Abstract
With the advance of the semiconductor technology, a huge number of transistors are available on a single chip. This advance allows System-on-chip (SoC) designers to put a lot of intellectual property (IP) blocks in a chip. However, the inter-communication between IP cores becomes main challenge of SoC design. In order to overcome the problem, Network-on-chip (NoC) has been proposed to provide a scalable and reliable on-chip infrastructure in recent years. The high performance design is one of the most important issues to Network-on-chip design and the implementation of scalable communication structures. In this thesis, we propose a Single Router Output Port Selection Mechanism (SROPS) for reducing the packets contention for output ports in a 2D mesh NoC router. By calculating the congestion probability of routing selection in a router, SROPS can choose an appropriate output port for the incoming packets. Experiments show that SROPS, when compared with oe-fixed mechanism, improve the saturation point by 68.97% at the scarification of area increase by 2.3%. Also, among others proposed mechanisms (e.g., BL, turn1, turn), this proposed one increase the saturation point performance by 27.15%, 20.82%, and 19.72% respectively.
