摘要
信号到达波方向估计（ＤＯＡ） 要求实时性强、运算速度快、估计精度高。单一的ＤＳＰ或ＰＣ机处理已远远不能满足实时性要求。本文介绍了以２０ 片ＴＭＳ３２０Ｃ３１ 芯片组成的多ＤＳＰ芯片并行处理系统的设计实例，并给出了系统硬件组成和软件设计。
The signal's DOA estimation requires intensively real-time estimation, fast calculation and high precision. Processing with single DSP or PC cannot handle it real-timely. An example of multi-DSP chips' parallel processing system is discussed in this paper, which consists of 20 TMS320C31 chips, and the frame of hardware and software design are discussed in the meantime.
