Question

We want to use a ROM memory to implement a digital circuit that receives two 2-bit numbers X and Y (X=x1x0, Y=y1y0) and detects whether X is greater (G=1), lower (L=1) or equal (E=1) to Y. What information must be stored in the memory address words 0101 and 1100?

Note: The most significant bit of the address bus is x1.
