Abstract: An accelerator includes a memory, a compute zone to receive an encrypted workload downloaded from a tenant application running in a virtual machine on a host computing system attached to the accelerator, and a processor subsystem to execute a cryptographic key exchange protocol with the tenant application to derive a session key for the compute zone and to program the session key into the compute zone. The compute zone is to decrypt the encrypted workload using the session key, receive an encrypted data stream from the tenant application, decrypt the encrypted data stream using the session key, and process the decrypted data stream by executing the workload to produce metadata.

Abstract: A method for processing audio data includes determining a first common scalefactor value for representing quantized audio data in a frame. A second common scalefactor value is determined for representing the quantized audio data in the frame. A line equation common scalefactor value is determined from the first and second common scalefactor values.

Abstract: According to one embodiment of the present invention, a novel method and system are disclosed. In one embodiment, a first node records a first node local time of receiving a wirelessly transmitted packet, the first node local time recorded with a monotonically increasing clock of the first node. The first node wirelessly transmits the recorded local time to at least a second node. The second node records a second node local time of receiving the wirelessly transmitted packet and records the first node local time of receiving the wirelessly transmitted packet. The second node updates a second node timing model to synchronize with the first node, the updating based on the second node local time of receiving the wirelessly transmitted packet and the first node local time of receiving the wirelessly transmitted packet.

Abstract: According to one embodiment of the present invention, a novel method and system are disclosed. In one embodiment, an I/O device of a system receives or outputs a multimedia stream, the I/O device having a I/O clock and the system having a system clock. Samples from the multimedia stream are synchronized with the system clock.

Abstract: In one embodiment, spatial audio rendering is achieved by dividing a digitally formatted audio signal into a plurality of time-overlapping windows. The windows may be converted into the frequency domain. Frequency-domain windows are stored in respective cyclical buffers. Windows corresponding to identified reverberation paths are selected and processed (e.g., filtered) according to the characteristics of the respective reverberation path. Processed frequency-domain windows are accumulated and transformed back to the time domain. In one embodiment, head-related transfer functions (HRTFs) are imposed on the frequency-domain windows as a component of the processing.
