25 because of the OPP density, we can only choose an OPP with a power

38 injection period, we can mitigate the temperature by modulating the
47 At a specific OPP, we can assume that injecting idle cycle on all CPUs
49 idle state target residency, we lead to dropping the static and the
69 We use a fixed duration of idle injection that gives an acceptable
132 - It is less than or equal to the latency we tolerate when the
134 user experience, reactivity vs performance trade off we want. This
137 - It is greater than the idle state’s target residency we want to go
138 for thermal mitigation, otherwise we end up consuming more energy.
143 When we reach the thermal trip point, we have to sustain a specified
144 power for a specific temperature but at this time we consume::
151 because we don’t want to change the OPP. We can group the
153 ‘Dynamic Power Coefficient (Cdyn)’ Simplifying the above, we have::
159 tree. So with the idle injection mechanism, we want an average power
171 At this point if we know the running period for the CPU, that gives us
172 the idle injection we need. Alternatively if we have the idle
173 injection duration, we can compute the running duration with::
177 Practically, if the running power is less than the targeted power, we
182 However, in this demonstration we ignore three aspects:
