Abstract

We consider the implementation of multiplication and division operations on one and two dimensional mesh of processors. We develop an O(驴n) step 2-dim mesh algorithm for multiplying two n-bit numbers. The algorithm is simple and does not rely upon discrete fourier transforms. We also develop an O(n) step 1-dim mesh algorithm for dividing a 2n-bit number by an n-bit number. This algorithm appears to be quite practical.
