摘要
传统总线技术成为了制约短波通信系统性能进一步提升的瓶颈。RapidIO总线是一种新型嵌入式总线,具有传输效率高、系统成本低、系统稳定性好等特点。基于RapidIO技术设计了相控阵短波发信系统的交换单元,硬件上进行了系统供电电路、时钟电路和交换芯片端口电路设计;软件上主要介绍了RapidIO初始化和交换芯片的远程配置两个方面。在实际应用中实现了系统中各模块间信号的高速交换。
The traditional bus technology now becomes a bottleneck in further enhancing the control per- formance of shortwave communication system. RapidlO bus, as a new type of embedded bus, features high transmission efficiency, low system cost, good system stability etc.. The paper describes the phased-array shortwave communication system platform constructed in DSP and FPGA, including the design of TSI578 chip based on RapidIO switching unit. Hardware design mainly involves the system power circuit , clock circuit, and port circuit of the switching chip. As for the software, two aspects including RapidIO initial- ization and remote configuration of the switching chip are introduced. The unit can realize high-speed sig- nal switching of among various modules in the practical application of exchange
