  • Patent number: 8675785
    Abstract: One aspect of the present invention concerns the management of processing resource allocations for a Turbo receiver, where such resources are consumed from a finite resource budget within a defined processing time interval. The contemplated Turbo receiver attempts to allocate more processing resources to those demodulation and/or Turbo decoding tasks that make more valuable contributions with respect to the ultimate goal of successfully decoding all data streams that are of interest in a received signal. The advantageous management approach allows the Turbo receiver to obtain better results for a given consumption of processing resources, and further permits the Turbo receiver to quit upon either achieving a successful outcome within a defined processing time interval or exhausting the budgeted resources.

  • Patent number: 8549630
    Abstract: A method of securing bus architecture from a Trojan attack. A restricted address access detector generates an unauthorized access detection signal when a master ID signal is within a restricted range. The unauthorized access detection signal disables the requested slave select signal, and the address decoder instead outputs a default slave select signal. A counter determines the duration of a lock signal from a master, and a comparator activates a malicious bus lock signal if the lock signal duration exceeds a threshold. The master mask register forcibly gates the lock signal upon receipt of the malicious bus lock signal. If the duration of a wait request from a slave exceeds a maximum duration register value, a comparator activates a malicious wait detection signal to disable the wait request signal. The method might include storing identifying information about the malicious master and storing a slave ID corresponding to the malicious slave.

  • Patent number: 8503575
    Abstract: A pulse response for a receiver, as an array PR, is found from the receiver's symbol stream. For a continuous stream of arbitrary data, a value of the array PR[k] can be determined from the signal levels of the symbols received. The stream of received data is input to a FIFO. Between the first and last locations of the FIFO is the symbol referred to herein as Dn. Symbols located in the FIFO before Dn are referred to as Dn?x. Symbols located in the FIFO after Dn are referred to as Dn+x. Dn differs from the other FIFO symbols in that its signal level can be measured with an adjustable error slicer. The ISI effect of any Dn?k upon Dn can be measured, and thus any PR[k] measured, by measuring the average signal level of Dn when only certain types of data streams occur in the FIFO.

For example, in this embodiment, the method increases the accuracy of the estimation of the transmitted information, or similarly, increases the probability of making the correct estimates of the transmitted information, even in the presence of temporary severe levels of impairment. The channel fidelity history may also be stored and catalogued for use in, for example, future optimization of the transmit waveform.

  • Patent number: 8413034
    Abstract: In a magnetic data processing device, an input part sequentially receives magnetic data output from a magnetic sensor. A storage part stores a plurality of the magnetic data as a data set of statistical population. An index derivation part derives a distribution index of the data set of the statistical population. A reliability determination part determines whether or not reliability of the data set of the statistical population is acceptable based on the distribution index and a decision criterion. A decision criterion setting part increases strictness of the decision criterion when the reliability determination part determines that the reliability of the data set of the statistical population is acceptable, and decreases the strictness of the decision criterion when the reliability determination part determines that the reliability of the data set of the statistical population is unacceptable.

  • Patent number: 8312554
    Abstract: A data protecting method for a portable memory storage apparatus is provided. The method includes determining whether a mode signal is at a data protecting mode, and performing a file hiding procedure to change a file allocation table if the mode signal is at the data protecting mode, wherein a host system coupled to the portable memory storage device is allowed to only access a portion of logical addresses of the portable memory storage apparatus according to the changed file allocation table and files stored in the portable memory storage apparatus before the file hiding procedure are written into another portion of the logical addresses. Additionally, the method still includes performing a file showing procedure to change the file allocation table if the mode signal is not at the data protecting mode, wherein the host system may access all the logical addresses according to the changed file allocation table.

  • Patent number: 8205136
    Abstract: A method of handling a stuck bit in a directory of a cache memory, by defining multiple binary encodings to indicate a defective cache state, detecting an error in a tag stored in a member of the directory (wherein the tag at least includes an address field, a state field and an error-correction field), determining that the error is associated with a stuck bit of the directory member, and writing new state information to the directory member which is selected from one of the binary encodings based on a field location of the stuck bit within the directory member. The multiple binary encodings may include a first binary encoding when the stuck bit is in the address field, a second binary encoding when the stuck bit is in the state field, and a third binary encoding when the stuck bit is in the error-correction field. The new state information may also further be selected based on the value of the stuck bit, e.g.

  • Patent number: 8191074
    Abstract: A first code module in a computing device detects an event that constitutes an automatic start debug session condition. The detected event is an occurrence of significance to the first code module and the condition is a set of one or more start criterions of which the detected event is a part. One or more actions for that condition are determined, wherein each action includes properties of a different debug session. At least one of the action(s) are sent to a second code module in the computing device upon determining that the second code module should automatically start at least one debug session. One or more debug flags are set according to each action to start the debug session corresponding to each action and a set of debug messages corresponding to the flags that are set are generated.

  • Publication number: 20110314229
    Abstract: Aspects of the subject matter described herein relate to error detection for files. In aspects, before allowing updates to a clean file, a flag marking the file as dirty is written to non-volatile storage. Thereafter, the file may be updated as long as desired. Periodically or at some other time, the file may be marked as clean after all outstanding updates to the file and error codes associated with the file are written to storage. While waiting for outstanding updates and error codes to be written to storage, if additional requests to update the file are received, the file may be marked as dirty again prior to allowing the additional requests to update the file. The request to write a clean flag regarding the file may be done lazily.

  • Patent number: 8068564
    Abstract: Systems and methods are disclosed for detecting temporary high level impairments, such as noise or interference, for example, in a communications channel, and subsequently, mitigating the deleterious effects of the dynamic impairments. In one embodiment, the method not only performs dynamic characterization of channel fidelity against impairments, but also uses this dynamic characterization of the channel fidelity to adapt the receiver processing and to affect an improvement in the performance of the receiver. For example, in this embodiment, the method increases the accuracy of the estimation of the transmitted information, or similarly, increases the probability of making the correct estimates of the transmitted information, even in the presence of temporary severe levels of impairment. The channel fidelity history may also be stored and catalogued for use in, for example, future optimization of the transmit waveform.
