Data Acquisition & Processing System Based On Bus And DSP

Data acquisition and the signal processing technology now already the more and more widespread application each domain which moved to the humanity. In the data acquisition system the computer bus technology plays the important role , at present the computer bus technology was also already mature. The thesis mainly introduce two kind of data acquisition systems based on VMEbus and the PCIbus, revolves their research, the design and the realization launches.This thesis main research work specifically contains following several aspects content: Design and debugging high speed multi-channel signal acquisition and processing system based on computer bus hardware circuit; Design and compilation computer bus connection logical control and succession; Fast correlation algorithm's software programme on the digital signal processer (DSP).Hardware circuit design of the high speed multi-channel signal acquisition processing system based on VME and the PCI two kind of computers bus is the main part of this thesis. In two systems separately used CY7C960 and PCI9054 as VMEbus and the PCIbus connection chip.The thesis also detailedly introduces the PCIbus LOCAL-part control and the logical succession programme which mainly realizes with the VHDL hardware programming language on FPGA.In the DSP software programme,the thesis accomplished the fast correlation algorithm on the DSP TMS320C6713. The thesis accomplished correlation operation on acquisitioning data by fast correlation algorithm which improve the speed of signal processing.We hope the study would be some instructive service for further study on the research and design of data acquisition and processing system based on computer bus.
