A systolic array solution for the assignment problem

A systolic array for the solution of the assignment problem is presented. The algorithm requires O(n2) time and an orthogonally connected array of (n+2)*(n+2) cells consisting of simple adders and control logic. The design is area-efficient and incorporates the new concept of a Systolic Control Ring (SCR) to generate the necessary systolic wavefronts in any orientation within the design, while special cells are positioned only on the periphery of the design. The resulting Assignment Problem Iteration (API) is suitable for Wafer Scale integration using only single input and output for data permitting low bandwidth
