一种基于PowerPC的信号处理模块在软件化雷达中的应用

摘要

This study introduces the software radar's requirements on signal processing system and introduces a high performance PowerPC multicore processor MPC8641D. The differences between this processor and the traditional DSP on processing performance and interface are compared and at the same time a software development flow aiming at this embedded processor is deliberated. A commonly used signal processing method realized on the signal processing module with the core of PowerPC multicore processorMPC8641D is provided. last but not least, this study makes further expectation on the multicore processor's use and development in future software radar.%介绍了软件化雷达对于信号处理系统的要求以及一种高性能的PowerPC多核处理器MPC8641D，比较了该处理器与传统DSP在处理性能以及接口方面的差异，并介绍了针对该嵌入式处理器的软件开发流程。给出了一种常用的信号处理算法在以PowerPC多核处理器MPC8641D为核心的信号处理模块上的软件设计。最后对于多核处理器在未来软件化雷达中的应用和发展作出了展望。
