This paper develops a CPCI bus interface multiple intelligent signals collecting card with ADSP-21262 DSP con-troller , in order to meet the needs of real-time digital signal acquisition and process for the field of industral control . The DSP processor collects and processes the digital signals real-timely , then the processed data is transmitted to the master computer by CPCI bus interface . The board can collect and process the signals intelligently and real-timely by the high preformance DSP arith-metic . The application shows that this board runs stably and reliably , which can meet the requirements of system well .
