Method and Device for Switching Over in a Computer System Having at Least Two Execution Units

A method for switching over in a computer system having at least two execution units, the method comprising:

• switching between at least two operating modes, the operating modes corresponding to states of the computer system, a first state corresponding to a comparison mode and a second state corresponding to a performance mode, wherein an event may occur by which the computer system attains an otherwise undefined state;
• and
• assuming, in response to the occurrence of any such event, the second state which corresponds to the performance mode.

A device for switching over in a computer system having at least two execution units, comprising:

• a switching arrangement to switch between at least two operating modes, the operating modes corresponding to states of the computer system, a first state corresponding to a comparison mode and a second state corresponding to a performance mode, wherein an event may occur by which the computer system attains an otherwise undefined state;
• and
• an assuming arrangement to assume, in response to the occurrence of any such event, the second state which corresponds to the performance mode.

A finite state machine for switching over in a computer system having at least two execution units, comprising:

• a switching arrangement to switch between at least two operating modes, the operating modes corresponding to states of the computer system, a first state corresponding to a comparison mode and a second state corresponding to a performance mode, wherein an event may occur by which the computer system attains an otherwise undefined state;
• and
• an assuming arrangement to assume, in response to the occurrence of any such event, the second state which corresponds to the performance mode.
