    摘要： A method and an apparatus are provided. The apparatus is a hardware module that controls a power mode of a plurality of modules. The apparatus receives an indication of a desired operational frequency. Based on the received indication, the apparatus determines to switch from a first power mode associated with a first set of modules to a second power mode corresponding to the desired operational frequency and associated with a second set of modules. The apparatus enables modules in the second set of modules that are unassociated with the first power mode, stops traffic through the plurality of modules upon expiration of a time period after enabling the modules in the second set of modules that are unassociated with the first power mode, routes traffic through the second set of modules, and disables modules in the first set of modules that are unassociated with the second power mode.

    摘要： Methods and implementation of low-power power-on control circuits are disclosed. In a particular embodiment, a computer readable tangible medium stores instructions executable by a computer. The instructions may be executable by the computer to determine whether a power detector circuit powered by a first voltage supply has received a test input from at least one voltage level-shifting device coupled to a second voltage supply.
