The MC68882 floating-point coprocessor (FPCP) fully implements the IEEE Standard for Binary
Floating-Point Arithmetic (ANSI-IEEE Std 754-1985) for use with the NXP® M68000 Family
of microprocessors. The MC68882 provides an increased level of performance in a coprocessor
that is fully compatible and physically interchangeable with the MC68881.
Intended primarily for use as a coprocessor to the MC68020/MC68030 32-bit microprocessor,
the MC68882 provides a logical extension to the main processing unit integer data processing
capabilities. This coprocessor provides a very high performance floating-point arithmetic unit
and a set of floating-point data registers utilized in a manner that is analogous to the use of the
integer data registers. The MC68882 instruction set, a natural extension of all earlier members
of the M68000 Family, supports all of the addressing modes of the host MPU.
