Techniques for performing progressive boot to reduce perceived boot time for a wireless device are described. Program codes to be stored in a bulk non-volatile memory may be partitioned into multiple code images. A first code image may include program codes used to support basic functionality of the wireless device. A second code image may include the remaining program codes. For progressive boot, the first code image may be loaded first from the bulk non-volatile memory. Once the first code image has been loaded, the wireless device may be rendered operational and may appear as functional to a user. While the wireless device is operational, the second code image may be loaded from the bulk non-volatile memory as background task and/or on-demand as needed.

Progressive boot for a wireless device

In general, the disclosure is directed to techniques for reducing power consumption within computing devices, such as wireless communication devices. A device dynamically adjusts the CPU clock frequency based on CPU load in order to reduce power consumption. The device monitors the load of the CPU using a number of sample interrupts. The device determines whether to adjust the clock frequency based on the monitored load of the CPU. In general, the device increases the clock frequency when the load of the CPU is high and decreases the clock frequency when the load of the CPU is low.
