Colour Processor Interface ASIC
sending a compressed image stream to the host the amount of data to be sent for each image frame can
vary, depending on the compression ratio achieved. To enable the host to detect the end of valid image data
the device inserts four 0xFF values into the image stream to mark the end of image frame. As a sequence of
four 0xFF values will never occur within a valid frame of image data the host can use this to simply detect the
end of the image data, without having to decompress the image. The host driver checks the intergrity of the
image data stream before it is decoded. If any corruption is detected the frame is discarded and another
uploaded.
