  • Publication number: 20190272565
    Abstract: A system and method for displaying advertising contents on a portion of display screen of a mobile device. The display screen of the mobile device is divided into a first portion and a second portion, where a physical display driver of the display screen is configured to divide into two or more logical display drivers by a software application to drive the contents on the first portion and the second portion simultaneously. The first portion is a normal user initiated application display and the second portion is an advertising application display. The purpose of the present invention is that the advertising application display can be driven by any content by either the mobile device manufacturers (MDMs) or communication service providers (CSPs) or mobile virtual network operators (MVNOs). The portion of the advertising application display can be used for monetizing by the device manufacturers or the mobile operator for delivering the advertising content for advertisers.

  • Publication number: 20090222921
    Abstract: A system and method are disclosed for utilizing resources of a network. A constructive proof that a subset of resources is sufficient to satisfy the objective of a system can be generated. The constructive proof can comprise instructions for using the subset of resources. A set of computer-executable instructions can be created from the constructive proof and executed on a host device. The computer-executable instructions can control a data output device according to the instructions of the constructive proof.

  • Publication number: 20020069396
    Abstract: A system and method for designing ICs, including the steps of: analyzing and optimizing a target IC design based on design-specific objectives; partitioning the optimized target IC design into pre-defined standard-cells from one or more libraries and creating design-specific cells specifically having unique functionality and characteristics not found amongst the standard-cells; identifying and determining a minimal subset of the standard-cells and design-specific cells, the interconnection of which represents the target IC design; generating the necessary views, including layout and characterizing of the design-specific cells included in a unique, minimal subset, wherein the IC design is subject to objectives and constraints of the target IC.

  • Patent number: 5958077
    Abstract: A synchronous test model (STM) and corresponding method capture the essential behavior of an asynchronous circuit under test. During operation of the method, (1) An STM for the asynchronous circuit is constructed assuming either a user-specified cycle length or an estimated cycle length; (2) a target fault list is created containing only faults in the asynchronous circuit, (3) test patterns are generated from the STM using a synchronous test generator; (4) the test patterns are translated into test sequences for the asynchronous circuit; and (5) the translated patterns are validated by fault simulation on the asynchronous circuit.

  • Patent number: 5808917
    Abstract: Low power linear digital signal processing circuits are fabricated based on a design synthesis process using activity metrics. The average activity value .theta..sub.i of all the input nodes of the circuit is determined. Architectural transformations of the circuit are performed in order to minimize the average activity value over all the nodes. The transformation resulting in the minimum activity value is the synthesized design used as the basis for fabricating a low power linear digital signal processing circuit.

  • Patent number: 5513118
    Abstract: A method for performing high level synthesis of integrated circuits simultaneously considers testability and resource utilization. The method considers the relationship between hardware sharing, loops in the synthesized data path, and partial scan testing overhead. Hardware sharing is used to minimize the quantity of scan registers required to synthesize data paths with a minimal quantity of loops. A random walk based algorithm is used to break all control data flow graph (CDFG) loops with a minimal quantity of scan registers. Subsequent scheduling and assignment avoids the formation of loops in the data path by reusing the scan registers, while ensuring high resource utilization of the components of hardware costs: execution units, registers and interconnects. The partial scan overhead incurred is less than that of conventional gate level design partial scan techniques.

  • Patent number: 5502730
    Abstract: A method of selecting circuit elements in a sequential circuit for partial scan testing relies upon analyzing and breaking reconvergence through the selected circuit element. Different types of reconvergences present in the circuit and their affect on the circuit testability are considered. Harmful reconvergence present in the circuit are broken by scanning a memory element present in the reconvergence path.

  • Patent number: 5493505
    Abstract: A method of asynchronous circuit synthesis of initializable circuits from signal transition graphs (STG) that are either functionally initializable or functionally uninitializable is described. For functionally initializable cases, an initializable implementation can be achieved by proper assignment of don't care values. If the STG is not functionally initializable, the sources of uninitializability in the STG are identified and the STG is transformed into a functionally initializable specification by exploiting concurrency. Initializability is achieved at the expense of minimal removal of concurrency. Moreover, the transformation does not violate liveness and unique state coding properties of the STG. When the STG is functionally initializable or after an uninitializable STG is transformed to become functionally initializable the result is an initializable circuit design.
