Abstract
The basic section of the multimedia data-processing system includes a CPUan image display unita unified memorya system busand devicesandconnected to the system bus. In this configuration, the CPU is formed on an LSI mounted on a single silicon wafer including instruction processing unitand display control unitMain storage areaand display areaare stored within the unified memory. Unified memory portfor connecting the corresponding LSI and the unified memory is provided independently of the system bus intended to connect the LSI and the input/output devices. The unified memory port can be driven faster than system bus.
