TY - JOUR T1 - Stochastic Communication: A New Paradigm for Fault-Tolerant Networks-on-Chip JF - VLSI Design Y1 - 2007 A1 - Bogdan, Paul A1 - Dumitraş A1 - Tudor A1 - Marculescu, Radu AB - As CMOS technology scales down into the deep-submicron (DSM) domain, the costs of design and verification for Systems-on-Chip (SoCs) are rapidly increasing. Relaxing the requirement of 100% correctness for devices and interconnects drastically reduces the costs of design but, at the same time, requires SoCs to be designed with some degree of system-level fault-tolerance. Towards this end, this paper introduces a novel communication paradigm for SoCs, called stochastic communication. This scheme separates communication from computation by allowing the on-chip interconnect to be designed as a reusable IP and also provides a built-in tolerance to DSM failures, without a significant performance penalty. By using this communication scheme, a large percentage of data upsets, packet losses due to buffers overflow, and severe levels of synchronization failures can be tolerated, while providing high levels of performance.
