P1754

    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.
