How to construct a circuit that will multiply two 8-bit signed binary integers in two's complement format, producing a 16-bit signed result.
I can only use the basic logic gates, multiplexers, flip-flops, registers.

Thanks for the link, but I need a detailed circuit.......I can multiply it using pen and paper but not able to build a circuit with the above specifications..

 

I 'm afraid you won't get a ready-made answer here in AAC. You must work to get it.

I suggest building a block diagram for the 2's complement multiplier. Take into account the suggestion the link makes about multiplication of numbers with different signs.

Post the block diagram and more help will be on the way.

 

study the link, it specifies quite well what you need to do in terms of the circuit. And you will get help if you post an attempted solution
