Abstract：By adopting the combination of DMA and dual port RAM, we designed a multi-channel electromyographic signal acquisition system based on embedded technology.The sampling sequence of ADC device was controlled by FPGA;As the master device, ARM implementsed the high-speed communication between the up and down machine by using DMA.The paper presentsed a data acquisition interface design scheme, and the DMA driver under Linux and control instruction.Experiment shows that the system can do data acquisition, algorithm processing and real-time transmission at the same time, greatly improves the performance of the multi-channel electromyographic signal acquisition system.
