Abstract:
Systems and methods are described that comprise receiving at a platform an enrollment request from a client device. The enrollment request comprises a request key and device data of the client device. Device identification is generated and issued to the client device in the absence of a previous enrollment event. A response to the client device is generated, and the response is a response to the enrollment request that includes the device identification. Subsequent sessions between the client device and the platform are controlled with the device identification.
Abstract:
A coherency controller, such as one used within a system-on-chip, is capable of issuing different types of snoops to coherent caches. The coherency controller chooses the type of snoop based on the type of request that caused the snoops or the state of the system or both. By so doing, coherent caches provide data when they have sufficient throughput, and are not required to provide data when they do not have insufficient throughput.
Abstract:
A simple format is disclosed and referred to as Elementary Network Description (END). The format can fully describe a large-scale neuronal model and embodiments of software or hardware engines to simulate such a model efficiently. The architecture of such neuromorphic engines is optimal for high-performance parallel processing of spiking networks with spike-timing dependent plasticity. Methods for managing memory in a processing system are described whereby memory can be allocated among a plurality of elements and rules configured for each element such that the parallel execution of the spiking networks is most optimal.
Abstract:
An apparatus configured to determine an approximate position of an object utilizing mutual-capacitance sensing capabilities during a first mode of operation and determining one or more attributes of the object utilizing self-capacitance sensing capabilities during a second mode of operation is disclosed. The apparatus includes a touch panel controller configured to operatively couple to a touch panel sensor. The touch panel sensor includes a plurality of drive electrodes and at least one sense electrode. A plurality of nodes are formed at the intersections of the plurality of drive electrodes and the at least one sense electrode. The touch panel controller is configured to determine an approximate position of an object performing a touch event over the touch panel sensor during the first mode of operation and to determine one or more attributes of the object during the second mode of operation.
Abstract:
A simplified coherency controller supports multiple exclusively active fully coherent agent interfaces and any number of active I/O (partially) coherent agent interfaces. A state controller determines which fully coherent agent is active. Multiple fully coherent agents can be simultaneously active during a short period of a transition of processing from one to another processor. Multiple fully coherent agents can be simultaneously active, though without a mutually consistent view of memory, which is practical in cases such as when running multiple operating systems on different processors.
Abstract:
A method, apparatus, and manufacture for smiling face detection is provided. For each frame, a list of new smiling faces for the frame is generated by performing smiling face detection employing an object classifier that trained is to distinguish between smiling faces and all objects in the frame that are not smiling faces. For the first frame, the list of new smiling faces is employed as an input smiling face list for the next frame. For each frame after the first frame, a list of tracked smiles for the frame is generated by tracking smiling faces in the frame from the input smiling list for the frame. Further, a list of new smiling faces is generated for the next frame by combining the list of new smiling faces for the frame with the list of tracked smiles for the frame.
Abstract:
Improved face tracking is provided during determination of an image by an imaging device using a low power face tracking unit. In one embodiment, image data associated with a frame and one or more face detection windows from a face detection unit may be received by the face tracking unit. The face detection windows are associated with the image data of the frame. A face list may be determined based on the face detection windows and one or more faces may be selected from the face list to generate an output face list. The output face list may then be provided to a processor of an imaging device for the detection of an image based on at least one of coordinate and scale values of the one or more faces on the output face list.
Abstract:
The present invention provides a transaction interface to be used between semiconductor intellectual property cores. The urgency attribute of pending transactions can be changed by a special type of transaction at the interface. The urgency can be incremented, raised to at least an indicated value, or changed to a value as specified. For an interface with multiple pending transactions, a mask can be used to indicate one or more IDs, the transactions of which should be changed.
Abstract:
A cache coherency controller, a system comprising such, and a method of its operation are disclosed. The coherency controller ensures that target-side security checking rules are not violated by the performance-improving processes commonly used in coherency controllers such as dropping, merging, invalidating, forwarding, and snooping. This is done by ensuring that requests marked for target-side security checking and any other requests to overlapping addresses are forwarded directly to the target-side security filter without modification or side effects.
Abstract:
A method for determining noise levels in a subband of an image. The method comprises receiving the subband of the image, defining block regions in at least two space domains of the subband, for each defined block region, identifying first wavelet coefficients associated with coordinate values in the at least two space domains in the defined block region, computing a correlation matrix between identified wavelet coefficients to determine the correlation between first wavelet coefficients according to the at least one color domain, computing second wavelet coefficients, the computation of second wavelet coefficients being based on the correlation matrix and the first wavelet coefficients, computing at least one noise level, the noise level computation being based on at least one second wavelet coefficient and providing the at least one noise level.
