Hey Everyone,
I want to design an 8-bit Multiplier, using 4-bit Adders. I created a Ripple Carry Multiplier using 16 4-bit adders, but after debugging realized it doesn't work. I got this schematic off of a 4-bit multiplier i saw online, but can't find the link to it anymore.
Here is the schematic I created:
SUMMARY HOW IT WORKS:
Mantissa 1 (A7-A0) go into A7-A0 of each ADDER stage.
Mantissa 2 (B7-B0) go into the CI of each ADDER stage.
0’s go into the first stage of B7-B0, to initialize it.
The output of each stage (X7-X0) go into the input of next stage (B7-B0).
The results (P7-P0) are on the CO of each stage, and the outputs of the last stage (X7-X0) are P15-P8.
If someone could please help me correct it or see any mistakes or know of any another way to create an 8-bit multiplier using 4-bit adders. Thank you for your time and help!
