An Efficient Hardware Architecture for H.264 Adaptive Deblocking Filter
Mustafa Parlak, İlker Hamzaoğlu · 2006
This paper presents an efficient hardware architecture for real-time implementation of adaptive deblocking filter algorithm used in H.264 video coding standard. This hardware is designed to be used as part of a complete H.264 video coding system for portable applications. We use a novel edge filter ordering in a macroblock to prevent the deblocking filter hardware from unnecessarily waiting for the pixels that will be filtered become available. The proposed architecture is implemented in VerilogHDL. The Verilog RTL code is verified to work at 72 MHz in a Xilinx Virtex II FPGA. The FPGA implementation can code 30 GIF frames (352 times 288) per second
