From: David Sher  <sher>

I need some help from some of you Motorolla types out there.
I'm working on a paper that compares the speed of a parallel machine at BBN
called the butterfly whose base processor is the 68000 with the
speed of a parallel processor at CMU called the WARP with a custom built
processor for certain computer vision tasks.  I need to determine
the speed of the Butterfly if  the 68000's were replaced by 68020's with
floating point coprocessors, 68881's or in fact anyone else's coprocessors.
So much for motivation.  The information I need is the timings for
32 bit word integer add subtract and multiply and memory to register transfer
64 bit word floating point add subtract and multiply and memeory to register
transfer.
Thanks in advance!
