Would anyone know where I could find an FFT coprocessor board (Fast Fourier Transform) (HP or third party) for an HP9000 series 300 ? Thanks ! - John

For an FFT processor for the HP9000 s 300 try: Ariel Corporation 433 River Road Hughland Park, NJ 08904 Tele: 201-249-2900 FAX 201-249-2123 Telex: 499 7279 ARIEL I think the board runs under the HP BASIC and PASCAL operating system, but may also run under HP-UX. Check. Its been some time since I used their board. When I used it under HP BASIC ~5 years ago it computed a 1D complex 1024-pt FFT (16 bit integer) in about 10 milliseconds. Good luck. fmonaldo@aplcomm,jhuapl.edu Frank Monaldo

Add claims: uses Moto DSP56001 chip 10.25 MIPS std, faster available 1024 pt FFT in 3.39 msec 144 dB dynamic range Why not post whatever you find out?

I have an old version that I think is rated at about 1.0 msec for a 1024 pt. complex FFT (someone swiped all my spec sheets, but I think that's right). The catch is that you need a VME bus expander in addition to the card. Current pricing for the card is ~6K, I don't know how much our VME expander costs in real money, but HP sells it. There are some nice subroutine libraries available, too, though the more extravagant stuff will cost you. I was very pleased with the old card, and their new one should be an improvement.
