binary mutiplier & divider

[4electros]

hello, these are the algorithms of multiplying and dividing for two binary numbers with their corresponding implmentaion figures , well i actually understood the algorithms but still not getting into implementation yet..
I need help to get through, thanks.

What difficulties are you having?

FA means "full adder", so the multiplier is just an addition network using ripple carries. The multiplication by 0 or 1 is provided by the AND gates.

The division circuit is only one bit of the entire divide process. I assume it can be cascaded somewhat like the full adders of the multiplier circuit to create a combinatorial divider, or attached to registers driven by a sequencer.

May I ask if I have a keypad to input the BCD, how shld I implement using the above schematic diagram?
Do I need to convert BCD to binary?? Thanks

You will need to design and build a system that takes the data from the keypad, convert it into a form that can be used by the schematics, and display or transmit the results.

If you're trying to do this without a microcontroller (hint), you will need to learn more about digital design.

Some of the components on the schematics aren't necessarily available as "off-the-shelf" items.

How do you intend to implement the posted schematics?

Hi there, I have already created a keypad matrix . I actually have completed my add/subtract calculator for my projects. I am trying to add in multiplier for bonus mark .
I supposed I have to convert BCD values to binary first. Go through the multiplier cct and then convert back to BCD values and stored back to register
