    • A floating point processor unit executes a floating point compare instruction with two operands of the same or different precision by comparing the two operands in integer format, which speeds up the execution of the floating point compare instruction significantly. The floating point processor now executes the floating point compare instruction at least twice as fast or faster (e.g., two clock cycles instead of five clock cycles in the prior art) for nearly most operand cases (e.g., 99% of all cases). Only the rare corner cases require additional operations on one of the operands and thus require additional cycles of execution time because the integer compare operation will not work for these corner cases. This is due to the fact that one operand is a single precision subnormal number in an unnormalized representation (i.e., has two representations) and the other operand is in the SP subnormal range such that the integer compare operation will fail.
    • 浮点处理器单元通过比较整数格式的两个操作数来执行具有相同或不同精度的两个操作数的浮点比较指令,这显着地加快了浮点比较指令的执行。 浮点处理器现在对于几乎大多数操作数情况(例如,所有情况的99%),至少执行两倍快或更快(例如,现有技术中的两个时钟周期而不是五个时钟周期)的浮点比较指令。 只有罕见的角落情况需要在其中一个操作数上进行额外的操作,因此需要额外的执行周期,因为整数比较操作将不适用于这些角色。 这是由于一个操作数是非正规化表示中的单精度子正规数(即,具有两个表示),另一个操作数处于SP子正常范围,使得整数比较操作将失败。
