i have this mini project can anyone solve it to me

Write the VHDL code for the ALU that takes two inputs A and B and performs the
following operations depending on the values of the control signal C:
Each signal A and B is 16-Bit Wide.​
Arithmetic Operations​
:​

Control Signals and Operations​
0000 A Plus B
0001 Increment A by 2
0010 A Minus B
0011 Decrement A by 3​
Comparison Operations​
Control Signals and Operations​
0100 Minimum of A and B
0101 Maximum of A and B
0110 A AND B
0111 A OR B​
Shift Operations​
Control Signals and Operations​
1000 Circular right shift of A
1001 Circular left shift of A
1010 Right shift of A with feed in 0
1011 Left shift of A with feed in 0
1100 Right shift of A with MSB replication​
1101 Left shift of A with LSB replication

- MSB stands for the most significant bit.
- LSB stands for the least significant bit.
- Circulate means rotate.
- You can use the Relational Operations in your code (<, >, >=, <=, =, /=)
