Abstract

Frames of digital data each representing a single picture of a video motion picture display are handled in a computer system with an extended memory operating in parallel with a computer system instruction processor and main memory to bypass the computer system input/output processor for continuously outputting the video information on a real time basis. The outputted data may be recorded continuously at a constant data rate for an entire motion picture worth of information or actually displayed on the video display on a real time basis. The extended storage has a memory larger than the main memory, where all of the frame data is stored and read out in high speed bursts to a buffer that continuously reads the data out of the buffer for outputting. At least a start command and a starting address in the extended memory are contained within the main memory to be read out and decoded by the instruction processor and computer system memory storage control, for transfer to the extended memory, where they are used to start the program, which includes extended memory control words stored in the main memory, which control words are decoded and executed in the extended memory in parallel wit…
