In this paper, the low-complexity hardware architectures of 4×4 forward and inverse transforms with integrated quantizer and dequantizer for H.264 advanced video coders (AVC) are proposed. By applying the regularity of the quantization matrix, the quantization can be merged into transform step, which results in the reduction of the hardware complexity in VLSI implementation. The proposed integrated transforms have been synthesized with TSMC 0.35 μm technology. Simulation results show that it can achieve 256 M samples/sec at 32 MHz in encoder part and 448 M samples/sec at 56 MHz in decoder part, respectively.
