The algorithm discussed in this paper was applied for an efficient Multiplier design. Nirmal kumar, T. absolute value, add and subtract etc. This design achieves a 72MHz clock rate on an XC4036xla-9 FPGA and 170MHz clock rate on an XV300epq240-8 FPGA. Chapter 3 —Arithmetic for Computers —16 Division Check for 0 divisor Long division approach If divisor ≤ dividend bits 1 bit in quotient, subtract Otherwise 0 bit in quotient, bring down next dividend bit Restoring division Do the subtract, and if remainder goes < 0, add divisor back Signed division.
