基于DSP的数字波束形成算法优化实现

Optimized Validation of DBF Algorithm Based on DSP

在DSP上移植算法,代码优化程度成为提高系统性能、缩短开发周期的瓶颈。同时针对复杂算法在DSP上的实现,也产生很多优化策略、方法。本文介绍水声信号处理中广泛使用的数字式波束形成(DBF)算法,简述DBF的基本原理以及目标处理器(TMS320C6201)的处理能力;介绍C6000软件编程及优化步骤,并提出一些具体的优化策略和技巧。

The degree of code optimization turns out to be the bottle - neck of upgrading systemperformance and shortening developing period when replanting algorithms on DSPs, and thereare many methods Of optimization On realizing algorithms on DSps. The paper ex- patiates the widely used digital beam forming （DBF） algorithm in water acoustic and the processing ability of the processor （TMS320C6201） ,and introduces the programming and optimizing steps of C6000 and some material skills of the optimization.
