Abstract:

An apparatus, method, and program product for optimizing core performance and power in a multi-core processor. The apparatus includes a multi-core processor coupled to a clock source providing a clock frequency to one or more cores, an independent power supply coupled to each core for providing a supply voltage to each core and a Phase-Locked Loop (PLL) circuit coupled to each core for dynamically adjusting the clock frequency provided to each core. The apparatus further includes a controller coupled to each core and being configured to collect performance data and power consumption data measured for each core and to adjust, using the PLL circuit, a supply voltage provided to a core, such that, the operational core frequency of the core is greater than a specification core frequency preset for the core and, such that, core performance and power consumption is optimized.

Abstract:

A locking device for securing golf clubs comprising at least two main elements: a base plate and a locking plate. The base plate has a plurality of notches formed on its outer periphery for receiving the shafts of one or more golf clubs. The locking plate with a plurality of hooks is rotatably mounted on the base plate. A golf club inserted into a notch is retained in place upon rotation of the locking plate. A lock mechanism can be added such that when it is engaged, it locks the plates against rotation.
