Abstract :
This brief presents an in-place computing design for the deblocking filter used in H.264/AVC video coding standard. The proposed in-placed computing flow reuses intermediate data as soon as data is available. Thus, the intermediate data storage is reduced to only the four 4 × 4 blocks instead of whole 16 × 16 macroblock. The resulting design can achieve 100 MHz with only 13.41K gate count and support real-time deblocking operation of 2K × 1K@30 Hz video application when clocked at 73.73 MHz by using 0.25-μm CMOS technology.
