Table E-3 lists all the data formats and types supported by the MC68040 FPU. Also
included are the data formats and types that the MC68040 FPU does not support but that
are supported by the M68040FPSP.
The M68040FPSP provides system designers with a simple path to port existing
MC68881/MC68882 exceptions handlers to the MC68040. It also provides an entry point
for the IEEE-defined exception conditions listed in Table E-4.
The M68040FPSP is written in M68000 family assembly code and comes with an
installation guide. Tape contains both Motorola syntax and UNIX “as” syntax. Tape
cartridge (M68040FPSPT) media is available in CPIO and TAR formats. Also available is
9-track (M68040FPSPP) media in high or low density as well as CPIO and TAR formats. A
license is required to obtain rights to use and distribute the M68040FPSP. License terms
include the right to use and modify source code and redistribute resulting object code.
