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.
