International Classification:

G06F 1300

US Classification:

710 52, 710 18, 710 53, 710 55, 710 56, 710 57, 710 61, 711744, 711775, 370235, 370360, 370394

Abstract:

In one embodiment of the present invention, an output device sends a spurious data sample in place of a first data sample to be sent from a queue if the queue is in a state of underflow during which the first data sample is not available to be sent. The buffer is to store data samples for an isochronous data transmission. Circuitry skips the first data sample when the first data sample becomes available in the queue so that synchronization for subsequent data samples sent from the queue is preserved. In another embodiment of the present invention, an input device advances an input buffer pointer to point to a next location in a memory in response to receiving a data sample at a queue during a state of overflow. The input buffer pointer indicates a location in the memory to which a next data sample is to be sent from the queue. The queue stores data samples for an isochronous data transmission.

International Classification:

G06F 12/14
G06F 11/30

US Classification:

713193, 713167

Abstract:

Secure storage and retrieval of a unique value associated with a device to/from a memory of a processing system. In at least one embodiment, the device needs to be able to access the unique value across processing system resets, and the device does not have sufficient non-volatile storage to store the unique value itself. Instead, the unique value is stored in the processing system memory in such a way that the stored unique value does not create a unique identifier for the processing system or the device. A pseudo-randomly or randomly generated initialization vector may be used to vary an encrypted data structure used to store the unique value in the memory.

Abstract:

A method and system to allow the secure configuration of the configurable feature(s) of a hardware device in a platform. The configuration of the configurable feature(s) of the hardware device is performed with protection against software attacks. A management module determines that the platform is authorized to configure at least one configurable feature of the hardware device and configures each of the configurable feature(s) based on a received configuration message.

International Classification:

G06F 9/24

US Classification:

713 2

Abstract:

In one embodiment, the present invention includes a method for obtaining a pre-boot authentication (PBA) image from a non-volatile storage that is configured with full disk encryption (FDE), and storing the PBA image in a memory. Then a callback protocol can be performed between a loader executing on an engine of a chipset and an integrity checker of a third party that provided the PBA image to confirm integrity of the PBA image, the PBA image is executed if the integrity is confirmed, and otherwise it is deleted. Other embodiments are described and claimed.
