An apparatus and method for maintaining a floating point data segment selector are described. In one embodiment, the method includes the detection of a micro-operation of a memory referencing macro-instruction from one or more micro-operations to be retired during a system clock cycle. When the detected micro-operation triggers an event, a micro-code event handler is triggered to initiate an update of a floating point data segment selector information associated with the detected micro-operation. Otherwise, FDS update device is triggered to update the floating point data segment selector information associated with the detected micro-operation. |
