Abstract:
This paper deals with the modelling of a CPU-GPUchip embedded in an Android phone. The model is used for
the estimation of variables that characterise the operating state of System on Chip (SoC). The proposed model
is built to demonstrate the causal relationships between the variables, through its interconnected structure of
subsystems. This structure allows the extension of other components or the easy exchange of subsystems in
the case of a change in components or operating mode. The model developed here requires no additional
instrumentation—other than the one present on the phone—which facilitates its implementation. It is used for
the estimation of the state of the system and can also be used for monitoring and behaviour prediction. The
model is validated and the results are promising for further implementation.
