Abstract:
Methods and apparatus are provided for sharing storage and execution resources between architectural units in a microprocessor using a polymorphic function unit. A method for executing instructions in a processor having a polymorphic execution unit includes the steps of reloading a state associated with a first instruction class and reconfiguring the polymorphic execution unit to operate in accordance with the first instruction class, when an instruction of the first instruction class is encountered and the polymorphic execution unit is configured to operate in accordance with a second instruction class. The method also includes the steps of reloading a state associated with a second instruction class and reconfiguring the polymorphic execution unit to operate in accordance with the second instruction class, when an instruction of the second instruction class is encountered and the polymorphic execution unit is configured to operate in accordance with the first instruction class.
