Adaptive lock time controller for a frequency synthesizer and method therefor

Abstract: An adaptive lock time controller for a phase locked loop having dividers for generating first and second loop timing signals, a phase detector, a voltage controlled oscillator, and a charging circuit for generating at least a first control signal for converging the output frequency to one or more predetermined frequency channels and a second control signal for maintaining the output frequency substantially constant, comprises a synchronization generator, a phase lock detector, and a control signal selector. The synchronization generator is responsive to the phase detector for synchronizing the phase lock detector. The phase lock detector detects phase locked and unlocked conditions by generating a count representative of the phase difference between the first and second loop timing signals. When the count generated exceeds a predetermined count, a phase locked condition exists, otherwise the loop is unlocked. The control signal selector selects the first control signal during the predetermined time interval when the phase unlocked condition is detected, and the second control signal when the phase locked condition is detected.

Virtual machine extended capabilities using application contexts in a resource-constrained device

Abstract: Embodiments of the systems and methods utilize application contexts for extending virtual machines in a resource-constrained device to allow virtual machines to at least exercise scheduling control over platform independent applications and platform dependent native applications. Application contexts can be assigned to each application in the system. An application is represented by one or more data structures and functions. In one embodiment, an “application context” includes an interface to a virtual machine and a container for an execution environment of the application. The interface represents a mapping of services to an execution environment. The application context can isolate control over the execution of the application from the execution environment, thus, allowing the virtual machine to control execution of the application and allowing the application to be executed in a native environment, a virtual machine environment, or any other execution environment.

Method for Efficient CQI Feedback

Abstract: In a closed-loop wireless communication system ( 300 ), channel-side information—such as CQI information, rank adaptation information or MIMO codebook selection information—is fed back to the transmitter ( 310 ) in response to a start message ( 301 ) using a configurable or default time period or window by having the receiver ( 320 ) automatically terminate feedback upon expiration of the time period/window. The receiver ( 330 ) may continue or interrupt the feedback upon receipt of appropriate messaging (e.g., 306 ) from the transmitter ( 310 ).

Method and apparatus for encoding and decoding video signals by using storage and retrieval of motion vectors

Abstract: A system (10) which encodes and decodes video signals in accordance with a compression standard, such as H263, efficiently stores and retrieves motion vectors associated with the signals An encoder (16) and a decoder (22) each use a motion vector storage and retrieval circuit (38, 72) which addresses a respective SRAM array (52, 52′) Advanced Prediction Mode for a video signal is implemented by storing only a minimum number of motion vectors by eliminating storage of motion vectors which are not needed for a real-time current calculation Storage of selected top motion vectors associated with predetermined macroblocks of video information is avoided to gain a memory savings

Scribe street structure for backend interconnect semiconductor wafer integration

Abstract: A method of making a semiconductor device includes forming a wafer having a substrate and an interconnect structure over the substrate. The wafer also includes a plurality of die areas and a street located between a first die area of the plurality and a second die area of the plurality. A separation structure that includes metal is located in the interconnect structure. At least a portion of the separation structure is located in a saw kerf of the street. The separation structure is arranged to provide a predefined separation path for separating the first die area during a singulation process.
