的断供,则势必威胁到我国的国家安全。文中提出并研究一种基于龙芯2K1000处理器和复旦微FPGA的RapidIO全国产解决方案,并结合具体项目验证了该方案的可行性。RapidIO bus is a high⁃performance packet switch system interconnection solution,which is widely used in the fields of wireless telecommunication,military,supercomputing,medical image processing,industrial control,etc.At present,most of the RapidIO chips used in China come from the United States.It will evidently push severe threats to our national security if the corresponding silicons are restricted.In this paper,an indigenous RapidIO solution based on Loongson Processor 2K1000 and Fudan Micro FPGA is proposed.Its feasibility has been verified by a specific scheme.
