摘要

本文介绍了使用带有多问题汇编指令的数字信号处理器(dsp)处理信号时计算并行性的各个方面。我们介绍了当代dsp的一般特征，并特别关注了VLIW架构。为了说明多问题指令技术，我们选择了在VisualDSP++ 4.5环境下使用Software Development Kit 2.01实现的典型信号处理任务，分析了定点Blackfin处理器的性能。使用Sharc和TigerSharc处理器分析了浮点处理的各个方面。

Parallel digital signal processing using multi-issue instructions

This paper presents aspects of parallelism of computations in processing of signals using digital signal processors (DSPs) with multi-issue assembler instructions. We present general features of the contemporary DSPs with special attention paid to the VLIW architecture. In order to illustrate the multi-issue instruction technique we analyze performance of the fixed-point Blackfin processor by means of chosen typical signal processing tasks realized using VisualDSP++ 4.5 environment with Software Development Kit 2.01. Aspects of the floating-point processing are analyzed using Sharc and TigerSharc processors.
