Abstract: Aspects of the disclosure are directed to reduction of data transfer overhead. In accordance with one aspect, increment a function call counter for an executed function call; decrement the function call counter for an executed return from function call; infer the indirect branch address based on a function call counter value and when a cumulative count of received executed atoms indicates a return from function call has been executed; oversaturate the function call counter at a maximum counter value if the function call counter contains the maximum counter value and a subsequent function call is executed; and undersaturate the function call counter at a minimum counter value if the function call counter contains the minimum counter value and a subsequent return from function call is executed.

Abstract: Methods and apparatuses to power up multiple load circuits are presented. The apparatus includes a power delivery network, multiple load circuits configured to be powered via the power delivery network, and a wakeup control circuit configured to power up the multiple load circuits at a frequency based on a resonance frequency of the power delivery network. The method includes delivering power to the multiple load circuits by a power source via a power delivery network and powering up the multiple load circuits at a frequency, by a wakeup control circuit, based on a resonance frequency of the power delivery network.
