摘要
采用ADI公司的TigerSHARC系列第二代超高性能DSP芯片ADSP-TS201S设计制作了一个高性能的数字波束形成(DigitalBeamForming,DBF)处理器。在这个硬件平台上实现了二维DBF算法,并对算法进行了优化。初步实验结果验证了软、硬件的正确性。对于一个由32个阵元组成的4×8平面阵,存在一个干扰源的情况下,DBF权重系数的计算时间为71.134μs,是TI的TMS320C6701所需时间的七分之一。
A high performance digital beam forming （DBF） processor is designed and implemented by using ADSP-TS201S. A two dimensional DBF algorithm is realized on this hardware platform by using Visual DSP ＋ ＋ software, and the program code is optimized. The experimental results show that the designed hardware and software are correct. For an 8 × 4 antenna array with one interfere signal, the computation time for DBF weight coefficients is 71. 134μs. The speed is 7 times as fast as that of TMS320C6701.
