数字信号实时处理仪器的研制

Development of Digital Signal Real Time Operation Instrument

介绍由微机和ＴＭＳ３２０－ Ｃ２５微处理器芯片构成的主、从并行机系统结构的数字信号实时处理仪器。文章叙述了仪器的硬件组成，并以传递函数的平均计算为例对仪器内的主机和从机工作的实时安排进行了分析。该议器实现了并行机三线流水作业，不但提高了信号处理速度，也扩大了使用范围。

This paper presents a kind of individual paralleloperating instrument called digital signal real time operation instrument. It is composed of microcomputer system and TMS320-C25 microoperator. Particularly, its hardwares are introduced. Taking the aveage calaulation of transfer function for example, the author makes an analysis of the real time operation tasks assigned for the main part-PC and the subordinte part. This instrument can accomplish the work of three line production with the main part and subordinte part together, thus not only improved the operating speed but also expand the range of application much more.
