Question

The amount of ROM needed to implement a 4 bit multiplier is?

Answer 1

To calculate amount needed we use the following formula:

`2^(a) \cdot b`
Where a - number of input bits
b - number of output bits
In this case we have:

`2^(4) \cdot 2^(4) = 2^(8) = 256` input bits
The number of output bits would be 8.

`256 \cdot 8 = 2048`
