  • Floating point unit for calculating a compound instruction A+B.times.C in two cycles
    Patent number: 5530663
    Abstract: A floating point arithmetic unit that executes a single compound instruction that produces the result A+B.times.C with A, B and C being floating point numbers. Arithmetic on the exponents of A, B and C provide a normalized result of the multiplication before the addition takes place producing a normalized result of the compound instruction. The final normalized result is identical to a result that would be obtained by executing a separate instruction for the multiply, with normalized result, followed by an add instruction with a normalized result.
