3.1 Introduction
This chapter focuses on the architectural design of wormhole and virtual channel (VC) routers for NoC. The salient contributions of this chapter are as follows:
1. To support globally asynchronous locally synchronous style of communication, a gray counter-based dual-clock first-in first-out (FIFO) has been designed and used in NoC router.
2. Design of wormhole router for mesh-of-tree (MoT) topology has been described in detail.
3. To mitigate the head-of-line (HoL) blocking problem of wormhole router-based network, VC router has also been implemented.
The rest of the chapter is organized as follows: Section 3.2 describes the switching technique and packet format of 4 × 4 MoT-based ...
