Techniques and apparatuses are described that use transaction queue lengths to alter a clock frequency that controls access to a memory of an electronic device. Techniques include detecting that a transaction queue threshold has been violated, initiating a counter to measure a time duration, determining that the transaction queue threshold continues to be violated for the time duration and, in response, altering the clock frequency that controls access to the memory of the electronic device.

Controlling memory frequency based on transaction queue occupancy

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.

This disclosure describes methods, devices, systems, and procedures in a computing system for capturing a configuration state of an operating system executing on a central processing unit (CPU), and offloading resource-related tasks, based on the configuration state, to a resource management unit such as a system-on-chip (SoC). The resource management unit identifies a status of each resource based on the captured configuration state of the operating system. The resource management unit then processes tasks associated with the status of the resources, such as modifying a clock rate of a clocked component in the computing system. This can alleviate the CPU from processing those tasks thereby improving overall computing system performance and dynamics.

According to an aspect, a system includes a battery configured to be charged by a power source, a charging circuit coupled to the battery, and a battery charging manager configured to communicate with the charging circuit to control a charging of the battery by the power source. The battery charging manager obtains a charge pattern including an end charge time corresponding to a time when the battery is estimated to be disconnected from the power source. The battery charging manager controls the charging circuit to charge, over a first charging period, the battery to a temporary charge level, maintain, over a relaxation period, a battery charge level between the temporary charge level and a maintenance charge level, and charge, over a second charging period after the relaxation period, the battery to a maximum battery charge level before the end charge time.

Predictive charging to reduce battery capacity degradation

A system and method for dynamically cancelling haptic feedback in certain areas of a touchpad, and/or to dynamically isolating haptic feedback in certain areas of the touchpad, may enhance flexibility, utility and functionality of the touchpad. A first haptic engine may generate and transmit haptic feedback in response to an input detected in an input area of the touchpad. A second haptic engine may generate haptic cancellation feedback, and transmit the cancellation feedback after a time delay, to cancel out the effect of the haptic feedback in a cancellation area of the touchpad. This may allow a user to experience the haptic feedback in response to an input in the input area, and to rest hand(s) on other portions of the touchpad display without feeling haptic feedback in the other portions of the touchpad.

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.

Secure persistent software updates

A computing device updates wireless connectivity information while the device is in an idle state, in expectation of user-interaction. Power is suspended to wireless network circuitry in a mobile device, for example, when the device is in an idle state. On detecting a movement of the mobile device, a location sensor is activated to read a current location of the mobile device while power to the wireless network circuitry is suspended. Based on the current location being a threshold distance from a location determined before power to the wireless network circuitry was suspended, the wireless network circuitry is activated and a current listing of wireless access points near the mobile device is determined without user interaction with the virtual features of the device.

In one general aspect, a computing device can include a base, and a lid coupled to the base. The lid can house a display section including a first side and a second side. The display section can include a display device having a first side and a second side. The first side of the display device can be located on the first side of the display section and the second side of the display device can be located on the second side of the display section. An enclosure can surround the display device. The enclosure can include a fluid, a plurality of particles suspended in the fluid, and a layer of circuitry disposed on a surface of the enclosure. The computing device can be configured to control movement of the particles within the fluid by applying an electric field to the layer of circuitry.

In one general aspect, a computing device can include a base, and a lid coupled to the base, the lid housing a display device that includes a first electrochromic material, a second electrochromic material, and an organic light emitting diode (OLED) display. The OLED display can be located between the first electrochromic material and the second electrochromic material.
