A new storage measurement system based on the PIC MCU CPLD(complex programmable logic device) and FLASH(large-capacity flash memory) is proposed.The design implement that in the variable sampling rate,FIFO cache achieve self-adapting function of the rate adjustment,and multi-channel data can be stored uninterrupted in FLASH memory.Using a new way of detecting FLASH invalid block,extend the using time of the system.The results show that the design can meet the requirement of acquisition system.
