Multi-Channel High-Speed Data Acquisition and Storage System

Based on the ADS8365, FPGA, this article gave out the design and implementation program of single-chip multichannel synchronous real-time data acquisition storage systems. The block schematic diagram of the hardware interface circuit and some key procedures have been shown. The design taking XC2S100, ADS8365, CY7C68013 as the core devices, used primarily for completing the measurement and storage mission in a vehicle test which included 12 road vibration, 4-way shocks, 4-way noise signal. After the external analog signal filtering and following through ,the FPGA control AD converting them into digital, and then stored in the flash memory. After the end of the trial, data can be read back through the CY7C68013, and we can split, display, and do project volume conversion processing such as operation.
