    • 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.
    • 一种用于过滤帧的系统和方法,所述方法包括:(i)通过执行指令的处理单元处理帧的至少一部分以提供至少一个经处理的帧部分; (ii)通过硬件滤波器执行所述至少一个经处理的帧部分的去块滤波以提供至少一个滤波的帧部分; 以及(ii)将所述至少一个滤波的帧部分存储在可由所述处理单元访问的存储器单元中; 而处理阶段响应于先前滤波的帧部分。 该系统包括:(i)处理单元,适于执行诸如处理帧的至少一部分以提供至少一个已处理帧部分的指令; (ii)连接到所述处理单元的硬件滤波器,适于对所述至少一个经处理的帧部分进行去块滤波,以提供至少一个滤波的帧部分; 和(iii)连接到所述处理单元的适于存储所述至少一个滤波的帧部分的存储器单元; 而处理单元适于响应于先前滤波的帧部分来处理该至少一个部分。
