Abstract
A method and instruction for converting a number from a floating point format to an integer format are described. Numbers are stored in the floating point format in a register of a first set of architectural registers in a packed format. At least one of the numbers in the floating point format is converted to at least one 8-bit number in the integer format. The 8-bit number in the integer format is placed in a register of a second set of architectural registers in the packed format.
Claims26
An apparatus, comprising:
- a first storage area to store packed data, the first storage area representing a register in a first set of architectural registers;
- a second storage area to store packed data, the second storage area representing a register in a second set of architectural registers;
- and
- logic to convert a first plurality of numbers in a floating-point format that are stored in the first storage area to a second plurality of numbers in an integer format, wherein each of the second plurality of numbers comprises 8-bits, and to store the second plurality of numbers in the second storage area.
An apparatus, comprising:
- a first storage area to store packed data, the first storage area representing a register in a first set of architectural registers;
- a second storage area to store packed data, the second storage area representing a register in a second set of architectural registers;
- and
- logic to convert a first plurality of numbers in a floating-point format that are stored in the first storage area to a second plurality of numbers in an integer format, wherein the second plurality of numbers each comprises 16-bits, and to store the second plurality of numbers in the second storage area.
