Abstract: Each match line of a memory device such as a content addressable memory (CAM) device and a related part of a priority encoder can be separately tested. In test mode, all match lines are first reset/disabled. A write enable pulse signal enables a match line corresponding to a CAM word line at a decoded address to be gated to the priority encoder of the CAM device. The CAM memory storage location and the comparand register are each loaded with the same test entry. A search is performed for the test entry. If the enabled match line is asserted and the priority encoder outputs the address corresponding to the CAM memory storage location, the test is successful. If not there is a match line error or a defect in the priority encoder.

Abstract: An intelligent streaming media error check detection method and apparatus. The claimed embodiment discloses an apparatus and method where all streaming media are initially assumed to have compatible error checksums. A parameter W is initialized to zero. The parameter W is not constant and conceptually represents a state of the error check method. The destructive value of a first predefined constant is added to the parameter W each time the acceptability of a data set cannot be verified. The constructive value of a second predefined constant is subtracted from the parameter W each time the acceptability of a data set is successfully verified. If the value of the parameter W equals or exceeds a predefined threshold, the remainder of the streaming media is decoded and played without error check protection.

Abstract: The present invention is an error detection and correction scheme that enables the use of Horner's algorithm for the computation of EDC syndromes from the computed error pattern. Specifically, “transformed” EDC syndromes are computed during the read back of data and parity from the medium. The transformed syndromes are values of the polynomial whose coefficients occur in reverse order from that of the EDC codeword polynomial. In essence, by reversing the order of the coefficients, the Chien search processes the terms in descending order which is the right direction for Horner evaluation.

Abstract: A data detection and decoding system in which a single parity bit added to the end of each code word by the encoder is used in the channel detector to improve the accuracy with which bit decisions are made in the channel detector. The bit estimates and the reliability estimates are then processed by the decoder to recover the original input bits. By using single parity for this dual purpose in combination with a decoder that follows the channel detector and uses the bit estimates and reliability estimates to recover the original input bits, performance of the data detection and decoding system is greatly improved while also overcoming the disadvantages of known digital recording systems.

Abstract: Systems and methods for interfacing with playback of media by a media player are provided. By combining the functionality of fast forward and skip forward into a single button control, the invention reduces the numbers of control buttons that need be included on a device, reducing device costs and consumer “button overload.” In one embodiment, by pressing (and releasing) a forward button, media being rendered by a media player skips to a predetermined location in the media. By pressing and holding (and then releasing) the forward button, the media being rendered is fast forwarded according to algorithms for fast forwarding. A backward button covers skipping backward and fast reversing in a similar fashion. A device including a play/pause button and the described forward and backward buttons advantageously reduces the number of buttons required by two buttons.

Abstract: In a single window browser environment, a request to open a new browser window is either allowed or ignored, depending on whether the request was generated in response to user input. The request is ignored if it was not generated in response to user input. If, on the other hand, the request was generated in response to user input, it is allowed. In such cases, in order to preserve the single window interface, the new browser window is opened as a full screen window that overlays the existing browser window. In certain implementations, the determination of whether or not a request was generated in response to user input is simplified by assuming that all requests that are generated during the loading or unloading of a page are not in response to user input and ought to be ignored. By contrast, window open requests that are generated at other times are assumed to be user-initiated and are allowed.

Abstract: A property used in functional verification of a circuit design is debugged independently of the circuit design for which the property is intended. Visualization of the property under various conditions helps a user to debug any errors in how the property is implemented in a requirements model. To visualize a particular property, a trace of a corresponding property in the requirements model is generated. The trace illustrates waveforms of a set of signals related to the property for a number of clock cycles. To visualize the property under various conditions, a user can find additional traces of the property by applying visualization constraints to obtain meaningful traces.

Abstract: A method for generating a constraint for use in the verification of an integrated circuit design includes identifying a target in a netlist (N) of the design and creating an overapproximate abstraction (N?) of the netlist. A space state (S?) is created by enumerating the states of N? from which the identified target may be asserted. A constraint space C? is then derived from the state space S?, where C? is the logical complement of S?. The process is repeated for multiple selected targets and the constraint spaces from each iteration are logically ANDed. Creating an overapproximate abstraction may include replacing a sequential gate with a random gate. Identifying a sequential gate may include selecting a target in the netlist, performing underapproximate verification of the target, and, if a spurious failure occurs, selecting a gate further down the fanin chain of the currently selected gate.

Pruning the signal flow graph also includes determining if any remaining non-visited neighbor vertices remain to be analyzed. If any remaining non-visited neighbor vertices remain to be analyzed then selecting a neighboring vertex and determining if the selected neighbor vertex is identified as a sensitivity path.
