碩士 === 中原大學 === 資訊工程研究所 === 105 === The evaluation of technology makes the modern computer architecture consist of many processing cores. The mechanism of increasing core numbers of the computer system become the major orientation of design computer systems. As the number of processing cores are increased, the interconnection network for connecting these cores become the dominant factor of computer performance. Hence how to improve the performance of the interconnection network becomes the important goal of develop modern computer systems. The performance of interconnection network are affected by the connecting topology, routing mechanism, switch architecture, and the flow control mechanism. Accordingly, this study based on the Self Similar Cubic (SSC) multicore network, develops a new interconnection network, Alternative Self Similar Cubic (ASSC) by adding the inter-block alternative paths and the corresponding packet management mechanisms. The additional inter-block alternative paths can reduce the distance of transferring among foreign nodes. The packet management mechanisms can adjust the packet sending rates to avoid the potential packet congestion. This study firstly introduces the original SSC and the proposed ASSC interconnection networks, with the packet management mechanisms for ASSC network. Then the models of main components of ASSC interconnection network are discussed. The suitable routing mechanism and the packet management mechanisms are also implemented. These models and mechanisms are evaluated by using several kinds of packet patterns, to reveal the capabilities and performance enhancement. According to the experimental results, compared to original SSC network, the proposed ASSC network and the corresponding packet management mechanism can solve the packet congestion and improve the performance of the packet communication.
