Efficient soft error protection for commodity embedded microprocessors using profile information

Soft Error Modeling and Analysis for Microprocessors

Soft errors are a growing concern for processor reliability. Recent work has motivated architecture level studies of soft errors since the architecture level can mask many raw errors and architectural solutions can exploit workload knowledge. My dissertation focuses on the modeling and analysis of soft error issues at the architecture level. We start with the widely used method for estimating t...

Cost Effective Soft Error Mitigation in Microprocessors

Device scaling has caused the challenges that processor designers face to evolve significantly in the past. This trend will continue into the future, and reliability is emerging as a significant challenge. In this work, we focus on one aspect of the reliability problem: soft errors. In particular, cost effective mitigation of soft errors in processor microarchitecture. Our investigation begins ...

REESE: A Method of Soft Error Detection in Microprocessors

Future reliability of general-purpose processors (GPPs) is threatened by a combination of shrinking transistor size, higher clock rates, reduced supply voltages, and other factors. It is predicted that the occurrence of arbitrary transient faults, or soft errors, wi l l dramatically increase as these trends continue. In this papec we develop and evaluate u fault-tolerant niicroprocessor archite...

Progressive Optimal Error Protection of Embedded Codes

The embedded wavelet image coders such as SPIHT [1] or JPEG 2000 [2] allow an efficient progressive transmission of digital images. However, the bitstreams generated by these coders are very sensitive to channel noise, and error protection is necessary to ensure acceptable reconstruction fidelity. One of the most successful protection systems for embedded wavelet coders was recently proposed by...
