A multi-synchronous bi-directional NoC (MBiNoC) architecture with dynamic self-reconfigurable channel for the GALS infrastructure

Abstract

Abstract To enhance the performance of on-chip communications of Globally Asynchronous Locally Synchronous Systems (GALS), a dynamic reconfigurable multi-synchronous router architecture is proposed to increase network on chip (NoC) efficiency by changing the path of the communication link in the runtime traffic situation. In order to address GALS issues and bandwidth requirements, the proposed multi-synchronous bidirectional NoC’s router is developed and it guarantees higher packet consumption rate, better bandwidth utilization with lower packet delivery latency. All the input/output ports of the proposed router behave as a bi-directional ports and communicate through a novel multi-synchronous first-in first-out (FIFO) buffer. The bidirectional port is controlled by a dynamic channel control module which provides a dynamic reconfigurable channel to the router itself and associated sub-modules. This proposed multi-synchronous bidirectional router architecture is synthesized using Xilinx ISE 14.7 and FPGA Virtex 6 family device XC6VLX760 is considered as target technology and its performance is evaluated in terms of power, area and delay.Peer ReviewedPostprint (author's final draft
