Tiger SHARC系列的ADSP-TS101是ADI公司开发的一款高性能的利于并行处理的高速信号处理器。为了实现水下多目标定位算法的实时处理,设计并实现了由FPGA和ADSP-TS101构成的多通道同步采样和多处理器并行实时处理系统;该系统采用FPGA的逻辑控制,完成了多通道同步采样,采用多处理器并行结构,完成了多目标定位系统中方位估计算法的实时并行实现,解决了在水下多目标定位系统的多通道同步采样和大数据量的高速实时处理的问题;实验结果证明,该系统具有良好的稳定性和通用性,满足了多目标定位的高速实时处理要求。

ADSP--TS101, which belongs to the series of Tiger SHARC and is developed by ADI, is a high performance DSP with good properties of parallel processing and high--speed. In order to implement the real--time processing for the algorithm of multi--target tracking, a parallel real--time processing system with multi--channel synchronous sampling and multi--processor based on FPGA and ADSP-- TS101 is designed and implemented. FPGA logical control was adopted to realize multi--channel synchronous sampling, and the parallel construction with multi--processor was adopted to realize psrallel real--time processing （or the algorithm of orientation estimation in multi -target tracking. So the problems to multi--channel synehronous sampling and to high--speed real--time processing of great data are solved. From the results of experiments, the real--time processing system has good stability and real--time processing capability, so that it satisfied the requirements of high--speed real--time processing for multi--target tracking.
