In this paper, we present a bitstream parsing processor including emulation prevention bytes (EPB) removal for H.264/AVC decoder. The proposed bitstream parsing processor includes several specific instructions for bitstream parsing. Furthermore, it employs double bitstream buffers to remove EPBs for sequential bitstream parsing. Experimental results show that the proposed bitstream parsing processor...
This paper presents a fast context-based adaptive variable-length decoding (CAVLD) method of H.264/AVC with a very long instruction word-based bitstream processing unit (BsPU) designed for entropy decoding of multiple video formats. A new table mapping algorithm for the coeff_token, level, and run_before syntax elements of the quantized transform coefficients is proposed, and many branch operations...
