Motorola 68882

The Motorola 68882 math coprocessor is a floating-point unit (FPU) that was produced by Motorola's Semiconductor Products Sector for use with the Motorola 68020 or 68030 processor.Section 1: Generation Description by Motorola, MC68881/MC68882 Floating-Point Coprocessor User's Manual p.1-1. 1987.
==Features==
The 68882 succeeded the Motorola 68881 math coprocessor and featured improved pipelining. The 68881 and 68882 are actually interchangeable between the 68020 and 68030, with 10% performance improvement observed in the 68882.Frequently Asked Questions (FAQ) by Robert Boys, comp.sys.m68k. 1996-01-06.
