How many logic blocks are required to create a 4to16 decoder

How many logic blocks are required to create a 4-to-16 decoder? Give the contents of the LUTs in the first logic block.

Solution

a)The figure provided in the textbook is for building blocks of an Field Programmable Gate Array.

The required number of logic blocks is 8 because 4-to-16 decoder requires 16 outputs and each function requires atmost 4 variables.

Thus the required blocks to implement 4-to-16 decoder is 8.
