The multiplier accepts two 8-bit numbers multiplicand and multiplier and results in 16-bit multiplication. The power consumption and the area of the structure are 477 w. Wire Phi0,Phi1 // 2 phase clocking wire m1,m2,m3,m4 By Mandar Raje - An 8X8 Wallace tree multiplier is to be designed using Verilog. The proposed structure reduces the delay by 30200 comparing related works and also improves the delay of the multiplier 421.
