If you are doing lots of FFT's and other image processing operations,
you may be interested in looking at some of the third party add on
external boxes for Sun workstations.  There are several which have
been around for a while.

For on-board graphics solutions, Sun recently introduced two new
graphics accelerators when they introduced the SPARCstation 2.  They
are the GS and the GT option.  They also introduced the VX/MVX
graphics subsystem at SIGGRAPH '90.  The quickie explanation of these
products follows:

GS: 24bit framebuffer, 16bit Zbuffer, this card uses all 3 S bus slots
on a SS2. It provides some 2D and 3D graphics acceleration.

GT: 24bit (double)framebuffer, 24bit Zbuffer, this card resides in an
external chasis.  It provides impressive 3D graphics acceleration.

VX/MVX: Sun's i860 graphics subsystem! You need a SPARCstation 330 for
this option (requires VME slots).  The VX/MVX combo provides you with
a *hot* framebuffer card (VX) and a 4 PE i860 accelerator card(MVX) for your
*cpu hogging* graphics applications.

For more information, reuest the appropriate `Technical White Papers'
from you local Sun rep.  If you wish to chit-chat about these
accelerators, send me personal mail to the address shown below.

I have no affiliation with Sun Microsystems. I am a Sun (& SGI) user.
