摘要: 对非对称交叉开关的吞吐率进行了理论分析和模拟测试,得出非对称交叉开关中排头兵效应的影响非常弱,几乎可以忽略.在此基础上,提出了一种基于非对称交叉开关的高阶路由器交换结构,即层次式非对称交叉开关结构设计方法,同时,给出了该交换结构的瓦片化微结构.结果表明,该结构可以获得很高的吞吐率.

关键词: 高阶路由器, 非对称交叉开关, 吞吐率

Abstract: Throughput of asymmetric crossbaris was analyzed in theoretical and simulation way. The result reveals that in asymmetric crossbar head of line (HOL) effect can be negligible. A new architecture of high radix router, hierarchical asymmetric crossbar (HAC), which is based on asymmetric crossbar, along with its tile-based microarchitecture, was introduced. The simulation reveals that HAC router can get much high throughput.

Key words: high radix router, asymmetric crossbar, throughput
