Design of CPCI Bus Intelligent Collectting Board on Based DSP Processor

针对工业控制领域对数字信号智能化实时采集和处理的要求,以TMS320 LF2x DSP控制器为核心处理器,开发了一种CPCI总线接口的智能数据采集板;高性能DSP控制器实现信号的实时采集和处理,处理结果通过CPCI总线接口与主机进行通讯,配合高效的DSP算法,实现了一种具有实时性好、可靠性高的信号智能数据采集处理板;应用结果表明,该智能数据采集板工作稳定可靠,满足系统要求,具有一定的实用性。

This paper develops a CPCI bus interface intelligent signals collectting board with the TMS320 LF2X DSP controller. The DSP controller collects and processes the digital signals Real-time, after processeed the data is transmitted to the the master computer by CP- CI bus interface. The board can collect and process the signals intelligently and Real-time by the high preformance DSP arithmetic. The application shows that this board runs stably and reliably. The technology and methods adopted in the system are practical.
