Are you sure that you even need a DSP? Can't you use a simple AD/DA
interface card and do all the calculations on the PC? Any recent PC
processor is magnitudes faster than the old TMS320 on this board.

I can't. I need 16-bit (true 16-bit) performance, four channels in, four
channels out, from DC up.

We don't have a PCI card. I worked on a few some years ago but never
brought anything to production.
If it lives outside the PC Box, we can probably help. Our boards have
either high speed or full speed USB ports and RS-232. We have boards with
built in EZ-Kit style debuggers.
We are in the process of defining a set of PC/104 family Sharc based DSP
cards. If you (or anyone) have ideas or an interest, let me know.

1. Analog Devices and Texas Instruments both make DSP chips with PCI
bus interfaces.
1.a. I know the TI chips have eval boards (made by Spectrum Digital)
that come with bare-bones drivers.
1.b. I strongly suspect that Analog Devices has the same thing
1.b.1. Danville Signal Processing -- http://www.danvillesignal.com/ --
is an Analog Devices Only shop, they may have something. And Al, if
not, why not?
1.c. Ditto Freescale.
2. Consider your friendly local sound card. If you can get by with two
channels of AC-coupled data with 16-bit ADCs then your solution may
already be built into your motherboard.

Hello,
For a laoboratory measurement control / data acquisition system I'd like
to use a DSP board that plugs into a standard PC. A nice, low-cost card
that fits the bill is this one:
http://www.signalogic.com/index.pl?page=pc32
However, it only comes with an ISA slot. All PCI cards that I could find
are much more expensive and have tons of additional performance that I
don't need.
Does anybody know of a simpler, cheaper model with PCI? I've actually
seen stuff for "Compact PCI" or "PC104" buses -- but to use those I'd
probably have to build te entire PC on this bus system which would cost
more than a high-performance DSP board in a consumer PC.
The board must be supported by Linux drivers. The actual DSP hardware on
the board is of no importance because I'm starting from zero anyway, as
long as the development tools are not prohibitively expensive for a
University project.
Thanks for any suggestions,
robert
