Abstract:
A method, apparatus, and system to enable a partial refresh scheme for DRAM which includes specifying at least a refresh start value, or a refresh start value and a refresh end value, to reduce the number of rows that must be refreshed during a refresh cycle, thus reducing the amount of power consumed during refresh.
Abstract:
In one embodiment a memory controller is provided. The memory controller comprises a predictive logic circuit to predict an increase in a current operating temperature of a memory device coupled to the memory controller, based on memory cycles to be issued to the memory device; and a temperature control circuit to perform a temperature control operation wherein if the sum of the current operating temperature and the predicted increase in temperature is greater than a threshold temperature associated with the memory device, then the number of memory cycles issued to the memory device is reduced.
Abstract:
An in-line trigger is a modular, compiled, template trigger, which defines a series of actions to be performed when an operation is applied to a body of data. The series of actions to be performed when an in-line trigger fires are compiled into machine language instructions that receive three kinds of parameters: trigger-type specific parameters, operational metadata, and operational data. Trigger-type specific parameters are loaded into a section of run-time memory once for multiple firings of the same trigger. Operational metadata and operational data are loaded each time the trigger fires.
Abstract:
A method and system are provided for duplicating at a destination site changes made to data at a source site. According to the method a plurality of streams are established between the source site and the destination site. The plurality of streams are used in parallel to propagate changes made at the source site to the destination site. A record of transactions that made changes that need to be propagated from the source site to the destination site is maintained at the source site. Before propagating changes made by a transaction to the destination site on a stream of the plurality of streams, the record of transactions is inspected to identify a set of transactions whose changes are not known to have been made permanent at the destination site. It is then determined whether the transaction could possibly depend on any transaction in the set of transactions. If the transaction could not possibly depend on any transaction in the set of transactions, then the changes made by the transaction are propagated to the destination site using one of the plurality of streams.
Abstract:
The present invention provides the ability to replicate modifications made at a local site to multiple remote sites in a peer-to-peer environment. Information regarding these replicated modifications (e.g., insert, delete, or update) are contained in a set of replication tables. Thus, modifications can be duplicated at other sites immediately after the original modification, or deferred until the remote site is available. The replication tables of the present invention include a transactions table, transaction nodes table, calls table, call nodes table, and an exceptions table. The present invention further provides a logic-oriented procedure-level replication. Procedure-level replication modifies a remote site based on the logical operations used to modify the data at the originating site. Procedure-level replication provides the ability to identify conflicting updates as well. Information concerning conflicts identified by the present invention can be retained in the replication tables. The information contained in the replication tables can be used immediately, or subsequently, to address any conflicts detected by the present invention. The present invention provides the ability to rollback any modifications made once a conflict is identified. Further, the present invention provides the ability to address these conflicts within an application program. The present invention provides a row-oriented replication. A trigger associated with a table queues deferred remote procedures. The remote procedures use the old and new values from the original modification to replicate the modification at remote sites and detect conflicting updates.
Abstract:
Aluminum-molybdenum composite sheet is produced by assembling aluminum and molybdenum sheets to form a billet, rolling the assembled billet in a protective atmosphere at a temperature of about 100.degree. to 400.degree. C. to affect a reduction in thickness of at least about 40% to provide a bonded billet. The billet can be further reduced by hot and/or cold rolling.
Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, including a method comprising: receiving a content item request from a resource, the resource associated with a resource sponsor; verifying the content item request including filtering out spam requests and determining if the content item request is valid; for any invalid requests, providing a content item in response to the content item request that is in conformance with an existing definition provided by the resource sponsor; and presenting information related to invalid requests to the resource sponsor in a user interface, the user interface including tools for enabling the resource sponsor to automatically accept and validate a content item request so that subsequent requests of the same type are validated upon receipt.
Abstract:
A set of tools and other mechanisms automatically enforce software development change policies by providing a way to map physical source control system codelines to projects and by providing a way to maintain current project and codeline state information. The set of tools and other mechanisms also provide ways to define change management rules and policies, as well as, ways to evaluate and allow or deny each proposed change against the defined change policy.
Abstract:
A thermal management system is described which may be implemented on a semiconductor die. The system may include a thermal sensor thermally coupled to the die to sense the temperature of the die and generate an output representing the sensed temperature, and an adjustable compensation circuit coupled to the thermal sensor to compensate the thermal sensor output. The adjustable compensation circuit may be applied to the thermal sensor or to a threshold.
