Title
Architecture and synthesis for on-chip multicycle communication
Abstract
For multigigahertz designs in nanometer technologies, data transfers on global interconnects take multiple clock cycles. In this paper, we propose a regular distributed register (RDR) microarchitecture, which offers high regularity and direct support of multicycle on-chip communication. The RDR microarchitecture divides the entire chip into an array of islands so that all local computation and communication within an island can be performed in a single clock cycle. Each island contains a cluster of computational elements, local registers, and a local controller. On top of the RDR microarchitecture, novel layout-driven architectural synthesis algorithms have been developed for multicycle communication, including scheduling-driven placement, placement-driven simultaneous scheduling with rebinding, and distributed control generation, etc. The experimentation on a number of real-life examples demonstrates promising results. For data flow intensive examples, we obtain a 44% improvement on average in terms of the clock period and a 37% improvement on average in terms of the final latency, over the traditional flow. For designs with control flow, our approach achieves a 28% clock-period reduction and a 23% latency reduction on average.
