摘要： Systems and methods for audio streaming in a computing device are described. In one aspect an interface to an adapter driver is provided. The adapter driver is associated with an audio device. The adapter driver and a wave real-time (WaveRT) port driver associated with the computing device use the interface to configure direct access by a client of the computing device and by the audio device to a cyclic buffer. The direct access is for rendering and/or capturing an audio stream. The direct access is independent of any copying by a port driver on the computer system of the audio stream to any buffer.

摘要： Systems and methods for equal opportunity bandwidth regulation are described. In one aspect, data is received from a transmitting entity of one or more transmitting entities. Responsive to receiving the data, the data is transmitted across a bus to a target entity. This transmission is accomplished by dynamically regulating data transmission bandwidth on the bus such that each data transmitting entity of the transmitting entities has a substantially equal opportunity to have bus bandwidth allocated to transmit data associated with the data transmitting entity.

摘要： Among other disclosed subject matter, a system includes a secure execution domain configured to execute trusted processes. The system also includes a hardware virtualization component in the secure execution domain and configured to implement a virtual machine. The virtual machine is a hardware virtualization of a data processing apparatus and includes a shared virtual memory device and a guest software application coupled to the shared virtual memory device. The system also includes a trusted process in the secure execution domain, separate from the virtual machine and coupled to the shared virtual memory device. The trusted process is configured to communicate with the guest software application through the shared virtual memory device. Communication with the guest software application includes secure communication.

摘要： Systems and methods for interfacing with codec(s) on an architecture optimized for audio are described. In one aspect, a device driver accesses an application programming interface (API). The API facilitates communications between the device driver and one or more codec(s) via a controller coupled to the codec(s). The codec(s) and the controller are implemented in an environment that is substantially optimized for audio. Such communication includes, for example, registering for event(s), transferring data to or from the codec(s), obtaining information about the capability of the codec(s), and/or managing bus or codec resources.

摘要： Systems and methods for managing input ring buffer data transfers are described. In one aspect, a set of data packets from an output ring buffer (ORB) are sent to a codec. Information associated with the data packets is provided by a device driver. The data packets are stored in the ORB. The device driver is notified of any invalid response corresponding to a data packet of the data packets.
