'[EE]: Universal PCI boards for PC extension?'

Hi All,

Disappearance of ISA slot in modern PC's makes building of extension boards
much more complicated (In fact the new "legacy free PC" specification from
Micro$oft tends to change PC into the closed system completely useless for
hobbyist/small firm hardware development). Making of PCI board is much more
difficult (and much more expensive if we consider the price of "PCI
bridge"). However I think, that this task could be significantly simplified
by manufacturing of "programmable prototype boards".

I think it could be done with simple board containing:

1) PCI connector
2) The programmable FPGA circuit (I'd suggest Altera ACEX EP1K50FC256
  because of it's relatively low price, PCI compatible I/Os, freely
  downloadable development tools <even VHDL or Verilog>)
3) The prototyping area.
With the availability of free PCI controller core (http://www.opencores.org)
it should be relatively easy to use such prototype board for manufacturing
of PC extensions.

The only problem is that EP1K50FC256 is in BGA case so it is almost
impossible to produce such board at home :-(.

Maybe someone would like to produce such boards? Probably there wolud be
many people (hobbyist or even profesionals) interested in using it?

Check out Elector Electronic Magazine feb 01. Here they have a prototype board for the PCI-bus. This seems to be what you're looking for....

Perhaps Altera ought to be persuaded that it would be good for their
sales if they produced a PCI developmement board for their device?

Unless you need really high speed, I would go for a USB connection instead.
There are cheap programmable chips available that can do regular speed USB.
Microchip has PICs already that can do low speed USB and will be coming out
with regular speed USB PICs.  Others already have regular speed USB
microcontrollers.

   Even if you need high speed, USB is a good choice.  High-speed
   USB can run at about 53 megabytes per second vs. PCI's maximum of
   133, and high-speed USB microcontrollers are available now
   (although not from Microchip).

Um, 53MBps isn't even sampling on silicon yet, is it?  USB 1.0 certainly
can't do it.

Jeff:

High-speed USB 2.0 microcontrollers are ABSOLUTELY sampling on
silicon; I have a tube of Cypress's EZ-USB FX2 chips on my desk.
