A multicycle communication architecture and synthesis flow for Global interconnect Resource Sharing
In deep submicron technology, wire delay is no longer negligible and is gradually dominating the system latency. Some state-of-the-art architectural synthesis flows adopt the distributed register (DR) architecture to cope with this increasing latency. The DR architecture, though allows multicycle communication, introduces extra overhead on interconnect resource. In this paper, we propose the Regular Distributed Register - Global Resource Sharing (RDR-GRS) architecture to enable global sharing of interconnects and registers. Based on the RDR-GRS architecture, we further define the channel and register allocation problem as a path scheduling problem of data transfers. A formal and flexible formulation of this problem is then presented and optimally solved by Integer Linear Programming (ILP). Experimental results show that RDR-GRS/ILP can averagely reduce 58% wires and 35% registers compared to the previous work.
