Paper Abstract

This paper describes the VLSI implementation of a CORDIC based processor element for use in a fault-reconfigurable systolic array to compute the singular value decomposition (SVD) of a matrix. The chip implements a time redundant fault tolerance scheme, which allows processors adjacent to a faulty processor to act as computation backup during the systolic idle time. Also, processors around a fault collaborate to reroute data around the faulty processor. This form of time redundancy is attractive when tolerance to a few faults needs to be achieved with little hardware overhead.
