The paper describes a two's complement division method that automatically rounds the quotient to the nearest upper integer number. Initially, the dividend is corrected by adding one half of a divisor to the dividend. A simple non-restoring recursive process is used to obtain the bits of the quotient, one bit at a time. Quotient-overflow can be determined with some simple tests at the beginning of the division process. Two hardware implementations of this algorithm are given: one a combinational logic circuit that performs the division in simple ALU devices, and another in state controller within a XILINX XC3090 device.Jerry J. Cupal is the Associate Professor at the University of Wyoming.
