Preventing Fault Tolerant in Fifo Buffer of Noc Router

V. NAVEEN KUMAR, Y.L. Ajay Kumar, S. Ravi Kumar

Abstract


The on-line transparent test technique for detection of latent hard faults which develop in first input first output buffers of routers during field operation of NoC and also propose fault tolerant solution by introducing implementation of the proposed test algorithm has been integrated into the router-channel interface and on-line test has been performed with synthetic self-similar data traffic. A prototype implementation of the proposed test algorithm has been integrated into the router-channel interface and on-line test has been performed with synthetic self-similar data traffic. The performance of the NoC after addition of the test circuit has been investigated in terms of throughput while the area overhead has been studied by synthesizing the test hardware. In addition, an on-line test technique for the routing logic has been proposed which considers utilizing the header flits of the data traffic movement in transporting the test patterns.
