MC68060 Software Package
The floating-point emulation package provides the following services:
Table C-2 lists a brief comparison among the M68000 family floating-point processors.
The unimplemented floating-point instructions, effective addresses, and data types that are
handled by the M68060SP are outlined in Table C-3 and Table C-4.
C-12
1. Floating-point unimplemented instruction exception handler
2. Floating-point unimplemented data-type exception handler
3. Floating-point unimplemented effective address handler
4. Floating-point arithmetic exception handlers
5. Floating-point library
Is the default result stored in the destination register for exception-enabled register-to-
register or memory-to-register operations?
Is the default result stored for exception-enabled FMOVE OUT?
+ Undefined result written by processor
* Floating-point software package assistance needed to store the default result
