Hi, Have you had a look at the new FMC standard (VITA 57)? It looks extremely promising as nowadays many designs are based on a simple FPGA with variations on the front pannel. Sofar I have only seen FMC developments for high perfomance plataforms based on Virtex5, but I feel that a great benefit would appear when using a flexible low budget carrier with flexible low cost front pannels. Check this article for quick intro to VITA 57 http://www.vmecritical.com/articles/id/?3575 What do you think? Cheers pablo

> Are you nym-shifting?I just change my mind while creating my profile. It seems that there is some the alias update had a latency of some minutes. In any case I am very interested in knowing your opinions about FMC, and specially in its use with low cost FPGAs. Cheers pablo

Many manufacturers already have proprietary mezzanine cards for doing exactly this. At Alacron, we use both standard and proprietary mezzanines. For example we use the "user defined" fourth connector of PMC to connect directly to our FPGA on the base card. Some of our add-on "PMC" modules don't have the PCI bus at all and just use this fourth connector. On some of our newer boards we have proprietary mezzanines using high-speed connectors to add various font-end interfaces like analog VGA input or Camera Link. I imagine using a standard for these front-end cards would allow us to add third-party modules to quickly add more front-end interfaces. Of course this all depends on the details, which are not in the article. Regards, Gabor

Is Vita-57 an approved standard? Here's an alternative that has been in use for more than 2 years: www.em.avnet.com/exp. It was developed and is now used by Avnet for FPGA development boards and expansion modules, but the specification is public for anyone to use. nic On Nov 25, 6:33=A0am, Gabor <ga...@alacron.com> wrote:> On Nov 24, 11:34=A0am, palvarez <pabloalvarezsanc...@gmail.com> wrote: > > > > > > > Hi, > > > Have you had a look at the new FMC standard (VITA 57)?

I do not know what is wrong with it.John Doe is a troll. Ignore him. I plonked him long ago. Your post is on-topic and valuable. Thanks for the heads up. Mike Monett

However, I've been trying to get the proper spec from VITA for ages but it hasn't been formerly released yet. Presumably VMETRO & Xilinx are VITA members and have a pre-release. Colin

I have also tried to get it this week but there is an unusual delay.. Cheers pablo
