In designing heterogeneous architecture based application-specific network-on-chips (NoCs), the opportunities of performance improvement would be expanded when applying asynchronous on-chip communication protocol. This is because the wire latency can be configured independently considering the wirelength of each link. In this paper, we develop a delay model of link-wirelength in asynchronous NoC and propose a simulated annealing (SA)-based floorplan-aware topology generation algorithm to optimize link-wirelengths. Incorporating the generated topology and the associated latency values across all links, we evaluate the performance using the floorplan-annotated sdf (standard delay format) file and RTL-synthesized gate-level netlist. Compared to the TopGen, one of the general topology generation algorithms, the experimental results show that the average reduction in latency by 13.7% and in execution time by 11.8% on four applications.
