Re: Hardware for high performance

Hi Guys,

Thanks for the replies! Very helpful.

The only PCI card that is sending data into the computer over the PCI
bus is the Digitiser card. The other cards are only controlled during
set up to set things like pulse repetition rate, voltage, pulse width
etc. The cards are all hardware controlled so it hasn't been to much of
a problem to write the driver and get the software running. It's now a
matter of optimising and stretching it to it's limit.

The driver still has some functionality to implement and for the moment
i'm limited to grabbing one pulse at a time (1-d array of 1000pts) via
a call to the dll. I then write that to file using write to binary
file. I then make the next call. I've experimented just grabbing the
data with and without saving and there is not much of a noticable drop
in the capture rate (i'm making about 250 calls to the capture data dll
per second and about 2000 calls to another dll per second to extract
the data - 8 channels so about 250 captured waveforms per channel per
second).

Do you think i should send the data out of the loop before saving it?

Thanks.
