General Description
The NS32081 Floating-Point Unit functions as a slave processor
in National Semiconductor’s Series 32000É microprocessor
family. It provides a high-speed floating-point instruction
set for any Series 32000 family CPU, while remaining
architecturally consistent with the full two-address architecture
and powerful addressing modes of the Series 32000
micro-processor family.
