| Abstract: | The paper presents a method of high-efficient and low-cost CAVLC decoder to H.264/AVC standard. Several complex modules are optimized in arithmetic and architecture. The hardware resources are cot and the complexity of realizing the design is reduced through these methods. The result shows that the decoder can decode the coded stream of transform coefficients in each block. Moreover, it can decode one syntax element in one clock cycle, which means that it can satisfy the demand of real time decode in H.264/AVC standard. |
