Abstract

This paper deals with the design of processor arrays for regular algorithms. The design is constrained by limited implementation cost characterizing a reconfigurable architecture. The objective of the design is to minimize the latency of the processor array. The presented approach to determine a scheduling function leading to the minimal latency of the processor array is formulated as a linear program that incorporates 1) the selection of modules to be implemented in processors to execute operations of the algorithm, 2) the binding of operations to modules, 3) the computation of the number of registers, 4) the limitation of implementation cost for modules and registers, 5) the determination of the size of partitions that allows to match the limited implementation cost.
