摘要
本文基于4G4处理模块设计了一种雷达信号处理机。4G4处理模块以四片高性能FreeS-cale公司G4芯片MPC7448为核心处理器,并结合了一片Xilinx公司FPGA芯片XC5V110T。文中介绍了4G4处理模块的技术特性,并给出具体的软件设计和工程实现方案。基于4G4平台的信号处理机通过合理设计的VPX总线互联结构、RocketIO高速串行接口、以及新一代通用G4芯片来实现信号处理的全部功能。其处理速度快、支持VxWorks实时操作系统。与传统的TS201平台相比,具有硬件结构体积小、程序易调试、可靠性和可维护性高的优点。
This paper introduces an universal radar signal processor based on the 4G4 processing module, which consists of four MPC7448 central processors and one XC5V110T chip of FPGA. Techno-characteristies of this 4G4 processing module, detailed software design and engineering project are presented. This system uses VPX bus, RoeketlO high speed serial interface and G4 chip to implement all signal processing functions. It has high processing speed and supports VxWorks realtime operating system. Compared with conventional TS201 system, this system features small size, flexible software programming and debugging, and high reliability.
