We have built a plug board based on the motorola spec which
comprises a 68020 / 68881 and pals and plugs in place of
the 68000.
This board works fine except we are trying to test the
floating point unit.
I seem to remember that somone said it was possible to
force lattice 4.0 to use the 68881 fpu instead of software
emulation. Can anyone tell me how to do this ?
Help , I have tried using both the standard math library
and the FFP library but the test program still runs at a
speed you would expect for software emul.
Thanks in advance for any assistance,
