    Abstract: Aspects of the present disclosure relate to protecting the contents of memory in an electronic device, and in particular to systems and methods for transferring data between memories of an electronic device in the presence of strong magnetic fields. In one embodiment, a method of protecting data in a memory in an electronic device includes storing data in a first memory in the electronic device; determining, via a magnetic sensor, a strength of an ambient magnetic field; comparing the strength of the ambient magnetic field to a threshold; transferring the data in the first memory to a second memory in the electronic device upon determining that the strength of the ambient magnetic field exceeds the threshold; and transferring the data from the second memory to the first memory upon determining that the strength of the ambient magnetic field no longer exceeds the threshold.

    Abstract: The disclosure generally relates to a memory power reduction scheme that can flexibly transition memory blocks among different power states to reduce power consumption (especially with respect to leakage power) in a manner that balances tradeoffs between reduced power consumption and performance impacts. For example, according to various aspects, individual memory blocks may be associated with an access-dependent age, whereby memory blocks that are not accessed may be periodically aged. As such, in response to the age associated with a memory block crossing an appropriate threshold, the memory block may be transitioned to a power state that generally consumes less leakage power and has a larger performance penalty. Furthermore, one or more performance-related criteria may be defined with certain memory blocks to prevent and/or automatically trigger a transition to another power state.

    Abstract: A hardware based motor controller may be used to generate chopped signals. The hardware based motor controller may decrease CPU bandwidth needed to perform functions related to motor control. In an aspect of the disclosure, a method and an apparatus are provided. The apparatus may be a motor controller for controlling a brushless motor. The motor controller may include a first carrier generator component for providing a first carrier. The motor controller may also include a first pulse generator component for providing a first pulse at a duty cycle. The first pulse generator component may be coupled to the first carrier generator component. Additionally, the first pulse generator may be configured to combine the first pulse with the first carrier to generate a first output pulse. Additionally, the first pulse generator may also be configured to output the first output pulse to drive a first leg of the brushless motor.
