摘要： Example driver circuits can utilize shared-charge recycling charge pump structures. In particular, an example shared-charge recycling process may be applied to a clock buffer and charge transfer cells of the charge pump in a driver circuit. An example recycling process may include recycling of shared charges between the capacitors/capacitances in the charge transfer cells. An example recycling process may use the charges in one or more capacitors to charge one or more other capacitors before the charges are wasted or otherwise discharged to ground. Such recycling may significantly reduce the power consumption of the charge pump while still providing a high output voltage level, according to an example embodiment of the invention.

摘要： A cluster server manages allocation of free blocks to cluster clients performing writes in a clustered file system. The cluster server manages free block allocation with a free block map and an in-flight block map. The free block map is a data structure or hardware structure with data that indicates blocks or extents of the clustered file system that can be allocated to a client for the client to write data. The in-flight block map is a data structure or hardware structure with data that indicates blocks that have been allocated to clients, but remain in-flight. A block remains in-flight until the clustered file system metadata has been updated to reflect a write performed to that block by a client. After a consistency snapshot of the metadata is published to the storage resources, the data at the block will be visible to other nodes of the cluster.

摘要： A method includes initiating committing to persistent storage of a current consistency snapshot of a plurality of data objects in a redirect-on-write file system. Each of the plurality of data objects has a first copy of at least two copies of the data having a first context of at least two contexts. The method includes receiving, during committing to storage of the current consistency snapshot, an update to a data object of the plurality of data objects. The method also includes responsive to receipt of the update to the data object, creating a second copy of data of the data object from the first copy. The second copy of the data has a second context of the at least two contexts. The method includes responsive to receipt of the update to the data object, updating, based on the update, the second copy of the data of the data object.

摘要： A method, data processing system, and computer program product for managing data. A processor unit copies a data structure within a hierarchy of data structures to form a copy of the data structure. The data structure belongs to a level within a plurality of levels in the hierarchy of data structures. The processor unit associates an identifier with the data structure within the hierarchy of data structures. The processor unit increments a portion of the identifier for the data structure in response to copying the data structure to form the copy of the data structure and associating the identifier with the data structure within the hierarchy of data structures. The portion of the identifier that is incremented is based on the level within the plurality of levels in which the data structure is located.

摘要： A method, apparatus, and computer instructions for managing data in a file system in a data processing system. A request to modify a data block in the file system is detected during file system recovery time. In response to detecting the request, metadata is written to describe the data block into a snapshot image. The data is copied for the data block in the file system to the snapshot image. The data block is modified in the file system after the data is copied into the snapshot image. The snapshot image may be used to return the file system to a state prior to modifying the data block in the file system.

摘要： Management of a file hierarchy for a clustered file system can be distributed across nodes of the cluster. A cluster file hierarchy is accessed to determine location of a file in response to a request to write to a file. A first node maintains the cluster file hierarchy. It is determined that management of a fileset object, which represents a fileset that includes the file, has been delegated to a second node based, at least in part, on said accessing the cluster file hierarchy. A node file hierarchy maintained by the second node is accessed responsive to determining the delegation. The cluster file hierarchy represents filesets of the clustered file system and the node hierarchy represents a subset of one or more of the filesets. Location of the file is determined based, at least in part, on said accessing the node file hierarchy.

摘要： A communication system includes a configurable transceiver that accommodates multi-band, multi-format signals by incorporating a duplex transceiver circuit, a simplex transceiver circuit and at least two switches. A first switch may be operated so as to configure the configurable transceiver to propagate duplex signals, such as for example, frequency division multiplexed (FDD) signals. The second switch may be operated so as to configure the simplex transceiver circuit to provide signal propagation of various types of signals in either a receive direction or a transmit direction. The various types of signals include time division multiplexed (TDD) signals.
