UNIFIED SYSTEM/FRAME BUFFER MEMORIES AND SYSTEMS AND METHODS USING THE SAME

摘要

A processing system (100) includes a unified memory system (105) having a system memory area (109) and a plurality of frame buffer areas (110/111). A central processing unit (101) has within its address space unified system memory (105) and is operable to update display data in a first selected one from the frame buffer areas (110/111) while display data from a second selected one of the frame buffer areas (110/111) provides data for refresh of a display screen of an associated display device.
