Implementation of Low Power Multiplier for High Speed Arithmetic Applications
Abstract: In DSP and FPGA based applications power, speed and area all are important parameters and all are depend on multiplier which in turn depends on adders. So, by implementing adders we can reduce the delay. Pyramidaladders are used which uses half-adder and full-adder to increase the speed and to reduce the number of gates used in the multiplier, but delay is not decreased significantly. By using of modified half-adder and full-adder both gate count and delay is reduced normal to 16-bit multiplier. If we modify the Pyramidal adder with XNOR's and MUX instead of normal half-adder and full-adder, such pyramidal adder useless gates and delay is reduced compared normal 16-bit adder. The use of XNOR's and MUX in Pyramidal adder reduces delay, as the MUX function is only select the output among inputs. The use of such pyramidal adder in multiplier delay can be decreased greatly.
