Abstract:
A H.264/AVC Baseline Profile decoder is presented. The decoder is based on a hybrid pipeline architecture. In addition, several optimizations such as increased parallelism and optimized memory structure are adopted to improve overall system performance. Simulation results show that the decoder requires only 1.5 MHz for QCIF 30 fps real time decoding. The proposed decoder is designed for low-power applications such as mobile multimedia devices and cell phone.
