Abstract
Methods and apparatus to provide per die temperature programming for thermally efficient integrated circuit (IC) operation are described. In some embodiments, the junction temperature of an IC component is determined, e.g., to reduce power consumption and/or improve performance. Other embodiments are also described.
Claims19
An apparatus comprising:
- a storage device to store one or more bits that cause a logic to operate at a frequency level corresponding to a junction temperature of the logic;
- and
- a frequency controller to generate a clock signal corresponding to the frequency level,
- wherein a thermal design power of the logic is to be determined based on a value of a power leakage and a dynamic capacitance of the logic.
1 more element
A method comprising:
- determining a junction temperature of a logic;
- storing one or more data bits corresponding to one or more frequency levels in a storage device;
- generating a clock signal in accordance with at least one of the frequency levels that causes the logic to operate at a temperature that is equal to or less than the junction temperature;
- and
- determining at least one of:
- a thermal design power (TDP) of the logic based on stored values corresponding to power leakage and dynamic capacitance of the logic or a value of dynamic capacitance of the logic during operation of the logic.
3 more elements
A system comprising:
- a display device to display one or more images;
- a non-volatile memory to store one or more bits corresponding to one or more frequency levels;
- a programmable frequency controller coupled to the display device and configured to generate a clock signal in accordance with at least one of the frequency levels to cause a logic to operate at a temperature that is equal to or less than a junction temperature of the logic;
- and
- a plurality of processor cores to generate data corresponding to the one or more images.
2 more elements
A computer-readable medium comprising one or more instructions that when executed on a processor configure the processor to:
- determine a junction temperature of a logic;
- store one or more data bits that cause the logic to operate at a frequency level corresponding to the junction temperature of the logic;
- and
- determine the thermal design power of the logic based on a value of a power leakage and a dynamic capacitance of the logic.
