MC68882 : Math Coprocessor

●

Features

Documentation

Design Tools

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 Motorola 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.

MC68882 Features

●

8 general-purpose floating-point data registers, each supporting a full 80-bit extended precision real data format (a 64-bit

mantissa plus a sign bit, and a 15-bit signed exponent).

●

67-bit arithmetic unit to allow very fast calculations, with intermediate precision greater than the extended precision format.

67-bit barrel shifter for high-speed shifting operations (for normalizing, etc.).

46 instructions, including 35 arithmetic operations.

Full conformance to the ANSI-IEEE 754-1985 standard, including all requirements and suggestions.

Support of functions not defined by the IEEE standard, including a full set of trigonometric and transcendental functions.

7 data formats: byte, word, and long word integers; single, double, and extended precision real numbers; and packed binary

coded decimal string real numbers.

●

22 constants available in the on-chip ROM

Virtual memory/machine operations.

Efficient mechanisms for exception processing, context switches, and interrupt handling.

Fully concurrent instruction execution with the main processor.

Use with any host processor, on an 8-, 16-, or 32-bit data bus.

Concurrent execution of multiple floating-point instructions.

Special-purpose hardware for high-speed conversion of binary real memory operands to/from the internal extended format.

Simultaneous access to the floating-point registers by the MC68882's conversion and arithmetic processing units.

Reduced coprocessor interface overhead to increase throughput.
