A parallel luma-chroma filtering architecture for H.264/AVC deblocking filter

A novel architecture for the H.264/AVC deblocking filter is proposed. It includes three filtering units to filter in parallel the luma and chroma components. Also, a proper two dimensional filtering order for the luma edges and a one-dimensional filtering order for the chroma edges are presented. The architecture achieves 750 MHz in 560 MHz in 90nm and 130 nm, respectively, and requires 76 cycles to filter each MB. Compared to existing architectures, it outperforms them in frequency and throughput, while it is the only one that achieves over 60 Fps in 8K-UHD resolution.
