Help pls!!! clueless about VHDL

[dirty_orifice]

Hi im trying to make a code for the following question but i am clueless as how to create the source code. Help pls........

For now,you should think first about the algorithm without the seven segment display. Think of it as a C code. you have 4 cases : A>B , B>A, A=B, otherwise. You need to write an if statement for each case. you should write something like this :
if A>B then
output <= "1010";
elsif B>A then
.
. and so on . tell me if you need more help coz I don't know what's your knowledge in VHDL.

Forget about VHDL. First of all try and work out the circuit on paper.

Then you can read a book like this Fundamentals of Digital Logic with VHDL Design with CD-ROM: Amazon.co.uk: Stephen Brown, Zvonko Vranesic: Books to help you map your circuit to VHDL.

you should always draw the circuit before writing the VHDL.

you should always draw the circuit before writing the VHDL

That's generally a good suggestion. The present problem has however one case, that can't be represented by a circuit, because it's not synthesizable. In other words, the problem refers to simulation and behavioral code only. (In my opinion, it isn't a well considered exercise)

hi
as am85 said go for algorithm first and think seven segment display later
use "A" and "B" as input (8bits) one output use "IF" statements
