Design of High Speed Data Acquisition System Based on ARM9

Along with technology of radar,communication,telemetry and remote sensing development,the implementation of data acquisition system requires rigorous requests on speed,precision,data storage and so forth.All the questions referred above needed to be solved in the high speed data acquisition system.Based on the ARM9 structure of the high speed data acquisition system,the key techniques,including the analog signal adjusting circuit,clock circuit,data storage and transmission,anti-interference and so on,are analyzed in detail.And the corresponding measures are discussed.
