摘要: Described is an apparatus having a non-linear control to manage power supply droop at an output of a voltage regulator. The apparatus comprises: a first inductor for coupling to a load; a capacitor, coupled to the first inductor, and for coupling to the load; a first high-side switch couple to the first inductor; a first low-side switch coupled to the first inductor; a bridge controller to control when to turn on and off the first high-side and first low-side switches; and a non-linear control (NLC) unit to monitor output voltage on the load, and to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a voltage droop is detected on the load.

摘要: Methods and apparatuses provide voltage regulation for a processor. Control or configuration parameters for a voltage regulator (VR) are provided digitally over a configuration bus to a VR controller. The parameters may be provided directly from a storage element, or via a processing element or processor core. Based in whole or in part on the parameters, the VR controller provides an output control signal to affect a power output from a power converter to the processing element. In one embodiment, the VR controller is integrated onto the same IC as the processing element.

摘要: A clock generating circuit is provided that includes a multiplexing device coupled to a clock distribution network to select between a synchronous mode and an asynchronous mode. The device may also include a plurality of distributed ring oscillators to drive the clock distribution network in the asynchronous mode. In the synchronous mode, the multiplexing device may pass a signal from a phase lock loop circuit located external to a core.

摘要: A high-speed low-power-consumption two-input arbiter circuit comprises two input inverters, two inverters cross-coupled to form a latch and two additional inverters that drive a difference detector. The detector responds only to a voltage difference on its inputs that exceeds a specified value. In this way, signals are blocked from appearing at the outputs of the detector while the latch is in a metastable state. Additionally, an n-input arbiter circuit comprises (n-1)+(n-2)+ . . . +[n-(n-1)] two-input arbiter circuits and logic circuitry connected to the outputs of the two-input circuits for supplying a priority signal to one and only one at a time of n output terminals of the n-input circuit.

摘要: A voltage translator containing a bipolar transistor (Q1), a rectifier (10), a resistor (R1), and a first clamp (12) converts an input voltage (V.sub.I) into one or more output voltages of restricted voltage swing. The first clamp clamps the emitter voltage of the transistor when it is turned on. In one version, the translator includes a second clamp (14) that clamps the collector voltage of the translator when it is turned off. The translator then provides an output voltage (V.sub.O) inverse to the input voltage. In another version, the first clamp is connected between a voltage supply (V.sub.EE) and the emitter of the transistor. Its collector is connected directly to another voltage supply (V.sub.CC) so that the translator only makes non-inverting translations.
