VECTOR EXECUTION UNIT WITH PRENORMALIZATION OF DENORMAL VALUES

摘要

A method, circuit arrangement, and program product for executing instructions including denormal values for one or more operands in a vector execution unit. A denormal value operand may be prenormalized by a first processing lane of the vector execution unit upon detecting the denormal value. The prenormalized value and any other operands of the instruction may be communicated to a dot product adder of the vector execution unit. The dot product adder performs at least a portion of the floating point operation with the prenormalized value and any other operands of the instruction.

1. A method for executing floating point instructions in a vector execution unit, wherein execution of the floating point instruction performs a floating point operation on at least one operand identified by the instruction, wherein the operand is a denormal value, the method comprising:
prenormalizing the denormal value in a first processing lane of the vector execution unit to generate a prenormalized value; and performing at least a portion of the floating point operation using the prenormalized value in a dot product adder of the vector execution unit.
