用TMS 320 C 25与PC机构成通用数据采集系统设计

A Design of General Data Acquisition System with TMS 320 C 25 and PC

为了更好地解决数据采集系统主从机之间大规模数据传输的问题 ,该文设计了一种用TMS 32 0C 2 5与PC机构成的并行高速数据采集系统。该系统以PC机作为主机 ,TMS 32 0C 2 5专用数字信号处理器作为从机 ,并采用双端口存储器进行并行通讯。借助双端口存储器结构 ,还使系统具有利用PC机对TMS 32 0C 2 5进行简易开发的功能。该设计较好地解决了主从机之间大规模数据传输的问题 ,且结构简单 ,通讯快速 。

In order to better solve the question of data transfer from the slave system to the master one,a general parallel high speed data acquisition system with digital signal processor TMS 320 C 25 and PC,is designed in this paper.The system uses PC as its master computer and TMS 320 C 25 as the slave microprocessor,also adopts shared memory for parallel communication.Based on the shared memory structure,the system,using PC,can also develop simply TMS 320 C 25 processor.Question of data transfer from slave system to the master one is better solved in the system. The system is simple in structure and communication speed is very fast.The advantages of TMS 320 C 25 have been made good use of.
