Lut

Question

Hi!

I'm new to the hardware description using the tools altera, I found little information on how to implement a LUT, I found an example that uses the instruction "when" and agree to take the input value, the output will be. In another example using the memory address of the card to store the precomputed values, but still, do not know how to implement it :unsure:. I'm using the DE2 board.

Could you give me a help. Thank you in advance.:D

you can read the altera coding guiidelines on how to infer a ROM here:

or you can use the megawizard to generate you a ROM to instantiate in your own code.
