[DIGITAL DESIGN]

It is not mandatory to use 74ls283 and 74ls194, but I have to use registers and adders so I can shift the bits and add at the end.

I already have two ideas, but they are too long.


thanks for your inputs

[DIGITAL DESIGN]

I want to design a 4-bit unsigned binary multiplier. This circuit should be accepting two 4-bit numbers and compute an 8-bit product. The result is to be displayed on two 7-segment display units.
The multiplier should be started with a RESET signal.
A READY output is to indicate the end of the operation. I want to use three registers (74ls194) and one 4-bit full adder (74ls283) for the circuit, but I'm little confused about the control unit

I wanted to use TTL only, but any idea is welcomed.
All my ideas are too long and I was wondering if anyone know easiest way around.

I don't mind using any components
