- Abstract
- The sharing method is proposed that a memory is shared between plural 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 costs will increase greatly. Therefore, sharing a memory by block size is put forward. This paper presents the outline and pipeline processing of the proposed method. The pipeline of the proposed method has two courses of the routes 1 and 2. The number of pipeline stages of route 2 is 2 stages larger than the traditional router in order to use a shared memory. But delay is concealed if the capacity of a private buffer is enough. In addition, the effectivity of proposed method is shown by simple estimation of hardware cost and evaluation result of communication performance by software simulation.
