Network-on-Chip (NoC) has become popular as a high-performance interconnect, especially in comparison with the traditional buses, which cannot transfer more than one data-stream simultaneously, are more likely to become a bottleneck. In traditional routers, each intermediate node has a buffer capable of storing a flit. But the problem of buffer deadlock occurs when the buffers are full. In this paper, the authors propose a novel data-transfer method called black-bus as a NoC and the use of First-In-First-Out (FIFO) queue. In black-bus, a local IDentifier (ID) is attached to each raw data as routing information.
