Picture storage apparatus and graphic engine apparatus.

摘要

A memory Mi has a storage capacity one-sixteenth of a memory capacity corresponding to the resolution of a display screen. A pixel processor XPi controls readout and writing of pixel data from or in memory Mi via an input/output port IO1 and finds a number j of the pixel processor XPi of a destination area of pixel data to transfer pixel data read from memory Mi via TBus 19 to pixel processor XPi of the destination area in the sequence of an increasing number j. The pixel data stored in memory Mi is read out by raster scanning so as to be converted into RGB signals by a video processing circuit 17. A Braun tube 18 displays a picture based on the RGB signals. <IMAGE>
