Abstract:
The traditional data acquisition are generally based on CPU under the control of A/D conversion and data storage technology. Due to the limitation of CPU instruction execution time series,this kind of control mode is difficult to break through the above 1 MHz data sampling rate. This paper introduces a kind of high-speed A/D conversion based on FPGA,data acquisition,storage control technology. The data acquisition system adopts FPGA chip EP4CE6E22C8N of ALTERA company as the controller,to produce high-speed A/D converter and the large capacity SDRAM memory work required sequence control signal,the collected rate of up to 100 MHz high speed A/D conversion chip AD9283 sampling control and deal with fast cache. The whole design is on the QuartusⅡ with KeilC-51 platform,by using Verilog language and C language,designs software programming,correctly implements AD9283 transformation work timing control and sampling data storage process.
