摘要: There is a growing realization that the expected fault rates and energy dissipation stemming from increases in CMOS integration will lead to abandonment of traditional system reliability favor approaches offer hardware-induced errors across application, runtime support, architecture, device integrated-circuit (IC) layers. Commercial stakeholders multimedia stream processing (MSP) applications, such as information retrieval, mining systems, high-throughput image video systems already feel strain inadequate system-level scaling robustness under always-increasing user demand. While applications can tolerate certain imprecision their results, today's MSP do not support systematic way exploit this aspect for cross-layer resilience. However, research currently emerging attempts utilize error-tolerant nature purpose. This achieved by modifications all layers stack, algorithms software architecture layer, even IC digital logic synthesis itself. Unlike conventional aims worst-case performance accuracy guarantees, provide guarantees accuracy. In paper we review recent advances field an (layer-by-layer) perspective, attempt foresee some components future design may influence general computing landscape within next ten years.
