1. What device does the following VHDL code represent?
2. (a) Write a VHDL module for a LUT with four inputs and three outputs. The 3-bit output should be a binary number equal to the number of 1's in the LUT input.
(b) Write a VHDL module for a circuit that counts the number of 1's in a 12-bit number. Use three of the modules from (a) along with overloaded addition operators.
(c) Simulate your code and test if for the following data inputs:
