摘　　要：以FPGA为核心控制模块,搭载MAX1300为数据采集模块,完成8通道、16位精度数据采集系统。采集数据在FPGA内部储存,DSP在适当时刻对其进行读取以完成伺服控制工作。针对以往数据采集系统的局限,FPGA内部对所采集数据进行预处理,减轻了CPU数据处理强度和负担。详细介绍了各芯片硬件电路设计,给出FPGA内部各功能模块逻辑图。Adopting FPGA as kernel controlling module and MAX1300 as data acquisition module, a new data acquisition system is described. The system achieves 8-channel and 16-bit precision. The acquired data is stored in the FPGA and is read by the DSP to complete the servo-control task. To make up for the formal systems, the FPGA deals with the acquired data before it is read by the DSP, and that eases the workload of the CPU. The paper describes the hardware design scheme of the chips, as well as the logic blocks of the internal functional modules of the FPGA.
