1- (Odd/Even number) Design a hardware circuit that distinguishes between the 8-bit input odd and even number. If the input number is even the first LED should be ON otherwise, the second one should be ON.

2- Design a combinational digital circuit in HLS that finds the pattern of 1011 in a 9-bit binary input. It should return 1 if can find the pattern and 0 otherwise.

3- Gray code is an ordering of binary numbers in which two adjacent values differ only in one bit. It is widely used in electromechanical switches. The following table shows the 4-bit Gray code for the numbers between 0 and 15.
