Tabulate a truth table for an $8 \times 4$ ROM that implements the following four boolean functions: $A(x,y,z) = \sum (1,2,4,6)$ $B(x,y,z) = \sum (0,1,6,7)$ $C(x,y,z) = \sum (2,6)$ $D(x,y,z) = \sum (1,2,3,5,7)$

specify the size of a ROM ( Number of words and number of bits per words) that will accommodate the truth table for the following combinational circuit components: A binary multiplexer that multiplies two 4-bit numbers. A 4-bit adder-subtractor. A quadruple 2-to-1 line multiplexer with common select and enable inputs. A BCD-to-seven-segment decoder with an enable input.

A ROM is used to store the Truth table for binary multiple units that will multiply two $4-bit$ numbers. The size of the ROM (number of words $\times$ number of bits) that is required to accommodate the Truth table is $M \text{ words}\times N \text{ bits}$. Write the values of $M$ and $N$.
