摘要
针对ADI公司虎鲨处理器的性能和特点,提出由4片TigerSHARCDSP101芯片构成的基于标准cPCI总线的紧耦合信号处理系统;对各DSP间的连接方式、数据传输和软件控制进行了分析。该系统成功应用于某雷达的信号处理机,并行实现自适应滤波处理、相关积累和横虚警检测等处理,对其雷达的主要信号处理模块在系统中的实现算法进行分析,估计其运算量。运行结果表明,其多DSP构成的系统不仅可行,而且结构简单?易于实现且处理能强。
For the characteristics of ADI TigerSHARC processor, a standard cPCI bus based close coupling signal processing system consisting of 4 ADSP-TS101s is put forward.The connecting way among each DSP and data transmission and software control are analyzed.The system is well applied to signal processor of certain radar, signal processing such as adaptive filtering, correlated accumulation and CFAR, etc. are realized simultaneously. The main realizing method is analyzed and the operand is estimated. The result indicates that the system not only is feasible, but also is simple and is easy to be realized, and has powerful processing capability.
