Abstract :
H.264, which is the most advanced video compression standard till date, includes novel algorithms for quantization and inverse quantization processes. In this paper, a new hardware architecture exclusively based on combinational logic is proposed for the quantizer and inverse quantizer blocks for real-time video processing. Implemented in Xilinx14.1, Virtex-5 technology, the proposed architectures for quantizer and its inverse have demonstrated combinational path delays of 12.38 ns and 10.79 ns respectively.
