DRAWING DEVICE AND DISPLAY CONTROLLER

摘要

A rendering apparatus includes a low-speed frame buffer (21) and a first temporary memory (26) and a high-speed and small capacity second temporary memory (27). The first temporary memory rendering unit (23) subjects a rendering result already stored in the first temporary memory (26) and a rendering result of rendering to be applied to the first temporary memory (26) to blend processing and stores a result of the blend processing in the first temporary memory (26). The same is true for a second temporary memory rendering unit (24) and the second temporary memory (27). A frame buffer rendering unit (22) subjects a rendering result already stored in the frame buffer (21) and rendering results stored in the first temporary memory (26) and the second temporary memory (27) to bend processing and stores a result of the blend processing in the frame buffer (21).
