Link-sharing method of buffer in direct-connection network

Abstract

In this paper, we propose the sharing method that shares a memory between some physical link by using the multi port memory in wormhole router for NoC(Network on Chip) as efficient usage of the flit buffers. If the proposed method is implemented by conventional method, hardware cost increase greatly. Therefore, we implement proposed method by using two methods that a memory is shared by block size and a memory is controlled by list structure. In this paper, we show the effectivity of proposed method by simple estimation of hardware cost and evaluation of communication performance by software simulation.
