System designers integrate the M68040FPSP into the system so that the user object code
runs unchanged and remains totally transparent to the end user. The M68040FPSP can
be installed into any operating system. It provides kernel routines to support
unimplemented instructions and unsupported data types. Unimplemented instructions for
end-user applications compiled for the MC68881/MC68882 are contained in a library for
improved performance. For all MC68040 floating-point instructions, the coprocessor ID
field must be 001. Table E-1 lists the floating-point functions implemented as instructions
by the MC68040.
