Floating point scaling processors, methods, systems, and instructions

摘要

A method of an aspect includes receiving a floating point scaling instruction. The floating point scaling instruction indicates a first source including one or more floating point data elements, a second source including one or more corresponding floating point data elements, and a destination. A result is stored in the destination in response to the floating point scaling instruction. The result includes one or more corresponding result floating point data elements each including a corresponding floating point data element of the second source multiplied by a base of the one or more floating point data elements of the first source raised to a power of an integer representative of the corresponding floating point data element of the first source. Other methods, apparatus, systems, and instructions are disclosed.

1. A method comprising:
receiving a floating point scaling instruction, the 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; and storing a result in the destination in response to the floating point scaling instruction, the result including one or more result floating point data elements having a same floating point format as the one or more floating point data elements of the second source, 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.
