I've been looking for PC/104 DSP options and am wondering if anyone has recommendations. I have a portable, stand alone data acquisition product that currently uses a custom system board and would like to replace it with a PC/104 system running linux. The system records pressure pulses (~ 1 pulse / second) in an noisy environment (pump noise, etc.). I am interested in adding a DSP card for filtering and freeing up the processor for user interface, networking, database, etc.
I've looked at cards from: Bittware, RTD Embedded, S&K Electronics, Signallogic, Arius, Mango DSP, Sheldon, SystemExcelerator and Sundance. Obviously, some of these are focused on communications or imaging and some blow the budget, although the RTD products are < $1K. I've also seen some non-PC/104 products that might work: dspstak from Danville Signal Processing or DSP Stamp from Cambridge Signal Processing. I haven't checked out PCI DSP cards - possibly they're more affordable and could be plugged into a PC/104plus system?
Anyone have any recommendations, pointers or war stories?
Thanks, Bill Turner
