It mentioned the "extended processor unit interface"
to Z8000 cpu with a 6 page chapter. some reversed
instructions can be used as EPU instructions. It said
an EPU can be a floating point processor, a graphics
processor, a network processor.... It described the
EPU hardware interface but didn't say more about a
floating point processor. If you have interest I can
mail you a copy.

I copied the Z8038 part from the book "The Z8000
microprocessor, A design handbook" by Bradly, K.
Fawcett. I remember that somebody on the list tried
to
make a collection of zilog chip documents. I'd
like
to
mail the 20 pages to him. Please send me email if
it
is you. Thanks.
Hi Shaun
Does your book describe the floating point
processor
( that was never released ). I was wondering because
the CP/M-8000 that I've been playing with ( accually
the C compiler ) uses the floating point processors
instructions and then exception traps them to
execute
the floating point code. The format for using these
traps would be the same as was expected for the
real FPU.
