چکیده

We provide a new definition for the concept of skew in parallel asynchronous communications introduced in [2]. The new definition extends and strengthens previously known results on skew. We give necessary and sufficient conditions for codes that can tolerate a certain amount of skew under the new definition. We also extend the results to codes that can tolerate a certain amount of skew and detect a larger amount of skew when the tolerating threshold is exceeded.

Coding for skew-tolerant parallel asynchronous communications

Consider a communication channel that consists of several subchannels transmitting simultaneously and asynchronously. As an example of this scheme, consider a board with several chips. The subchannels represent wires connecting between the chips where differences in the lengths of the wires might result in asynchronous reception. In current technology, the receiver acknowledges reception of the...

A Note on Parallel Asynchronous Channels with Arbitrary Skews

A zero-error coding scheme of asymptotic rate log 2 (1 + √ 5) − 1 was recently described in [1] for a communication channel composed of parallel asynchronous lines satisfying the so-called no switch assumption. We prove that this is in fact the highest rate attainable, i.e., the zero-error capacity of this channel.

An approach to fault detection and correction in design of systems using of Turbo ‎codes‎

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

Epm–rt–2008-10 All Digital Skew Tolerant Synchronous Interfacing Methods for High-performance Point-to-point Communication in Dsm Socs

Ce rapport technique peut-être repéré par auteur et par titre dans le catalogue de la Bibliothèque : High-performance clocking of IPs, within a skew budget, is becoming difficult in Deep Sub-Micron technologies. Therefore, the concept of local islands of independent clocks prevails in SoCs, which can communicate using various synchronous and asynchronous interfacing methodologies. However, asyn...

Commutative curvature operators over four-dimensional generalized symmetric spaces

Commutative properties of four-dimensional generalized symmetric pseudo-Riemannian manifolds were considered. Specially, in this paper, we studied Skew-Tsankov and Jacobi-Tsankov conditions in 4-dimensional pseudo-Riemannian generalized symmetric manifolds.
