Greetings:
I have a radio that produces 14 bits at 56MS/s. The radio has no flow
control and I have to read samples into the PC's memory on one thread, and
write on a different one to disk.
Given today's PCs, 20GMIPS+, two 14 bit multiplications, and two NCOs
would not seem to be a problem. In addition, I would like to phase and
amplitude correct, which I presume would be a lot less intense than the
real to iq operation above.
Is there a repository of open source for these types of computation?
Thank you,
Alex
Don't let those GMIPS numbers fool you, they apply to data that is
already sitting in fast memory. Forget the processing, the hard part
of your problem is IO. How is the data acquired? GIGE? PCI? What is
your disk configuration? What O/S?
