Graphic processor and graphic processing system

摘要

The rendering performance of a graphic processor is improved by effectively using a data bus. An externally-input graphics command is stored in a work memory via the data bus. A display data generation section receives a graphics command stored in the work memory via the data bus, decodes the received graphics command, and outputs the display data to the data bus. An image display section receives display data stored in the work memory via the data bus, and displays an image on a display device. A bus control section monitors the status of use of the data bus, and controls the right to use the data bus according to the priority of each data transfer operation.
