Fault and EnergyAware Communication Mapping with Guaranteed Latency for Applications Implemented on NoC
42nd Design Automation Conference, Anaheim, CA, June 13-17, 2005, pp. 266-269
As feature sizes shrink, transient failures of on-chip network links become a critical problem. At the same time, many applications require guarantees on bo th message arrival probability and response time. We address the problem of transient link failures by means of temporally and spatially redundant transmiss ion of messages, such that designer-imposed message arrival probabilities are guaranteed. Response time minimisation is achieved by a heuristic that statica lly assigns multiple copies of each message to network links, intelligently combining temporal and spatial redundancy. Concerns regarding energy consumption are addressed in two ways. Firstly, we reduce the total amount of transmitted messages, and, secondly, we minimise the application response time such that the resulted time slack can be exploited for energy savings through voltage reduction. The advantages of the proposed approach are guaranteed message arriva l probability and guaranteed worst case application response time.
