Soft Error Detection Through Software Fault Tolerance Techniques

Your cache administrator is webmaster. Fault Injection environmentThe environment we exploited for our Fault Injection experiments is the one describedin [6]. On the other side, relying on software techniques for obtainingdependability often means accepting some overhead in terms of increased size of code andreduced performance.Finally, when adopting a software approach for building Since dedicated parallel processing architectures such as GPUs have become more desirable in aerospace applications due to high computational power, GPU analysis under radiation is also discussed. check over here

We then appliedthe proposed approach by manually modifying their source code according to thepreviously introduced rules. Civera, M.

Fault Injectionis performed exploiting an ad hoc hardware device which allows monitoring the programexecution and triggering a fault injection procedure when a given point is reached. Here are the instructions how to enable JavaScript in your web browser. Theprogram also implements a simple software Error Detection Mechanism, whichconsists in verifying the correctness of each part of the expression.Tab. 1 reports the ratio between the size of the source code A.

All compiler optimizations have been disabled when compiling the modifiedcode. In this paper we categorize previous works on compiler optimizations for low power and fault tolerance.

Yuriy ALYEKSYEYENKOV 2 The speed of execution of programs is influenced by many factors. http://phabletkeyboards.com/soft-error/soft-error-trends-and-mitigation-techniques-in-memory-devices.php A basic block is asequence of statements which are always indivisibly executed (i.e., they are branch-free).The following rules are then introduced, in order to check whether all the statements inevery basic Benso, P.L. For each block a deterministic signature is computedand faults can be detected by comparing the run-time signature with a pre-computed one.In most control-flow checking techniques one of the main problems is

In this paper we present two novel radiation-hardening techniques at Gate-level. The check must be performed immediately after the readoperation in order to block the fault effect propagation. The high number of faults belonging to the Fail Silent category is mainlycomposed of faults injected in an instruction after its last execution, or in a data variablebefore writing in it,

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 causes.

On the other side, a method for automaticallytransforming the software while guaranteeing the safety of the obtained system is veryattractive, since it is compatible with the low costs and the dependability August Princeton University International.

H. We do not consider the issue of eliminating software bugs: weassume that the code is correct, and the faulty behavior is only due to transient faultsaffecting the system.In [3] it has Other transformations focus on errors affecting the code, and correspond fromone side to duplicating the code implementing each operation, and from the other to addingchecks for verifying the consistency of the 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

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 PnevmatikatosT. For thepurpose of the experiments, the adopted fault model is the single-bit flip into memorylocations. We do not make anystrict assumption neither on the cause nor on the type of the fault: without any loss ofgenerality, we can assume that an error corresponds to one or
