Abstract
A new fault tolerant multipipeline array
architecture and its diagnosis/reconfiguration
algorithm will be presented. This multipipeline
array design methodology is characterized by
constant, fault distribution independent interstage
path lengths. Other features include a low hardware
overhead and a high survival rate when it is
compared to existing approaches.
1: Introduction
The pipeline stages of a multipipeline array are
separated from each other by interconnection
networks as shown in Fig. 1. Interconnection
networks ranging from simple feed-through
