Abstract
A temperature estimation circuit for estimating a temperature of an integrated circuit die comprises a temperature increase estimation circuit, having inputs operable to receive notification signals, each corresponding to a command signal passed to an integrated circuit, and an output providing a sum of temperature increase values, each corresponding to a temperature increase of the integrated circuit due to one of the command signals. The circuit further comprises a temperature decrease estimation circuit, having an input operable to receive a calculated die temperature value, and an output providing a temperature decrease value depending on a mathematical model of temperature decrease when no command signal is applied. The circuit further comprises a temperature calculation circuit, having a first input connected to the output of the temperature increase estimation circuit, a second input connected to the output of the temperature decrease estimation circuit, and an output providing the calculated die temperature value.
