Abstract: A system and method for locking data in a cache memory. A first processing thread may be operated to run a program requesting data, where at least some of the requested data is loaded from a source memory into a non-empty cache. A second processing thread may be operated independently of the first processing thread to determine whether or not to lock the requested data in the cache. If the requested data is determined to be locked, the requested data may be locked in the cache at the same time as the data is loaded into the cache.

Abstract: Embodiments of the invention are directed to a system and method for dynamically defining a search area in a previously-coded reference picture during motion estimation in video encoding. The method includes receiving a sequence of pictures that are divided into a plurality of digital data blocks and defining for a currently-coded data block of a currently coded-picture, a search area within a previously-coded reference picture based on one or more search areas associated with previously-coded data blocks of the currently-coded picture, for example the left data block and the upper data block and further on a search area associated with a previously-coded data block of the reference picture that is co-positioned with the currently coded data block.
