Our center has a project to produce a small meteorological radar 
which observes the Doppler shift due to winds.
It requires fast data transfer between A/D converter in the receiver 
and a computer.
I think we need a data transfer rate of around 1 MBytes/sec.
In the computer, we need to calculate power spectra of the data by FFT.

Does anybody know good parallel interface and DSP (Digital Signal Processor) 
(or Floating Point Accelerator) for HP9000/300 or other workstations?

I am wondering if I can use fast HP-IB or SCSI bus for the data tranfer.
Is it difficult to use such bus like SCSI for data transfer?
How fast are these buses with HP9000/300 series?

Thank you in advance.
