Abstract :
This paper presents an efficient binomial IP mapping and optimization algorithm (BMAP) to reduce the hardware cost of on-chip network (OCN) infrastructure. The complexity of BMAP is O(N2log(N)). Based on our OCN system synthesis flow, the proposed algorithm provides more economic network component mapping in comparison with traditional OCN mapping algorithm. The experimental result shows total traffic on network is reduced by 37% and average network hop count is reduced by 46%. With further optimization, the hardware efficiency is enhanced therefore the total hardware cost of network infrastructure is reduced to 51%~85%
