Fault-tolerant Routing for Irregular Faulty Patterns in 2D-Mesh without Virtual Channel

Abstract

In wormhole meshes, many fault-tolerant routing algorithms have been proposed. None of them, however, can tolerate general (irregular) fault model without virtual channels. In this paper, a 0-virtual channel fault-tolerant deadlock-free routing algorithm for general fault model is proposed for wormhole routing in two-dimensional meshes.
