Process-Variation Aware Mapping of Real-Time Streaming Applications to MPSoCs for Improved Yield

Free registration required

Executive Summary

As technology scales, the impact of process variation on the MAXimum supported Frequency (FMAX) of individual cores in a MPSoC becomes more pronounced. Task allocation without variation-aware performance analysis can result in a significant loss in yield, defined as the number of manufactured chips satisfying the application timing requirement. The authors propose variation-aware task allocation for real-time streaming applications modeled as task graphs. Their solutions are primarily based on the throughput requirement, which is the most important timing requirement in many real-time streaming applications.
