In this paper, a simple but efficient reconfiguration algorithm and placement algorithm are proposed to enhance the manufacturing yield of WSI array processors at low performance degradation. The low performance degradation is significant for high-performance WSI arrays. The objective of our reconfiguration strategy is to achieve better utilization of good spares, while also ensuring that the restructured inter-PE communication links do not become so long as to significantly degrade the performance. Monte Carlo simulation is performed to estimate the array yield and to obtain the performance degradation probability distribution for fault patterns with both PE and switch faults. The simulations conducted indicate that the computational time of the algorithms is quite low, therefore the proposed scheme may also be very suitable for certain run-time fault tolerance.
