Abstract

A processor for performing floating point arithmetic operations is provided that includes a circuit that performs a first floating point arithmetic operation on a set of operands in a first cycle and a second floating point arithmetic operation on an operand and a result of the first floating point arithmetic operation during a second cycle. A control circuit is provided for, in a third cycle, transferring a result of the second floating operation to the first floating point circuit for a first floating point operation in a next successive cycle while rounding the result of the second floating point operation.
