[comp.sys.ibm.pc.misc] Weitek instructions

marshall@wind55.seri.gov (Marshall L. Buhl) (11/29/90)

I'm in the process of ordering a Dell 483/33 tower machine to use as a
Unix server.  We're going to be running FORTRAN code on it and will have
a Weitek 4167 chip in it.  I've ordered the Greenhill FORTRAN compiler
from Oasys and I understand it only supports 1167 code.

I don't know the difference between the two.  I've never used a Weitek
before.  Is the 1167 a subset of the 4167?  Will a 4167 running 1167
code be faster than the 486?  By how much?  We use a mix of floating
point (usually single precision) and trig functions.

Any input would be greatly appreciated.
