| Summary: | 碩士 === 國立交通大學 === 電信工程系所 === 94 === Recent research has proposed using streaming architecture to provide a leap in media applications that are poorly matched to conventional processor architecture. Besides, low power considerations are becoming an important issue for mobile systems, but streaming architecture solutions do not fit in above requirements. Therefore, in this research, a combination of media streaming architecture and low power circuitry design methodology is proposed. An ALU Cluster design for media streaming architecture is presented in this thesis, which is based on Stanford Imagine stream architecture with the consideration of implementation feasibility. The back-end simulation results decide the final micro-architecture of each component, and utilize communication bandwidth hierarchy design to effectively solve the problem of scarce memory bandwidth. The experimental results show that the power and energy consumption of selected benchmark for multimedia and baseband communication systems become scalable by dynamic selecting the number of utilized ALU Clusters. Thus, the instant performance and energy consumption of an entire work can be optimized for mobile systems. The proposed design has provided a breakthrough for similar architectures.
