摘要： System and method are provided for continually monitoring reliability, or aging, of a digital system and for issuing a warning signal if digital system operation degrades past a specified threshold. The technique includes implementing a ring oscillator sensor in association with the digital system, wherein logic and/or device percent composition of the ring oscillator sensor mirrors percent composition thereof within the digital system. Counter logic is coupled to the ring oscillator sensor for converting outputted count signals to an oscillation frequency, and control logic is coupled to the counter logic for periodically evaluating oscillation frequency of the ring oscillator sensor and generating a warning signal indicative of reliability degradation if at least one of: (i) a measured or estimated oscillation frequency is below a warning threshold frequency; or (ii) a measured or estimated rate of change in a difference between measured oscillation frequencies exceeds an acceptable rate of change threshold.

摘要： 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.
