Abstract:In order to improve the speed of data acquisition cards, while reducing costs, has designed a data acquisition system of pipelined storage. The system is controlled by the Software and hardware combination, through the MAX1308 completes of the ADC conversion process, using pipelined high-speed data storage mode to store the data collected. With hardware circuit, and in CPLD the system makes up the acquisition module, the control module, the storage module and the Nandflash storage using the VHDL language. Experiment results show that read and write chip timing signal corresponding to the location accuracy, timing does not appear chaotic, and acquisition speed maintain the 10Mb/s or more. The system realizes design requirements of low cost, high-speed multiplex acquisition.
