A Fault Tolerant SRAM Using Reed Solomon Codes and Bulk BICS
نویسندگان
چکیده
The present work contains information about the design and implementation of a SRAM memory that is able to cope with SEU and SET produced by radiation. This paper shows how two different techniques could be implemented together to aim that target. The architecture of the memory is proposed, and details of the different blocks are given. Also a new method is developed and proposed for automatic recovery of the data after a SEU. Making use of the proposed topics, an ASIC will be produced for diagnose and compare of the methods involved in the design.

A general construction of Reed-Solomon codes based on generalized discrete Fourier transform
In this paper, we employ the concept of the Generalized Discrete Fourier Transform, which in turn relies on the Hasse derivative of polynomials, to give a general construction of Reed-Solomon codes over Galois fields of characteristic not necessarily co-prime with the length of the code. The constructed linear codes enjoy nice algebraic properties just as the classic one.
متن کاملOptimizing Cauchy Reed-Solomon Codes for Fault-Tolerant Storage Applications
In the past few years, all manner of storage systems, ranging from disk array systems to distributed and widearea systems, have started to grapple with the reality of tolerating multiple simultaneous failures of storage nodes. Unlike the single failure case, which is optimally handled with RAID Level-5 parity, the multiple failure case is more difficult because optimal general purpose strategie...
متن کاملFault-tolerant conversion between adjacent Reed–Muller quantum codes based on gauge fixing
We design forward and backward fault-tolerant conversion circuits, which convert between the Steane code and the 15-qubit Reed–Muller quantum code so as to provide a universal transversal gate set. In our method, only seven out of a total 14 code stabilizers need to be measured, and we further enhance the circuit by simplifying some stabilizers; thus, we need only to measure eight weight-4 stab...

متن کاملHybrid Approaches for Distributed Storage Systems
Distributed or peer-to-peer storage solutions rely on the introduction of redundant data to be fault-tolerant and to achieve high reliability. One way to introduce redundancy is by simple replication. This strategy allows an easy and fast access to data, and a good bandwidth efficiency to repair the missing redundancy when a peer leaves or fails in high churn systems. However, it is known that ...
