Derivation of a calculated temperature comes from application of the calculated power to a reference thermal solution model. Reducing the influence of actual die temperature on the boost algorithm is an intentional tradeoff to increase deterministic performance of the device. AMD Embedded Solutions Guide by RTC Media - Issuu The calculated temperature is then combined with temperature data from other thermal entities to determine if thermal headroom exists. Other thermal entities can act as heat sources or sinks, depending on[…]
