Some demonstrative embodiments include devices, systems and methods of communicating acoustic information of a distributed microphone array between mobile devices. For example, an audio processor may determine source information of one or more acoustic sources based on acoustic information sensed by a distributed microphone array including a first microphone of a first mobile device and a second microphone of a second mobile device.

Techniques for audio synchronization are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an audio synchronization module, and the audio synchronization module may be operable by the processor circuit to receive audio information comprising a first network time index defined with respect to a network clock for a network, determine a second network time index for the audio information, the second network time index defined with respect to the network clock, determine a transmission delay value for the audio information based on a difference between the first network time index and the second network time index, and determine a total delay value for the audio information based on the transmission delay value and on a remote processing delay value for the audio information. Other embodiments are described and claimed.

Systems and methods are directed to a memory device that includes a plurality of memory buffers and a direct memory access (DMA) descriptor structure. The DMA descriptor structure comprises a transfer command and associated data transfer information and encryption/decryption information that is configured in a two dimensional, tree-linked structure. A DMA controller that is communicatively coupled to the memory device transfers data to/from the memory buffers and encrypts/decrypts the data based on the transfer command and data transfer information and encryption/decryption information provided by the two dimensional, tree-linked DMA descriptor structure.

Embodiments may comprise logic such as hardware and/or code to assign or offload Bluetooth applications from the main processor while maintaining the legacy interface to the OS protocol stack and compatibility to legacy Bluetooth applications. Embodiments may comprise selection logic such as a multiplexer in the Bluetooth radio controller to allow it to support multiple Bluetooth core stacks. The selection logic may enable offloading specific applications to an additional stack, such as an embedded stack while supporting the operating system (OS) stack in parallel. Embodiments may also comprise a Bluetooth radio controller with one or more additional host interface drivers to support multiple Bluetooth core stacks.
