Juni 20005. However, the original pattern of ones and zeros cannot be reconstructed purely from this knowledge alone.

In exemplary embodiments, the arithmetic pipeline may be implemented as a fixed-point pipeline (to execute a fixed-point arithmetic instruction) or a floating-point pipeline (to execute a floating-point arithmetic instruction). This may lead to a higher speed and more efficient error correction when compared to contemporary error correction processes. J. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures.

When the parity error is correctable, the arithmetic pipeline 110 selects whichever operand is correct, and writes the result back to a target address, in both copies of the register file The control unit 104 then resumes normal operation, by re-issuing the original instruction, which caused the detection of the soft error. SWIFT: Software implemented fault tolerance[C]// Proceedings of the International Symposium on Code Generation and Optimization. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the

An exemplary sequence of events for detecting and correcting a parity error is depicted in FIG. 2. The inserted error recovery instruction replaces the corrupted data in the first register file with a copy of the data from a second register file that mirrors the first register file. For a better understanding of the invention with the advantages and features, refer to the description and to the drawings. useful reference Error detection refers to the act of ascertaining that a disturbing event has occurred, while error correction refers to the process of reproducing the original, uncorrupted data pattern.

The magnetic field is most commonly defined in terms of the Lorentz force it exerts on moving electric charges. Copyright © 2016 ACM, Inc. Exemplary embodiments are described in terms of a single instruction/multiple data (SIMD) processor, but can be applied to the generic case of any processor pipeline with duplicated register files. Technical effects and benefits include the ability to perform error recovery in a more efficient and less obtrusive manner than conventional ECC based mechanisms.

In an exemplary embodiment, state machines and recovery logic hardware in the processor handle this entire recovery operation, including the detection of the parity error, the capturing of the offending address Computer-Aided Design of Integrated Circuits and Systems, IEEE Transactions on, 2010, 29(7): 1018–1027.CrossRefGoogle Scholar[11]Jason A B, Gupta S, Feng S G, et al.

In the event of a soft error, as long as one does not occur at the same address in both copies of the register file, which is highly unlikely, the normal The control unit 104 then signals to the error recovery circuitry 116 to begin the error recovery sequence.

The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. morefromWikipedia Soft error In electronics and computing, a soft error is an error in a signal or datum which is wrong. New York: ACM Press, 2005: 118–124.Google Scholar[4]Jason A B, Gupta S, Feng S G, et al. An error recovery instruction is inserted into an arithmetic pipeline in response to detecting the corrupted data.

In an exemplary embodiment, the arithmetic unit 102 loads the data in register file 106 and register file 108, and the arithmetic pipeline 110 processes the instructions and performs arithmetic on The system returned: (22) Invalid argument The remote host or network may be down. The system also includes an arithmetic pipeline for receiving data read from the first register file, and error detection circuitry to detect whether the data read from the first register file http://phabletkeyboards.com/soft-error/soft-error-detection.php The Government has certain rights to this invention.

In an exemplary embodiment, the soft error is detected using a parity bit that detects a parity error.
