| Abstract: | A multi-channel synchronization data acquisition system was designed based on PC/104 bus,it can achieve simultaneous sampling of multiple channel in one conversion cycle of ADC.The logic control is performed by FPGA and FIFO integrated by FPGA is used as buffer,so we can use resources of FPGA in large.At the same time,it simplified the hardware circuit and improved configuration flexibility. |
