Abstract
A print controller with simplified video data storage operation. A single microprocessor provides a controller with a start address and a start command. The controller monitors a stream of digitized video data as it fills a two part serial register in a video random access memory ('VRAM'). As each successive part of the serial register is filled, the controller writes the contents of the filled part of the serial register to the VRAM. Upon receipt of a signal indicating the end of the image, digitized video data remaining in the register is written to the VRAM. Images are effectively streamed in, as opposed to the line by line storage of images used in known print controllers.
