For example, a first Bluetooth (BT) device may be configured to operate in a role of a peripheral device over a BT link between the first BT device and a second BT device; and to initiate a role switch to switch the first BT device from the role of the peripheral device to a role of a central device over the BT link between the first BT device and the second BT device, based on a determination that the BT link between the first BT device and the second BT device is to be operated as an audio link to communicate audio data between the first BT device, as an audio source, and the second BT device, as an audio sink.

A system on a chip (SoC) includes a first domain comprising a first processor configured to boot the SoC, and a first debug subsystem, a second domain comprising a second processor, the second domain configurable as either a safety domain or a general-purpose processing domain, and isolation circuitry between the first domain and the second domain. During boot-up of the SoC, the first processor provides code to the second domain which, when executed by the second processor, configures the second domain as either a safety domain or as a general-purpose processing domain.

Certain aspects of the disclosure relates to a method for operating an electronic device. A control device detects a Universal Serial Bus (USB) interface being connected to the electronic device, where the USB interface has a plurality of virtual ports. Then the control device receives one or more descriptors through the USB interface, each descriptor corresponding to a function of the electronic device. Then the control device matches each descriptor corresponding to each function with one driver file corresponding to each function, and after the matching is successful, determines a virtual function device corresponding to execution of each function. In response to receiving an operating command for executing one function, the control device sends the operating command to the corresponding virtual function device to the function to be executed through a corresponding driver interface, such that the corresponding virtual function device is operated on the electronic device.

A method is described. The method includes executing solid state drive program code from system memory of a computing system to perform any/all of garbage collection, wear leveling and logical block address to physical block address translation routines for a solid state drive that is coupled to a computing system that the system memory is a component of.

The present disclosure relates to a system capable of verifying an external device control function of a secondary battery management device, and that is coupled with an input/output terminal unit, a communication terminal unit and a measurement terminal unit of the secondary battery management device. The system generates conditions causing operation of the external device, monitors whether an external device control signal is being output normally through the input/output terminal unit of the secondary battery management device, and verifies whether current operation state information for the external device is being maintained exactly in a memory element. The system may include an interface unit to convert the format of the data being transmitted between the computer and the secondary battery management device, and a voltage simulator capable of artificially generating a voltage signal representing the voltage, current and temperature level of the secondary battery and applying the same to the measurement terminal unit.

A communications link between a computing device and an external device is monitored. A driver for the communications link is executed on the computing device. The driver is configured to monitor data traffic over the communications link. Data indicative of the monitored data traffic is received from the driver. The data is sent to an analysis function configured to identify a condition of the communications link based on accumulated data indicative of the data traffic. Data indicative of an identified condition of the communications link is received from the analytics function. An indication of the identified condition is rendered on a display device of the computing device.

An image processing device and control method that includes a processor and a memory storing a set of instructions that, when executed by the processor, controls the image processing device to receive a first data object representing a software update to be applied to the at least one peripheral device coupled to the image processing device. A communication mode switch message is generated to change a mode of communicating data between the at least one peripheral device and the image processing device and communicate the communication mode switch message to the at least one peripheral device. Currently active communication mode is disabled and a previously disabled communication pathway of the at least one peripheral device is activated as an update mode. The data representing the software update is transmitted via the update mode to apply the software update to the at least one peripheral device.

Methods and apparatus for dynamic instruction set selection for producing an output parameter based on one or more available input parameters are presented. In an example method, a device selects, from different candidate instruction sets that are each configured to produce a same output parameter, an instruction set that requires one or more input parameters that are each available at the device. In addition, in the example method, the device obtains the output parameter by executing the selected instruction set using the input parameters required by that instruction set. In some examples where more than one candidate instruction sets could be selected based on the available input parameters, the device may select the highest-ranking instruction set for execution.

An electronic device includes a control circuit and a bus interface. The control circuit packs a plurality of commands in a compound command frame. The bus interface communicates with another electronic device via a bus between the electronic device and the another electronic device, and packs the compound command frame in a single packet and transmits the single packet over the bus.
