Based On The Tms320dm642 High-speed Image Acquisition System Hardware And Software Design

This article has developed the high speed picture gathering system based on the TMS320DM642 DSP; the system will apply to the picture processor of the TV-guided aerial bomb. The main research work of this high speed gathering system had:1) The article has elaborated the system design and the concrete realization of the picture gathering system, has designed hardware electric circuits of the high speed picture gathering system, has produced hardware circuits diagram: The video input channel, the video output channel, the standard UART communication circuit, the JTAG simulator connection electric circuit, the Flash electric circuit, the CPLD electric circuit, the power-switching circuit, the RESET circuit and so on.2) The article has programmed test procedures of partial hardware module and the video driver procedure.3) The power circuit, repositioned the electric circuit, the I C electric circuit, the SDRAM electric circuit and the video input output channel have been debugged, the present paper has elaborated the debugging process and has finally analyzed the result of the debugging, modules work normal, capturing and displaying picture were normal.
