摘要:
A system and method to optimize multi-core microprocessor performance using voltage offsets is presented. A multi-core device tests each of its processor cores in order to identify each processor core's optimum supply voltage. In turn, the device configures voltage offset networks for each processor core based upon each processor core's identified optimum supply voltage. As a result, the offset voltages produced by the voltage offset networks are subtracted from the multi-core device's main voltage, which results in the voltage offset networks supplying optimum supply voltages to each processor core. The voltage offset networks may include fuses to generate a fixed voltage offset, or the voltage offset networks may include a control circuit to dynamically adjust voltage offsets during the multi-core device's operation.

The disclosed methodology and apparatus may reduce heat generation in a multi-core processor. In one embodiment, a multi-core processor cycles selected processor cores off in a predetermined pattern across the processor die over time to reduce the average heat generation by the processor. The disclosed multi-core processor may reduce or avoid undesirable hot spots that impact processor life.

摘要:
The disclosed methodology and apparatus may control heat generation in a multi-core processor. In one embodiment, each processor core includes a temperature sensor that reports temperature information to a processor controller. If a particular processor core exceeds a predetermined temperature, the processor core disables that processor core to allow it to cool. The processor core enables the previously disabled processor when the previously disabled processor core cools sufficiently to a normal operating temperature. The disclosed multi-core processor may avoid undesirable hot spots that impact processor life.

摘要:
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.

摘要:
A processor has multiple cores with each core having an associated function to support processor operations. The functions performed by the cores are selectively altered to improve processor operations by balancing the resources applied for each function. For example, each core comprises a field programmable array that is selectively and dynamically programmed to perform a function, such as a floating point function or a fixed point function, based on the number of operations that use each function. As another example, a processor is built with a greater number of cores than can be simultaneously powered, each core associated with a function, so that cores having functions with lower utilization are selectively powered down.
摘要:
A method for optimizing execution of a single threaded program on a multi-core processor. The method includes dividing the single threaded program into a plurality of discretely executable components while compiling the single threaded program; identifying at least some of the plurality of discretely executable components for execution by an idle core within the multi-core processor; and enabling execution of the at least one of the plurality of discretely executable components on the idle core.
