  • Patent number: 8983533
    Abstract: A method for enabling a MIMO operation mode in a multimode communication terminal includes switching a first channel module to have parameter characteristics consistent with those of a second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The method also includes extracting corresponding parameters from the second channel module and configuring the first channel module to be switched with the extracted parameters, such that the first channel module and second channel module enable the multimode communication terminal to perform MIMO communication. The method further includes issuing, upon determination of a switch, notification instructions to means in channel switch layer means and changing a data channel associated with the first channel module, such that the first channel module and second channel module can be adapted to the MIMO operation mode.

  • Patent number: 8302048
    Abstract: The present invention discloses a method and apparatus for detecting timing constraint conflicts, the method comprising: receiving a timing constraint file; taking all test points in the timing constraint file as nodes, determining directed edges between the nodes and weights of the directed edges according to timing constraints relevant to the test points in the timing constraint file to establish a directed graph; searching for all directed cycles of the directed graph; and for each directed cycle, if the sum of the weights of the directed edges constituting the directed cycle satisfies a required condition, determining that a timing constraint conflict exists among the test points and the timing constraints constituting the directed cycle. The method and apparatus can automatically detect timing constraint conflicts with one hundred percent to reduce design turnaround time and engineer resources in ASIC projects.

  • Patent number: 8195225
    Abstract: The present invention provides a multimode communication terminal which contains at least a first separate channel module and a second separate channel module. The multimode communication terminal can be configured to communicate by using the first channel module and/or the second channel module. The channel modules communicate according to different communication protocols. The multimode communication terminal further comprises: channel switch layer means for switching the first channel module to have parameter characteristics consistent with those of the second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The present invention further provides a method for enabling a MIMO operation mode in a multimode communication terminal.

  • Patent number: 8094706
    Abstract: Method, system and article of manufacture are provided for continually monitoring reliability, or aging, of a digital system and for issuing a warning signal if digital system operation degrades to or past a specified threshold. The technique includes periodically determining a maximum frequency of operation of the digital system, and generating a warning signal indicative of a reliability degradation of the digital system if at least one of: (i) a measured or estimated maximum frequency of operation of the digital system is below a warning threshold frequency of operation of the digital system, wherein the warning threshold frequency is greater than or equal to a manufacturer specified minimum frequency of operation for the digital system; or (ii) a rate of change in the difference between measured maximum frequencies of operation of the digital system exceeds an acceptable rate of change threshold for the digital system.
