BYPASS TECHNIQUE OF PIXEL CLOCK GENERATING CIRCUIT AND CRT CONTROL CIRCUIT IN IMAGE CONTROL INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a method for providing a video data stream at a clock rate independent of a pixel clock rate in a video processor unit. SOLUTION: In the method, an inherent video data is received from a video source at an inherent clock rate, the video data is stored in a storage, a selected portion of the video data is read at a memory clock rate, the selected portion of the video data is rasterized, the rasterized video data is packetized, and the packetized video data is transmitted to a display unit through a link at a link rate based on the memory clock rate.
