Design $2-$bit microprocessor with three functions, addiditon, subtraction and multiplification as code of function $00,01$ and $10$ respectively.

two $2-$bit inputs and $2-$bit function selection will be used to apply operation. any time, related output to inputs, depending on the function selection inputs should be seen at the output.

for this design, you have to use several combinational designs and MSI chips like decoder and multiplexers.

Show it in a simulation

The size of implementation should be as smal as posible
