摘要
根据基于ADSP TS-101的外辐射源雷达实验系统中脉冲压缩算法的特点和处理器的结构特点,提出了一种可以提高脉冲压缩子系统性能的方法。本方法充分利用ADSP TS-101内部6Mb的存储空间,将脉压算法中的FIR运算分解为4组并行运算单元,再按照一定的方法将结果进行累加。因为充分利用了每一次传入片内的数据,避免了数据的重复传输,大大减少了ADSP TS101与片外存储空间的数据通信量,提高了运算效率。文中给出了基于ADSP TS101数字脉压算法的改进方法的程序流程图及效率分析。
Based on characteristics of both ADSP-TS101 and the algorithm of digital pulse compression,this paper presents a method to improve the performance of the pulse compression subsystem in a external illuminating radar experimental system. This method makes full use of the SRAM in ADSP-TS101 and divides FIR algorithm into 4 parallel compute units. FIR operations can be performed at the same time. Then we can get several results at one time according to a certain method. This method can avoid transmitting the same data repeatedly,so the efficiency is enhanced. The flow charts based on ADSP-TS101 programing and efficiency analysis are presented.
