摘要
针对合众达SEED-DEC系列化嵌入式DSP控制模块在数据采集功能上的不足,利用其标准的扩展总线和统一的结构,设计研制基于SEED-DEC扩展总线的多通道同步数据采集板。以DSP作为数据处理中心,FPGA负责与DSP通信、初始化和控制数据采集板上的A/D模块,以节省DSP内部资源,减少DSP因控制外围器件而消耗的时间,提高性能。试验结果显示电路达到了指标要求。
The paper contrapose the flaw of data acquisition in the SEED-DEC series embedded DSP control module and design the multichannel synchronous data acquisition board based on the expansion of the standard bus.In order to save the DSP internal resources and improve performance,we used the DSP as the data processing center and FPGA responsible for communication,and DSP initialization and control data acquisition boards on the A/D module.Experiment shows that this circuit works well.
