Design of Priority Based Reconfigurable Router in Network on Chip

Abstract

Network on Chip (NoC) is an advanced integration design for communication networks while providing a solution to the traditional bus based System on Chip designs (SoC) too. A router is a key component which is considered as the backbone of communication in NoC. The objective of this work is to design a priority based reconfigurable router for NoC. Initially, a 4x4 Baseline router is designed and synthesised and then the channels inside the router are modified to achieve reconfiguration to improve the router's efficiency. In 4x4 Reconfigurable Router the slots are well utilized but prioritization portion is not considered. Routers are associated with switches to take data transfer decisions resulting in high power consumption. In order to overcome this problem, a new priority based reconfigurable router is designed. The design for this router is carried out using Verilog HDL and synthesized and simulated using Xilinx ISE Design Suite 14.3 and ModelSim-Altera 6.5b Software respectively. The corresponding results in terms of power, energy efficiency, area and delay are analysed and the proposed work gives better results than the conventional Baseline Router. Dizajn prioritetno nastavljivega usmerjevalnika v omrežju na čipuIzvleček: Omrežkje na čipu (NoC) je napredna integracija komunikacijskih omrežij z uporabo tradicionalnih sitemov na čipu na osnovi vodil (SoC). Usmerjevalnik predstavlja ključno komponento v komunikaciji preko NoC. Namen dela je razvoj prioritetno nastavljivega usmerjevalnika za NoC. V osnovi je uporabljen 4x4 usmerjevalnik, v kateremu so, za doseganje učinkovitosti, kanali naknadno razširjeni.Reže v nastavljivem usmerjevalniku so dobro uporabljene, vendar ne upoštevajo prioritet. Usmerjevalniki so povezani s stikali za prenos podatkov, ki imajo visoko porabo. Nastavljivi usmrjevalniku rešujejo problem visoke porabe. Dizajn usmerjevalnika je realiziran v Verilog HDL okolju in simuliran z Xilinx ISE Design Suite 14.3 in ModelSim-Altera 5.5b programsko opremo. Rezultati izkazujejo boljšo učinkovitost, nižjo porabo in zakasnitev predlaganega usmerjevalnika.
