| 摘 要： | 随着集成电路制作工艺的进步,多核与众核系统是片上系统的发展趋势.传统的二维网格(2D-mesh)型拓扑结构通信效率低、功耗高和时延长等缺点变得越来越明显.本文首先分析对比了几种常用拓扑结构在多核与众核情况下的性能,进而采用布线复杂度较低、性能较好的蝴蝶型胖树(BFT)拓扑结构来解决片上系统的设计和测试问题.随后,本文针...

| Abstract: | As the advances in integrated circuit technology,what multi-core and many-core are used on system-on-chip will be a trend.The shortcomings such as inefficient communication,high power consumption and long delay in the traditional two-dimensional grid(2D-mesh) topology will become clearly.In this paper,firstly we analyze and compare the performance about several commonly used topologies in multi-core and many-core.After that,we employ butterfly-fat tree(BFT) topology which has lower routing complexity and be... |
