摘要
An apparatus is described for attaching a motion search hardware assist unit to a processing element and its local memory. A current macro block storage unit is attached to a local memory interface unit for storage of a copy of a current macro block from the local memory. A search window reference storage unit having N rows is attached to a local memory interface unit for storage of a copy of N rows of pixels from a search window from the local memory. N independent arithmetic pipelines are attached to the current macro block storage unit and the search window reference storage. Each pipeline operates on one of the N rows of the search window reference storage unit and a corresponding row of the current macro block of the current macro block storage unit. An accumulator is attached to the N independent pipelines to accumulate results from the N arithmetic pipelines, to produce independent results for different organizations of macro blocks.
