Abstract
A design structure for a processor may be embodied in a machine readable medium for designing, manufacturing or testing a processor integrated circuit. The design structure may control heat generation in a multi-core processor. The design structure may specify that each processor core includes a temperature sensor that reports temperature information to a processor controller. The design structure may also specify that if a particular processor core exceeds a predetermined temperature, the processor controller disables that processor core to allow that processor core to cool. The design structure may also specify that the processor controller enables the previously disabled processor core when the previously disabled processor core cools sufficiently to a normal operating temperature. In this manner, a multi-core processor may avoid undesirable hot spots that impact processor life.
