P1754
<processor, standard> IEEE Std 1754-1994 "A 32-Bit Microprocessor Architecture".
The
IEEE standard defining a version of the
SPARC microprocessor architecture.
The P1754 standard (the first microprocessor standard) was approved after four years on 1994-03-17.
It is compatible with, but distinct from, SPARC International's 32 bit version of the SPARC Architecture, SPARC V8, from which it is largely derived.
It is possible for a processor to comply with neither, one, or both specifications.
