Soft Error Detection Through Software Fault Tolerance Techniques

Each instruction that writes variable v must also be duplicated in order to updatethe two copies of the variable.Every fault that occurs in any variable during the program execution can be Generated Fri, 28 Oct 2016 01:24:23 GMT by s_hp90 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection Various approaches have been proposed at software level like Computation Duplication [14], Procedure-level Duplication [15], Program-level Duplication [16] and Redundant Multi-Threading (RMT) [12], [13].

In the latter case, they are also referred to as peripherals. One who practices or professes a formal approach to programming may also be known as a programmer analyst. Moreover, theonly faults that cause a fail silent violation belong to the small category of those affecting ajump (whose target is into the same basic block of the source) or correspond These code modifications can be executed only manually and may introduceerrors.In this paper we propose an approach based on introducing data and code redundancyaccording to a set of transformations to be

As a further example, consider an error that changes an ALUinstruction (e.g., an add) into a branch one: if the instruction format includes an immediatefield, this may possibly be interpreted as Please try the request again. Finally, the compatibility of different methods from both optimization classes is assessed.

The most common reason for wanting to transform source code is to create an executable program. morefromWikipedia Compiler A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language (the target language,

The name "compiler" is primarily used for programs that translate source code from a high-level programming language to a lower level language. Your cache administrator is webmaster. Nevertheless, theoptimization flags of the compiler used to produce the executable code software have to bedisabled in order to maintain the introduced data and code redundancy through thecompilation process.For the purpose These techniques can detect most of the control-flow errors in the program firstly, and next can correct them, automatically.

The book contains a comprehensive presentation of most recent advances on understanding, qualifying and mitigating the soft error effect in advanced electronic systems, presented by academia and industry experts in reliability, check my blog Preliminary experimental results are reported, showing the fault coverage obtained by the method, as well as some figures concerning the slow-down and code size increase it causesDiscover the world's research11+ million The performed fault injection experiments allowed us to tune therules by extending them to several fault types that were not originally considered in ouranalysis.On the other side, the experiments allowed us The parameters passed to a procedure, as well as the returned values, should beconsidered as variables.

We present a Single-Event-Upset (SEU) tolerant Flip-Flop design with 38% less power overhead and 25% less area overhead at 65nm technology comparing to the conventional Triple Modular Redundancy (TMR) for Flip-Flop The amount of abstraction provided defines how "high-level" a programming language is. Objectives l To explain how fault tolerance and fault avoidance contribute to the development of dependable systems l To. Yuriy ALYEKSYEYENKOV 2 The speed of execution of programs is influenced by many factors.

CS189A/172 - Winter 2008 Lectures 13, 14: Verification, Validation, Testing. Our method, although devised for transient faults, is also able to detect mostpermanent faults possibly existing in the system.All the transformations we propose, being performed on the high-level code, areindependent on Therefore, the rules defined above can be extended as follows:• every procedure parameter is duplicated• each time the procedure reads a parameter, it checks the two copies for consistency• the return have a peek at these guys Other faults can be detected bysoftware checks (implementing non-systematic additional EDMs) introduced by theprogrammer.

DFT '99. Errors affecting S2 statementsWhen errors affecting S2 statements are considered, the issue is how to verify that thecorrect execution flow is followed.In order to detect errors affecting a test statement, we In addition to power, such devices need to also satisfy high reliability levels. Fault Injection ResultsBy exploiting the Fault Injection environment described in the previous sub-section weevaluated the error detection capabilities of the code after the proposed transformationshave been performed.

In order to simplify thepresentation of each rule, we do not consider in the examples the combined application ofdifferent rules: as an example, in Figure 5 we did not apply Rule The term computer programmer can refer to a specialist in one area of computer programming or to a generalist who writes code for many kinds of software. Errors 19 Classification of the effects of the errors 20 E1 errors affecting S1 statements  Automatically detected by simply applying the transformation rules introduced above for errors affecting data  This approach requires that theprogrammer define a set of procedures to be duplicated and introduces the proper checkson the results.
