Abstract
An embodiment of the present invention includes a multi-core processor that processes video data. The control core controls a first processing core to process a first set of data blocks of an image frame according to a stairstep pattern. The control core detects, while the first processing core is processing the first set, that a triggering data block has been processed in the first set. The control core controls, while the first processing core is processing the first set, a second processing core to process a second set of data blocks using information from the triggering data block. By processing data blocks in the stairstep pattern, cache hit rate is improved, resulting in improved video decoder performance.
