Floating point scaling processors, methods, systems, and instructions

An apparatus comprising:

• a plurality of registers;
• and
• a floating point execution unit coupled with the plurality of registers, the floating point execution unit operable, in response to a floating point scaling instruction indicating a first source including one or more floating point data elements that are not required to have integer values, indicating a second source including one or more corresponding floating point data elements, and indicating a destination, to store a result in the destination, the result including one or more corresponding result floating point data elements, each of the one or more result floating point data elements including a corresponding floating point data element of the second source multiplied by a base raised to a power of an integer representative of the corresponding floating point data element of the first source.

An article of manufacture comprising:

• a machine-readable storage medium including one or more solid data storage materials, the machine-readable storage medium storing a floating point scaling instruction,
• the floating point scaling instruction to indicate a first source including one or more floating point data elements that are not required to have integer values, to indicate a second source including one or more corresponding floating point data elements, and to indicate a destination storage location, and the floating point scaling instruction if executed by a machine operable to cause the machine to perform operations comprising:
• storing a result in the destination storage location, the result including one or more corresponding result floating point data elements, each of the one or more result floating point data elements including a corresponding floating point data element of the second source multiplied by a base raised to a power of an integer representative of the corresponding floating point data element of the first source.
