Abstract:
PROBLEM TO BE SOLVED: To provide independent power control of two or more processing cores, more particularly, a technique to place at least one processing core in a certain power state without coordinating with the power state of one or more other processing cores in at least one embodiment. SOLUTION: A power control logic for controlling power consumption of a first processing core independently from a second processing core is provided. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
A method and apparatus is presented to allow one or more electrical components to be coupled to the land-side of an integrated circuit package coupled to a circuit board. In a first embodiment, a void is provided in the circuit board, and a peripheral area of the integrated circuit package is coupled to a peripheral area around the void. This provides space for the insertion of components in the land-side of the integrated circuit package. In a second embodiment, a spacer is provided coupled to the peripheral area of the integrated circuit package to allow the insertion of components into the land-side of the package and above the circuit board. With these embodiments of the present invention, components, such as decoupling capacitors can be coupled closer to the die (e.g. a processor die) of the package thus reducing parasitic inductance.
Abstract:
An improvement is presented for connecting conductive components of a built-up circuit board. Rather than using vias or micro vias to connect a conductive layer to a conductive component separated by an insulating layer (56,58), an elongated via (60a,60b,60c,62a,62b,62c) is used. In one embodiment, the elongated via (62a,62b,62c) has a length that is sufficient to directly coupled a first layer (57) to the edge of a via (60a,60b,60c) in a lower layer. Thus, it can be said that the elongated via "self-aligns" with the via in the lower layer. In doing so, electrical connections from one side of a circuit board to a component coupled to the other side of the circuit board are more direct leading to a reduction in parasitic induction.
Abstract:
Beschrieben ist eine Vorrichtung, die eine nichtlineare Steuerung zum Management des Leistungsversorgungsabfalls an einem Ausgang eines Spannungsreglers aufweist. Die Vorrichtung umfasst: eine erste Induktivität zum Koppeln mit einer Last; einen mit der ersten Induktivität gekoppelten Kondensator und zum Koppeln mit der Last; einen ersten mit der ersten Induktivität gekoppelten High-Side-Schalter; einen ersten mit der ersten Induktivität gekoppelten Low-Side-Schalter; eine Brückensteuerung zum Steuern, wann der erste High-Side-Schalter und der erste Low-Side-Schalter ein- und auszuschalten sind; und eine nicht lineare Steuerungseinheit (NLC) zum Überwachen der Ausgangsspannung an der Last und zum Veranlassen, dass die Brückensteuerung den ersten High-Side-Schalter einschaltet und den ersten Low-Side-Schalter ausschaltet, wenn ein Spannungsabfall an der Last detektiert wird.
Abstract:
Beschrieben sind Vorrichtungen und Verfahren zum Stromausgleich, Stromabtastung und Phasenausgleich, Versatzeliminierung, Digital-zu-Analog-Stromwandlung mit monotoner Ausgabe unter Nutzung von binärkodierten Eingaben (ohne einen Binär-zu-Thermometer-Decoder), Kompensator für einen Spannungsregulator (VR), etc. In einem Beispiel umfasst die Vorrichtung: mehrere Induktivitäten, die an einen Kondensator und eine Last koppeln, mehrere Brücken, wovon jede gekoppelt ist an eine entsprechende Induktivität von den mehreren Induktivitäten; und mehrere Stromsensoren, wovon jeder gekoppelt ist an eine Brücke zum Abtasten eines Stromes durch einen Transistor der Brücke.
