Question

A combinational circuit using rom that accepts a 3-bit number and outputs a binary number that is equal to square of that input number

Answer 1

Answer:

You have two possibilities:

Either you can deduce logical equation for all outputs based on inputs, optimize them, find common elements etc

OR

You can unroll multiplication and use adders. For x2, x1, x0 as inputs you will have (+ is sum ^ is and):

y0 = x0

y1 = x1 + x1 * x0

y2 = x2 + x1 ^ x1 + x2 ^ x0 + c1

y3 = x1 ^ x2 + x2 ^ x1 + c2

y4 = x2 ^ x2 + c3

y5 = c4
