Abstract: Certain embodiments of the invention may include systems, methods and apparatus for voltage clamp circuits. According to an example embodiment of the invention, a voltage clamp circuit may include a first circuit portion electrically coupled to the output of at least one power source. The first circuit portion comprises a power semiconductor device having a first, second and third node and one or more zener diodes electrically coupled to the first or the second node of the power semiconductor device. The voltage clamp circuit may further include a second circuit portion in electrical communication with the first circuit portion, where the second circuit portion comprises a resistor, a capacitor and a directional device, and where the second circuit portion connects to the one or more zener diodes to reduce peak voltage output between the second and the third node of the power semiconductor device.

Abstract: Techniques for detecting rolling reboots and for taking responsive actions to stop rolling reboots.

Abstract: A link based system including a plurality of processors is reset when transitioning from a slower speed to a higher speed mode during a booting process. One processor may coordinate the simultaneous establishment of link resetting of a plurality of other processors. In one embodiment, the processors may operate beginning with the farthest processor to reset their local links. Each processor sets its local links and if it determines, based on the speed of the link that the link has already been reset, it moves on to the next link.
