Abstract

Requiring more bandwidth at reasonable power consumption, new communication infrastructures must provide adequate solutions to guarantee performance during physical integration. In this paper, we propose the design of a low-power asynchronous Network-on-Chip which is implemented in a bottom-up approach using optimized hard-macros. This architecture is fully testable and a new design flow is proposed to overcome CAD tools limitations regarding asynchronous logic. The proposed architecture has been successfully implemented in CMOS 65nm in a complete circuit. It achieves a 550Mflit/s throughput on silicon, and exhibits 86% power reduction compared to an equivalent synchronous NoC version.
