can use bram for VGA

there is no sparton-2 to my knowledge. in spartan-2 you can use BRAM for any purpose, including VGA.

fahadislam, it is about time you grew up and stopped using these insane punctutions. It would also help if you learned how to spell. Perhaps you might even learn to think, if that is not asking for too much.. This is not a childrens' playground. If you want to mix with adults, behave like an adult.

sorry for miss spell :) ... I know we can use BRAM for any purpose ..

But i wanna ask is it possible tyo accomodate Bram for VGA as minimu resolution is 640*480 and minimum 8 colors needed ... so need 30720 pixel data to store and each pixel data of 3 bits ... while BRAM i of 32 kb ... can u guide if possible ... 8

Hi .. Sorry for miss spell and any other fault if u felt on my sid .. 8) after that i will simply say that i feel we r engineers and so no here to pick sentex errors .... try to be logical .... 8) thats true that i m week in my spell ....... but i will no change my style of writing for any one... we r here to discuss idea .. so be clear and focus on concept instead of sentex ... 8) thats also true that ...i m new in that field ... so if u o seniour or on adult side ... be clear to proof ur concepts and to hel others... 8)

anyways thanks for responding ... as u r my seniour ... so again i

sorry if any fault done by me ... 8) ....... Waiting for ur logical response ....... 8

Wow Peter, why don't you just come out and say what you think?

Thanks for giving me a chuckle this morning.

After you learn to spell, you could learn to do some simple arithmetic.

How much BRAM is available in your device? Call this "A."

How much memory is needed for your frame store? Call this "B."

If B > A, then you're hosed.

-a

today i feel my mathamatics is also weak 8) ... Actually my questio

was just that is it possible by using some kind of techniques lik compression etc /// and if possible then how and by using whic techniques 8) ... thanks 8

It depends on what you want to achieve. A regular bitmapped display is out of the question since you don't have enough memory. If you need to show simple images only with large fields of the same color you could use some sort of RLE compression to dramatically reduce the memory requirements.

However, if you want to show mostly text you could create a character generator hardware. You have one memory with information about what characters you want to show and one memory with information about how the characters look.

Say that each character is 8x8 pixels large. If you want to store 256 different characters this will take 2048 bytes.

With 8x8 pixel large characters you can store up to 80x60 characters on a standard VGA sized screen. (4800 bytes)

See

By drawing characters in a clever fashion you could even include some graphics on your display. It is also possible to include colors in the characters if you increase the size of the font rom. This is basically how the graphics worked on old video game consoles such as the NES and SNES.
