This document describes systems and techniques for adaptive frequency control in integrated circuits. In response to operating conditions that permit a lower frequency of a clock signal, the described systems and techniques dynamically reduce the clock frequency without adjusting the frequency of an input clock signal. The clock frequency is decreased by gating a fraction of the input clock signal and stretching the ungated cycles by an offset amount. By dynamically adjusting the clock frequency in this manner, an integrated circuit can change its clock frequency more quickly and maintain the supply voltage closer to a lower voltage limit to reduce power consumption and allow safer operations.

Adaptive frequency control in integrated circuits

Techniques and devices for secure persistent software updates are described. Through use of these techniques and devices, events that can prevent a software update from occurring can be detected and operations that enable the software update to occur can be performed. The techniques are capable of ensuring a computing device is using a latest software and that persistent software updates continue, despite any efforts to compromise the computing device.
