高速信号处理系统硬件的模块化设计

Modeled Design of High Speed Signal Processing Hardware System

TMS320系列器件具有工作速度快,运算能力强等优点,因而用它作为数字信号处理系统中的CPU是很有前途的。文[1,2]报道采用单片TMS320或一片Z80,8086,8031等加上TMS320芯片构成模块化的多处理器大系统。但这种系统一般都为专用目的而设计,通用性较差,若遇到运算量更大、计算更复杂的方案时就无法实时实现。同时,由于采用8031等芯片作为系统管理,增加了系统的复杂度,给系统的开发调试带来了困难。

A general purpose multi-processor digital signal proeessinG system based on TMS32010 chips is presented in this paper.It works at the master- slave mode.The master system is a complete general purpose digital signal processing system including data acquisition and processed result output,and can work independently.The slave system is designed to be a general purpose data processing system with a standard structure.The advantages of the system are flexible,variable,reliable,simple,etc.And the system can be built accor- ding to different calculation amount.At the same time the system is compati- ble with S-100 standard bus. So it can be used to process all kinds of digital signal with large calculation amount.The preliminary result obtained will push the digital signal processing hardware system to be designed with a standard structure and for general purpose.
