Abstract

Linear programming techniques are useful in many diverse applications such as: production planning, energy distribution etc. To find an optimal solution of the linear programming problem, we have to repeat computations and it takes a lot of processing time. For high speed computation of linear programming, special purpose hardware has been sought. This paper proposes a systolic array for solving linear programming problems using the revised simplex method which is a typical algorithm of linear programming. This paper also proposes a modified systolic array that can solve linear programming problems whose sizes are very large. key words: parallel processing, systolic arrays, special-purpose hardware, linear programming, revised simplex method Shinhaeng Lee received the B.S. degree in Electrical Engineering from Hongik University, Korea, in 1995. He is currently an M.S. Candidate in Electric Communication Engineering, Tohoku University, Japan.
