Abstract
A system and method for reducing heat in a portable computing device includes clocking a processor such that it is provided with a full frequency over time tto t. A timer is set to trigger a forced power collapse ('FPC') that removes all power to the processor from time tto time t. At time t, the processor may be awakened such that it can resume processing at the full frequency. Advantageously, during the FPC, no leakage power ('P') is consumed by the processor between tand t. The result is that the processor averages the same processing efficiency over time tto tas it otherwise would have if a reduced frequency had been provided to it. However, because no Pwas consumed during the FPC, the generation of heat between time tand tthat is related to Pis avoided.
