Abstract: A voltage derived from accessing a selected bit using one read current may be utilized to read a selected bit of an untriggered phase change memory after the read current is changed. As a result, different reference voltages may be used to sense the state of more resistive versus a less resistive selected cells. The resulting read window or margin may be improved in some embodiments.

Abstract: A processing system to serve as a source device for protected digital content comprises a processor and control logic. When used by the processor, the control logic causes the processing system to receive a digital certificate from a presentation device. The processing system then uses public key infrastructure (PKI) to determine whether the presentation device has been authorized by a certificate authority (CA) to receive protected content. The processing system may also generate a session key and use the session key to encrypt data. The processing system may transmit the encrypted data to the presentation device only if the presentation device has been authorized by the CA to receive protected content. Presentation devices and repeaters may perform corresponding operations, thereby allowing content to be transmitted and presented in a protected manner. Other embodiments are described and claimed.

Other embodiments are described and claimed.

Abstract: A method of selectively sharpening an image may include, for at least some pixels in the image, determining a frequency content associated with a pixel value in the image. The pixel may be linearly sharpened if the frequency content exceeds a threshold. The pixel may be non-linearly sharpened if the frequency content does not exceed the threshold. In some implementations, the non-linear sharpening may include wavelet decomposition of the image and enhancement of decomposed components.

Abstract: A communications system includes a network that is coupled to a number of terminals, at least some of which are capable of audio or other forms of real-time interactive data communications over the network. Each of the terminals includes a network adapter that is capable of detecting a collision with another terminal on the network. If a collision is detected, transmission of a data frame is aborted, and a backoff time delay is selected. The backoff time delay is selected from a group of delay periods that vary at a rate different than exponentially with a number of collisions. The group of one or more delay periods can contain delay periods that increase linearly with the number of collisions, delay periods that increase according to some power of n, where n is the number of collisions, or a delay period that is selected at random based on a predetermined mean backoff delay.

Abstract: Apparatus, systems and methods for handling portrait mode oriented display surfaces without requiring expensive hardware in the display sub-system are disclosed. For example, an apparatus is disclosed such that the rendering of graphics data to the portrait mode display surfaces is redirected at rendering time such that there is no need for adding complicated hardware in the display part of the graphics adapter in order to handle conventional displays—all of which have no circuitry to deal with data natively stored in a portrait mode surface. Additionally, an apparatus to handle direct surface access of a surface through a surface lock which has already been rotated is already described. This can either be done by copying of surface data or by an optimized proposed apparatus which eliminates this copy. Other implementations are also disclosed.

Abstract: In one embodiment, the present invention includes a method for determining process corner information of an integrated circuit (IC) and controlling at least one analog current for at least one analog circuit of the IC based on the process corner information. More specifically, if the process corner information is indicative of a fast corner IC, the analog current may be scaled down. At the same time that the analog current is scaled down, a current consumption level of digital circuitry of the IC may increase. In this way, overall power consumption of the IC may be reduced to the extent that the analog current(s) are scaled.

Abstract: In one embodiment, the present invention includes a method for accessing registers associated with a first thread while executing a second thread. In one such embodiment a method may include preventing an instruction of a first thread that is to access a source operand from a register file of a second thread from executing if a synchronization indicator associated with the source operand indicates incompletion of a producer operation of the second thread, and executing the instruction if the synchronization indicator indicates completion of the producer operation of the second thread. Other embodiments are described and claimed.

Abstract: A database system is capable of processing a query and providing a progress indicator of the processing of the query based on at least a first cost factor. Initially, an estimate is set for the first cost factor. During processing of the query, the estimate of the first cost factor is updated to enable refinement of the progress indicator.

Abstract: A femtocell may be initialized on a network by automatically contacting a network service provider. The access point then automatically downloads an initial configuration from a bootstrap server belonging to the network service provider. In some cases, a femtocell access point may automatically determine, after boot up, whether it was pre-provisioned with credentials to authenticate itself with the network service provider. If so, it may use a domain name service to obtain an address of a bootstrap server. Otherwise, it may use dynamic host configuration protocol to discover the bootstrap server's Internet Protocol address.

This configurable front end may be differently controlled depending on a particular radio implementation in which the tuner is adapted.
