Abstract

Direct macroblock mode techniques for high performance hardware motion compensation are described. An embodiment includes a hardware motion compensation graphics display device driver. More specifically, an embodiment mitigates a macroblock data parsing bottleneck in the display device driver by directly generating macroblock instructions and storing them in a dedicated buffer. For example, an embodiment includes an independent direct memory access instruction execution buffer for macroblock instructions separate from the direct memory access instruction execution buffer for all other hardware motion compensation instructions. Other embodiments are described and claimed.
