The Intel M80287 is a high performance numerics processor extension that extends the M80286/10 architec-
ture with floating point, extended integer and BCD data types. The M80286/20 computing system (M80286
and M80287) fully conforms to the proposed IEEE Floating Point Standard. Using a numerics oriented archi-
tecture, the M80287 adds over fifty mnemonics to the M80286/20 instruction set, making the M80286/20 a
complete solution for high performance numeric processing. The M80287 is implemented in N-channel, deple-
tion load, silicon gate technology (HMOS) and packaged in a 40-pin ceramic package. The M80286/20 is
object code compatible with the M80286/20 and M8088/20. Intel’s HMOS III process provides superior
radiation tolerance for applications with stringent radiation requirements.
