Abstract: A novel storage format enabling a method for improved memory management of video images is described. The method includes receiving an image consisting of a plurality of color components. Once received, the plurality of color components is converted to a mixed format of planar format and packed format. The mixed packet format is implemented by storing one or more of the plurality of color components in a planar format and storing one or more of the plurality of color components in a packed format. A method for writing out video images is also described utilizing a write combining (WC) fame buffer. The decoding method motion compensates groups of macroblocks in order to eliminate partial writes from the WC frame buffer.

Abstract: Efficient performance monitoring for symmetric multi-threading systems is applicable to systems that have limited performance monitoring resources and enables efficient resource sharing on a per-execution unit basis. The performance monitoring unit being shared is programmed to reset its counter and to start performance monitoring operation if there is only one execution unit requesting this operation. In case there are several requests pending, an attempt is made to program the performance monitoring unit to collect performance data for a subset of execution units the hardware is capable to support. Upon a request to stop performance monitoring operation the previously allocated indicator may be removed, and the performance monitoring unit may be programmed to stop operating if there are no more active or pending requests. In case the performance monitoring was inactive for the current execution unit, this request may be discarded, and no performance data may be returned.
