4 Bit Multiplier Schematic. A 4 4 unsigned binary multiplier takes two four bit inputs and produces an output of 8 bits. Schematic of 4 4 bit multiplier using 4 bit full adders is given below.
The unconnected inputs are the combinations of the input bits anded in pairs. Schematic of 4 4 bit multiplier using 4 bit full adders is given below. Conclusion it can be concluded that the performance of the 4x4 bit vedic multiplier seems to be highly efficient interms of speed when compared to array multipliers.
We can quickly build a circuit to add two 4 bit numbers ripple carry.
The leftmost bit is the lsb bit of partial product. The exact combinations at each adder box can be found out from the verilog code. The unconnected inputs are the combinations of the input bits anded in pairs. 4 by 4 array multiplier building blocks of 4 4 array multiplier.
