Doing Complete calculator in vhdl wont turn out to be economical design.
What you can do is you need to write / use some 8 bit vhdl CPU to do the job.
Using this cpu you can interface keyboard and display to it. And use it for doing
calculations also. 8051 core in vhdl is available you can use it. For testing you

I was thinking of building a hardware using vhdl which will transfer between the Camera's serial port to Ethernet (and the opposite of course).
Does anyone know where I could find such code?

you could create a memory with the values of the text file, generate it through IP wizard and read it. Every time that you want to read a image you have to modify your memory and recompile the entire project. This is like and "offline" solution.

some issues are apparent:
1.) rs232 is lsb first, so "z" will come up as 0 0101 1110 1.
2.) you appear to transmit "M" lsb first (correct), but the start/stop bits are swapped (incorrect). eg, x1(0) = '1' and x1(9) = '0'. Thus the framing will be incorrect. the receiver may see 11001001 as the data byte, which would be an extended ascii charac

Using a LED as output, and acting on a digital input is the most basic application you could implement.
If you are looking for some 'communication' with the outside world, then a rs232 interface is probably one of the easiest to implement (both in software and hardware).
