摘要
A method and apparatus generates control information that indicates whether to change a counter value associated with a particular load instruction. In response to the control information, the method and apparatus causes a hysteresis effect for operating between a speculative mode and a non-speculative mode based on the counter value. The hysteresis effect is in favor of the non-speculative mode. The method and apparatus causes the hysteresis effect by incrementing the counter value associated with the particular load instruction by a first value or decrementing the counter value by a second value. The first value is greater than the second value.
