Abstract :
On the basis of the study in Network on Chip (NoC) topologies, routing algorithm, data exchange and virtual channel technology, we design an online detection method of interconnection for 2D torus structure of NoC system in this paper. This method can detect the data errors during transmission, and identify the error results from the routing switch failure or the data transmission interconnection line failure. Then we design a sub-router based on the wormhole exchange using E-cube routing algorithm, and a check module which is suitable for the original routing node functions and work feature. Finally, we simulate the method by Verilog HDL and quartus II software. The experiment results show that the method can detect data errors caused by the router failure or interconnect failure and can locate the fault.
