80-BIT CHMOS III NUMERIC PROCESSOR EXTENSION

The Intel M80C287 is a high-performance numerics processor extension that extends the architecture of the M80C286 CPU with floating point, extended integer, and BCD data types. A computing system that includes the M80C287 fully conforms to the IEEE Floating Point Standard. Using a numerics oriented architecture, the M80C287 adds over seventy mnemonics to the instruction set of the M80C286 CPU, making a complete solution for high-performance numerics processing. The M80C287 is implemented with 1.5 micron, high-speed CHMOS III technology and packaged in a 40-pin CERDIP. The M80C287 is upward object-code compatible from the M80287 and M8087 numerics coprocessors. With proper socket design, either an M80287 or an M80C287 can use the same socket.

■ High Performance 80-Bit Internal Architecture
■ Implements ANSI/IEEE Standard 754-1985 for Binary Floating-Point Arithmetic
■ Implements Extended M387 Numerics Coprocessor Instruction Set
■ Two to Three Times M8087/M80287 Performance at Equivalent Clock Speed
■ Low Power Consumption
■ Upward Object-Code Compatible from M8087 and M80287
■ Interfaces with M80286 and M80C286 CPUs
■ Expands CPU’s Data Types to Include 32-, 64-, 80-Bit Floating Point, 32-, 64- Bit Integers and 18-Digit BCD Operands
■ Directly Extends CPU’s Instruction Set to Trigonometric, Logarithmic, Exponential, and Arithmetic Instructions for All Data Types
■ Full-Range Transcendental Operations for SINE, COSINE, TANGENT. ARCTANGENT and LOGARITHM
■ Built-In Exception Handling
■ Operates in Both Real and Protected Mode Systems
■ Eight 80-Bit Numeric Registers, Usable as Individually Addressable General Registers or as a Register Stack
■ Available in 40-pin CERDIP (See Packaging Outlines and Dimensions, order Ý231369)
■ Military Temperature Range: -55°C to +125°C (TC)
