Checker Backend for Soft and Timing Error Detection and Recovery
نویسنده
چکیده
Current microprocessors are becoming more vulnerable to cosmic particle strikes and parameter variations. Particle strikes may cause soft (transient) errors, whereas high variability (due to process, temperature and voltage) may transform non-critical paths into critical paths, resulting in timing errors. This paper proposes a design that exploits the benefits of clustering for detecting and recovering from soft and timing errors in the backend. We propose to use some of the regular backend-clusters for error detection and correction, which would work as a checker backend(s).

متن کاملJoint Timing Recovery and Turbo Equalization for Coded Partial Response Channels
We propose a method for jointly performing timing recovery and turbo equalization on partial response channels with error-correction codes. The proposed detector uses soft decisions from previous turbo iterations to improve timing estimates before the next, and each iteration is only marginally more complex than that of a conventional turbo equalizer. As compared to a conventional receiver with...
متن کاملComplexity Reduction of Modified Per-Survivor Iterative Timing Recovery for Partial Response Channels
The problem of timing recovery operating at low signal-to-noise ratio has been recently solved by a modified per-survivor iterative timing recovery (MPS-ITR) proposed in [1], which jointly performs timing recovery, equalization, and error-correction decoding. In practice, this scheme exploits a splitpreamble strategy in conjunction with a per-survivor soft-output Viterbi algorithm equalizer to ...
متن کاملExtending a Compiler Backend for Complete Memory Error Detection
Technological advances drive hardware to ever smaller feature sizes, causing devices to become more vulnerable to faults. Applications can be protected against errors resulting from faults by adding error detection and recovery measures in software. This is popularly achieved by applying automatic program transformations. However, transformations applied to intermediate program representations ...
متن کاملFalse Error Vulnerability Study of On-line Soft Error Detection Mechanisms
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the D...
