lookup table help..

amilcar is right. You have to understand the basic concepts of programmable logic hardware description languages to to start with your application problem.

Your problem description is rather vague. I don't e.g. see, how a lookup table is related to "saving the data". Saving which to data to what? "Call to lcd display" - Which kind of lcd display, which representation of data?

In my opinion, programmable logic is not the first choice for sending data to a display, although it's possible of course. Altera development kit examples are mostly using a software processor (Nios II) to perform similar tasks. Lookup tables are easily achieved by a FPGA internal ROM.
