Reservation station including addressable constant store for a floating point processing unit

摘要: A reservation station with an addressable constant store enables the provision of floating point constants to arithmetic units in a unit superscalar processor. Floating identifiers supplied instructions index into and addressed are provided internal, extended-precision format which provides extra precision and/or range when compared formats available external unit. In this way, full can be for use microcoded instruction sequences. Additionally, internal may rounded accordance prevailing rounding mode provide values implementing load instructions.
