  • Patent number: 8364988
    Abstract: The feature of the present invention consists in: a processor main circuit for executing program instruction strings on a processor chip; a substrate bias switching unit for switching voltages of substrate biases applied to a substrate of the processor main circuit; and an operation mode control unit for controlling, in response to the execution of an instruction to proceed to a stand-by mode in the processor main circuit, the substrate bias switching unit in such a way that the biases are switched over to voltages for the stand-by mode, and for controlling, in response to an interruption of the stand-by release from the outside, the substrate bias switching unit in such a way that the biases are switched over to voltages for a normal mode, and also for releasing, after the bias voltages switched thereto have been stabilized, the stand-by of the processor main circuit to restart the operation.

  • Patent number: 7289802
    Abstract: An acquisition section acquires trace information including a plurality of log information having information on contents and types of log information based on message information of test signals transmitted to a communication terminal and a series of reply signals from the communication terminals, and provides clock time information at which the respective message information have been acquired. The trace information including the plurality of log information, is displayed in predetermined formats. An indication bar display section displays an indication bar on which the plurality of log information are arranged in a time series based on the clock time at which the respective message information have been acquired. A log sequence display section displays a predetermined number of log information as log sequences having time stamps based on the clock time information at which the respective log information have been acquired, so as to be associated with the indication bar.
