<p><b>Abstract</b>—For a reconfigurable architecture, the harvest rate is the expected percentage of defect-free processors that can be connected into the desired topology. In this paper, we give an analytical estimation for the harvest rate of reconfigurable multipipelines based on the following model: There are <it>n</it> pipelines each with <it>m</it> stages, where each stage of a pipeline is defective with identical independent probability 0.5 and spare wires are provided for reconfiguration. By formulating the "shifting" reconfiguration as weighted chains in a partial ordered set, we prove when <it>n</it> = Θ(<it>m</it>), the harvest rate is between 34% and 72%.</p>
