ABSTRACT:
An improved printing machine for concurrently processing first and second sets of image data is provided. The printing machine preferably comprises a video processor, capable of processing the first set of image data, a system memory, adapted to store the second set of image data, and a bus for transmitting image data, addresses and control data thereacross. Both of the video processor and the system memory are coupled with the bus. Additionally, an apparatus for transferring the second set of image data between the input/output device and the system memory substantially concurrent with the first set of image data being processed in the video processor is provided. The transferring apparatus preferably transfers the second set of image data in response to receiving a signal from the input/output device.
