design of a simple calculator using VHDL code

[susheelcpanguluri]

Hii friends, this site is very useful for the students and this is the first time I am posting and please make me happy.......

For your design project you will be creating a simple calculator. The calculator has a keypad as its input. The keypad has the decimal numbers 0 – 9, clear,=, + and -. You will only be implementing addition and subtraction. The following restrictions are given. The results will remain in memory until the clear button is pressed. For example you can enter
in 1 + 3 = 4 + 2 = 6. You can add on to the result like a calculator. The output must use a
form of decimal number (BCD, 2 out of 5, excess 3, etc.)
I need state machine and data path

Take all the numbers 0 – 9, and clear,=, + and - etc as inputs. Instantiate a RAM so that whatever calculations you are doing will be stored in it. Program in such a way that when you press " clear", the RAM gets erased. All the Best
