Abstract: A circuit includes circuit portions operating from separate power supplies which are switched sequentially. An output of a first portion powered by a power supply (A) is provided as an input to a second portion powered by another power supply (B). Power supply (A) is switched-ON a delay interval later than power supply (B). In an embodiment, the first portion also receives a control input which enables or disables response of the first portion to changes in its inputs. An active circuit is connected between the control terminal and a constant reference potential node of the circuit, and has one transistor of a current-mirror pair connected across supplies (A) and (B). The active circuit connects the control terminal to the constant reference potential node in the delay interval, but is an open circuit otherwise. Power dissipation in the circuit is thereby reduced.

Abstract: Determining efficiently whether it is necessary to re-inventory a storage media library, such as a tape library, is disclosed. It is determined whether a first number computed based at least in part on at least a portion of a new inventory data is the same as a second number computed based at least in part on a corresponding stored inventory data. An update of the stored inventory data is initiated if it is determined that the first number is not the same as the second number.

Abstract: A power management (PM) system architecture for a controlled SoC detects availability of power supply for signal-driving at a given node inside a chip, and uses a timer, a discharge mechanism with trigger for starting/stopping a discharge process, and a comparator for monitoring a measured voltage of an intended node during the discharge process. Enabling the discharge mechanism for a known time period helps detection. Power supply can be internally generated in the chip or from a source on board. The architecture detects if the node is driven or floating, an undriven floating node causing a dip in the measured voltage. The measured voltage does not have a dip when the node is driven. The architecture is also configured so that when there is a required on-board external power supply, an internal power supply is disabled to avoid a race-condition. The architecture obviates a dedicated IO pin for mode-indication.

Abstract: The present invention is a system and method for extending the functionality of tape device tapemarks. When data is backed up to tape, the tape controller may mark the tape with a tapemark to organize portions of the tape. Present tape storage devices are limited to a single type of tapemark; therefore current recovery requests require knowledge of the tapemark location. The present invention allows for unique types of tapemarks. By allowing the tape device, tape controller and/or backup and recovery software to recognize unique tapemarks, data organized by unique tapemarks can be recovered without referencing tapemark location, thereby optimizing recovery. Unique tapemarks may be encrypted such that data recovery is only completed upon verification of the requester.

The analog circuit receives an in-band range of signals. A value of N is configured to shift the interference signals outside the in-band range of signals.

A switched bandgap reference includes bandgap reference circuit coupled to a storage capacitor through a switch. A logic having a set of control signals controls the switch and the bandgap reference circuit such that during a retention mode the bandgap reference circuit and the switch are active for a first time interval in response to the set of control signals to recharge the storage capacitor and then inactive for a second time interval in response to the set of control signals that decouples the bandgap reference circuit from the storage capacitor. The charge stored in the storage capacitor is used to generate a reference voltage.
