Summary: There's a Data Flow Processor available.



If you want a "canned" array processor, this is not for you.  But,
if you want a powerful fixed point processor that you can program
yourself, read on.

It's a bit unconventional, but there's a very powerful board
available from:

Data Flow Imaging, Inc.
42 Charles St.
Suite 2-C
Westwood, N.J. 07675
(201) 666-7970

This board plugs into a PC, XT, or AT.  It uses four uPD7281 Data
Flow Processors.  If you can use 17 bit (16 bit magnitude plus sign)
fixed point math, and you can pipeline your algorithms, you should
take a look.  You can use floating point routines, but the hardware is
fixed point.   This thing will do a 16 X 16 matrix times another 16 X 16
matrix in about 3.8 milliseconds (17 bit fixed point numbers) -- not bad
for under $1,000.

The Data Flow Architecture is real neat!
