Abstract:

Based on FIFO+CPLD, a type of data acquisition system with high-speed and high-precision was designed in this paper. The system used an ARM9 processor S3C2440 as controller and combed ADC ADS7891, FIFO buffer memory chip IDT7205 and CPLD, The CPLD realized the precise timing control logic and the FIFO buffer completed the data transmission between A/D and ARM.

Key words: A/D, CPLD, ARM, FIFO
