Abstract
According to one exemplary embodiment of a buffer clearing apparatus for computer graphics, a buffer clearing (BC) hardware agent is configured to interface between one or more system buses and a memory controller, to execute one or more frame buffer clearing operations while performing memory access or power of buffer-related operations at the same time. The BC hardware agent keeps track of a plurality of status to read from and/or write to a frame buffer. When the frame buffer is to be cleared, the BC hardware agent clears a clear tag table. When a background pixel of the frame buffer is to be read, the BC hardware agent returns a background value stored in itself.
