Abstract
A system and method for filtering a frame, the method includes: (i) processing, by a processing unit executing instructions, at least one portion of a frame to provide at least one processed frame portion; (ii) performing, by a hardware filter, deblocking filtering of the at least one processed frame portion to provide at least one filtered frame portion; and (ii) storing the at least one filtered frame portion in a memory unit that is accessible by the processing unit; whereas the stage of processing is responsive to previously filtered frame portions. The system includes: (i) a processing unit, adapted to execute instructions such as to process at least one portion of a frame to provide at least one processed frame portion; (ii) a hardware filter, connected to the processing unit, adapted to deblocking filter the at least one processed frame portion to provide at least one filtered frame portion; and (iii) a memory unit, connected to the processing unit, adapted to store the at least one filtered frame portion; whereas the processing unit is adapted to process the at least one portion in response to previously filtered frame portions.
