Advanced Design of TQ/IQT Component for H.264/AVC Based on SoPC Validation

摘要

This paper presents an advanced hardware architecture for integer transform, quantization, inverse quantization and inverse integer transform modules dedicated to the macroblock engine of the H.264/AVC video codec standard. Our highly parallel and pipelined architecture is designed to be used for intra and inter prediction modes in H.264/AVC. The TQ/IQT design is described in VHDL language and synthesized to Altera Stratix II FPGA and to TSMC 0.18 μm standard-cells. The throughput of the hardware architecture reaches a processing rate up to 1070 millions of pixels per second at 171.4 MHz when mapped to standard-cells. In addition, a system on a programmable chip (SoPC) implementation and validation of the proposed design as an IP core is presented using the embedded Altera development board.
