A system is needed to control a 7 segment display. The input is all of the possible binary codes 0000 to 1111. The output will be a 7 segment display of the hexadecimal digits 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f. How many K-maps are needed to solve this problem?

Write VHDL code for the following: Use HEX-to-seven segment display converters to display the inputs and results for a 4-bit adder. The inputs are unsigned 4-bit binary numbers. The outcome is a 4-bit binary adder with LED display. First you need to create a symbol for the HEX-to-seven segment display converter. Then implement a 4-bit adder using VHDL. Finally, connect three HEX-to-seven segment display converters to display input X, input Y, and sum S.
