Title
Adaptive idleness distribution for non-uniform aging tolerance in multiprocessor systems-on-chip
Abstract
In deep submicron designs of Multiprocessor Systems-on-Chip (MPSoC) architectures, uncompensated within-die process variations and aging effects will lead to an increasing uncertainty and unbalancing of expected core lifetimes. In this paper we present an adaptive workload allocation strategy for run-time compensation of variations- and aging-induced unbalanced core lifetimes by means of core activity duty cycling. The proposed techniques regulates the percentage of idle time on short-expected-life cores to meet the platform lifetime target with minimum performance degradation. Experiments have been conducted on a multiprocessor simulator of a next-generation industrial MPSoC platform for multimedia applications made of a general purpose processor and programmable accelerators.
