Methods, systems, apparatuses, and computer-readable media for controlling components connected to and/or otherwise associated with a data bus are presented. According to one or more aspects of the disclosure, a plurality of processing devices having data bus management capability and at least one data bus associated with the plurality of processing devices may be identified. Subsequently, an inter-processor communication (IPC) layer for communication between the plurality of processing devices and the at least one data bus may be established over a messaging layer utilized by the at least one data bus. At least one component associated with the at least one data bus may then be controlled via the IPC layer using at least one of the plurality of processing devices.

Techniques are disclosed for utilizing a non-ported generic device (NGD) or other non-ported hardware to couple processing device(s) to access components on a serial data bus without the need for integrated manager hardware. Using the NGD, a processing device(s) can utilize available unused bandwidth on the serial data bus to communicate with components coupled with the serial data bus, including a processing device having the manager hardware. Various alterations and embodiments are disclosed.

Non-ported generic device (software managed generic device)

One embodiment of the invention comprises a non-transitory, tangible computer readable storage medium encoded with processor readable instructions to perform a method of transferring SDIO data. One method comprises buffering multiple IP packets to transfer from one of a SDCC host and a SDIO client to the other of the SDCC host and the SDIO client. A multiplexing header is attached to each of the multiple IP packets and one of at least one SDIO read command and at least one SDIO write command issued. The multiple IP packets are then transferred in a single SDIO transfer between the one of a SDCC host and a SDIO client to the other of the SDCC host and the SDIO client.

Method and apparatus for transferring data

A domain power notification system detects when a power domain experiences a power condition, such as lost power and low-voltage power, and communicates that information to the domains that communicate with the problem domain. As a result, the effected domains stop communicating with the problem domain without passing erroneous information.

System and method for domain power monitoring and notification

An apparatus and method is disclosed for initiating a sleep state in a system-on-a-chip (SOC) device. The apparatus comprises a bus controller coupled to a central processing unit (CPU) and a power management controller that is coupled to the bus controller and to a plurality of SOC modules. The power management controller sends control signals to the bus controller and to the SOC modules to coordinate the shutting down of power to the SOC modules during a process in which the power management controller places the SOC modules of the system-on-a-chip (SOC) device into a sleep state.
