A new type of 8-channel data acquisition system based on FPGA

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.
