Notably, in many PCDs, thermal energy levels measured by individual temperature sensors in the PCD may be attributable to a plurality of processing components, i.e. thermal aggressors. Generally, as more power is consumed by the thermal aggressors, the resulting generation of thermal energy may cause the temperature thresholds associated with temperature sensors located around the chip to be exceeded, thereby necessitating that the performance of the PCD be sacrificed in an effort to reduce thermal energy generation.

  • Publication number: 20150142203
    Abstract: A high accuracy on-chip thermal sensor includes an integrated circuit and sensing elements. The thermal sensor finds application in various mobile and battery powered devices and includes a processor that analyzes a measured temperature signal and decides if the thermal sensor operates in low or high power operational mode, or if the device's CPU is to be reset. A method utilizing the thermal sensor includes making comparisons to two threshold temperatures and operating at low power mode below the first threshold temperature, high power mode between the two threshold temperatures and causing reset if the second threshold temperature is exceeded. Low power operational mode includes a lower clock frequency, lower bias current and lower power consumption. Higher power operational mode is used when the upper threshold temperature is being approached and includes a higher data sampling frequency and more accurate temperature control and uses higher power.

  • Patent number: 9020655
    Abstract: A method and system for thermal management in integrated circuits and integrated circuit boards is described. In an embodiment, the circuit device board includes circuit devices, temperature sensors, and a thermal management unit. The thermal management unit receives thermal data from the temperature sensors and determines thermal reference points that define thermal regions. The thermal reference points are correlated with the operating characteristics of the circuit devices. When warranted, the thermal management unit makes independent corrective responses to each of the thermal regions. These corrective responses include modifying operating parameters, adjusting workload, and suspending operation of circuit devices within the thermal region. Thus, the disclosed method and system can preserve function in one thermal region while alleviating stress on another thermal region.
