Dsp Technology-based Data Acquisition System Software Technology

The text discusses the primary steps and processes of the software system design of Data-Acquint card which bases on the DSP processor and USB communication interface and is using in online-estate inspect of the industrial testing system.The text describes this field background and analysis the characters of the appliance object of Data-Acquint card, then offers a blueprint of the Data-Acquint card systerm. The text puts the emphasization on the detailed system design of the DSP software, the datasheets be used and the distributing of the resourse. It also describes carefully on LF2407 processor's resourses which is one wide-apply processor of the TMS320 DSP series of Texa Instrument Company and the software development tools, Code Composer Studio(CCS). Depent on those resourses and tools, the author designs and composes the program of Data-Acquint-Model. The author also ananlysises carefully the implement of Fast Fourier Transform, the most classical application on the digital signal processment, based on the point-bit DSP processor.The author has finished all the steps of the Data-Acquint systerm design which bases on the technology of DSP and USB. The author also completes all the design documents and gives the most important programs of the Data-Acquint systerm software.
