摘要:
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. By using a relatively small number of RF communication modules, the present invention implements a wireless mobile multimode communication terminal which enables various operation modes including the MIMO operation mode. Compared with the existing solutions, the present invention greatly reduces the size required by the terminal.
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.
