    摘要： Methods and apparatus relating to instructions with floating point control override are described. In an embodiment, floating point operation settings indicated by a floating point control register may be overridden on a per instruction basis. In an embodiment, at least one of the one or more floating point operation settings is to cause a modification to one of the one or more default settings during execution of the instruction, wherein the second logic is to perform the floating point operation, at least in part, based on the modified default setting. Other embodiments are also described.

    摘要： Embodiments of the present invention provide a method, apparatus and system of dividing a first number by a second number. Some demonstrative embodiments include generating a first value relating to the first number; generating a second value corresponding to a remainder of a division of the number one by the second number; and dividing the first value by the second value. Some demonstrative embodiments include generating a plurality of independent interim values by adding at least first and second sets of one or more carry bits of an encoded remainder value corresponding to a cycle of a division operation to at least first and second sets of one or more sum bits of the encoded remainder value, respectively; and generating a plurality of coefficients corresponding to a quotient digit of the cycle based on the plurality of interim values. Other embodiments are described and claimed.
