Abstract :
A systolic array design for the algebraic path problem (APP) is presented that is both simpler and more efficient than previously proposed configurations. This array uses N2 orthogonally connected processing elements and requires 2N I/O connections. Total computation time is 5N-2, which is the minimum time possible in a systolic implementation. The data pipelining rate is one, so no pipeline interleave is required. For multiple problem instances a block pipeline rate of N can be achieved, which is optimal for an array of N2 processing elements
