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.

Abstract: A performance analyzer analyzes occurrences of virtual events generated by platform components. A user may define and select the virtual events to be analyzed. The performance analyzer comprises a virtual event provider manager and a plurality of virtual event provider drivers, Each of the virtual event provider drivers is associated with one of the platform components to provide a definition for the virtual events supported by the associated platform component. During a registration process, the virtual event provider manager queries the virtual event provider drivers about the supported virtual events, and provides, the results to the interrupt vector table. Thus, when a selected virtual event occurs, the processor execution may be interrupted and the interrupted instruction may be stored for analysis.
