Description/Abstract

This paper proposes a new link for asynchronous NoC communications that is resilient to transient faults on the wires of the link without impact on the data transfer capability. Resilience to transients is achieved by exploiting the phase relationship between data symbols and a common reference symbol where the symbols are transmitted using additional wires. Detection of transient faults is performed by comparison of the data symbol and the reference symbol. We demonstrate it is possible to achieve a similar number of transitions per bit as existing delay insensitive codes, from a power consumption point of view, but achieving resilience to transient faults. The link has been synthesized and validated using 0.12 μm technology and power, area and performance are given. It has been shown that the link area cost is 409 μm2 per data bit and energy per bit is 356 fJ/bit. Latency through the link is 0.8 ns and the maximum operating frequency or throughput of the link is 1.056 GHz.
