A high throughput context-based adaptive binary arithmetic coding (CABAC) decoding design with hybrid memory architecture for H.264/AVC is presented in this paper. To accelerate the decoding speed with hardware cost consideration, a new hybrid memory two-symbol parallel decoding technique is proposed. In addition, an efficient mathematical transform method is also proposed to further decrease the...
In this paper, the first overall memory analysis for H.264/AVC scalable extension (SVC) is presented. Since the dependency among layers is a major discrepancy between SVC and H.264/AVC, the hardware design about them is quite different. Therefore, we analyze the memory bandwidth and memory access requirement of different coding flows for SVC. Based on the analysis results, we deduce that the frame-level...
In this paper, a memory efficient Fine Grain Scalability (FGS) coefficient encoding method is proposed to reduce the external memory access requirement. In the H.264/AVC Scalable Video Extension, the FGS coefficients encoding is frame based. However, the frame based mechanism results in the difficulty of hardware implementation due to large internal memory requirements and external memory accesses...
