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

To calculate amount needed we use the following formula:[tex] 2^{a} \cdot b [/tex]Where a - number of input bitsb - number of output bitsIn this case we have:[tex] 2^{4} \cdot 2^{4} = 2^{8} = 256 [/tex] input bitsThe number of output bits would be 8.[tex] 256 \cdot 8 = 2048 [/tex]
