Hi everyone,
could someone give me the VHDL code of a generic buffer for sample rate conversion?
e.g. from 150 MHz to 200 MHz.
Hope that someone could help me.
Thanks!

Gert
 

It's somewhat unclear, what you mean with a buffer in this respect?
 

I mean a module that can translate the sample rate from 200 MHz to 150 MHz.
I have a data stream that changes every 10 ns but it is sampled at 200 MHz; I need a module that gives on output that data stream sampled at 150 MHz.
Thanx
 

Try to use a dual clock fifo. i am suer you can find it in the web or this board. Otherwise let me know! I will upload it here
 

Thank you very much Zerox100!
In the web I found only descriptions of how to use Dual-Clock FIFO megafunctions by altera, but I'd like to have VHDL code for that function, otherwise I can't really understand the behaviour of the model.
If you could upload it or post a link, I'd be really pleased!
Thank you a lot!

I saw this post very usefull and there is a code in it.
h___://www.geocities.com/deepakgeorge2000/vlsi_book/Asynch1.pdf

If this comment is usefull then press helped bottom for me!
THX,
 
Yes, it was useful. But the only code in the pdf is about a single clock FIFO while I need a dual-clock one, 'cause the concept is quite different and more complex.
 

You are right, read this one:
h___://www.sunburst-design.com/papers/CummingsSNUG2002SJ_FIFO2.pdf

Very similar to the past one but dual clock.
 

I am trying to find sample rate using Nokia Development which is Qt. This sample rate is 2KHz and i'm trying via LAN. I have tried LAN application, does anyone have tried using sample rate with Nokia Development? Coz i don't know what component do i need to use this sample rate. Is it QAudioFormat? Thank you.
