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
