A spring-loaded rotatable support integrated into the end of a cable modem housing can be deployed to prevent tipping of the modem housing when it is placed in the vertical position, and stowed to allow placement of the modem in a horizontal position. The audio processing device comprises: a first receiving module, configured to receive a first audio signal; a second receiving module, configured to receive a second audio signal; an audio synthesizing module, configured to synthesize the first audio signal and the second audio signal to obtain a third audio signal; and an audio outputting module, configured to output the third audio signal. The logic further: schedules the first memory access operations to the first memory rank for early completion relative to other memory access operations in the re-order queue that target other memory ranks; and performs the high priority, high latency operation at the first memory rank at the scheduled time. Otherwise, further analysis, informed by the results if the initial complete spectral analysis, is performed. The second diffusion region is connected to a program and erase bit line.
