ABSTRACT:
A data reading and image processing system for a video entertainment system with a CD-ROM capability is disclosed with a pair of separate computer systems that are controlled through a controller for accessing data from a memory unit. A first computer system can control the reading of data and the storing of the data in the memory unit in coordination with a first synchronization time period while the second computer system can control the processing of video data signals in an image processing circuit during a second synchronization time period. The data can be appropriately enabled to a position within the memory unit to assist in parallel processing by both computer systems.
