摘要:
A method and system for automatically identifying configuration cell addresses in a schematic hierarchy is disclosed. In one embodiment of the present invention, a memory cell (e.g., a configuration bit) is identified in a schematic hierarchy. Next, this embodiment determines an address for the memory cell. Then, this embodiment determines a unique name for the memory cell. The name is comprised of a hierarchical logical name and a schematic path name. By traversing the schematic and using logical names, all addresses of configuration bits of a circuit design may be automatically determined. The process is repeated for each memory cell in the schematic. This embodiment stores the unique name of the configuration bit and the address of the configuration bit in a data structure.

A method and system for automatically building a bit order data structure of configuration bits for a programmable logic device. One embodiment of the present invention first identifies a plurality of memory cells in a hierarchical schematic representation of the programmable device. Next, this embodiment determines a plurality of addresses corresponding to the plurality of memory cells. This embodiment next determines a plurality of logical names for the plurality of memory cells. Then, based on an order in which the plurality of addresses are to be loaded into the programmable logic device, this embodiment orders the plurality of logical names for the plurality of memory cells. Another embodiment first accesses a database comprising a plurality of logical names corresponding to a plurality of addresses. Then, this embodiment accesses a database specifying an order in which the plurality of addresses are to be loaded into the programmable logic device. Next, this embodiment orders the plurality of logical names based on the order specified in the database from the previous step.

The present invention provides a dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprising: a housing comprising a body portion and a removable mouthpiece, the body portion containing a dose counting mechanism and a sleeve; the body portion comprising an aperture through which said pressurised dispensing container can pass to be received in the sleeve but through which the sleeve is unable to pass such that the sleeve is retained within the body portion; the sleeve being located in the body portion such that an upper end of said pressurised dispensing container when received in the sleeve is accessible to allow actuation of said pressurised dispensing container; the apparatus comprising means for retaining said pressurised dispensing container in the body portion.
摘要:
Managing a log-full condition of a transaction log in a transaction processing system, where the transaction log has a plurality of log records each associated with a particular transaction. When a log-full condition is detected, the active transaction having the oldest log entry of all active transactions is identified and logging for all transactions except for the identified transaction is temporarily suspended. A dynamic transaction backout of the identified transaction is initiated, with the writing of a backout record for the identified transaction to the log being delayed. Confirmation that the backout has completed is awaited before trimming the log. Then the delayed backout record for the identified transaction is written to the log, and normal logging is resumed.
摘要:
Engine control is provided for an engine having a crankshaft and at least one camshaft with variable valve timing in a rotation transmitting train between the crankshaft and the camshaft. A first value indicative of a cam angle at a home position at a first time is compared to a second value indicative of a cam angle at the home position at a second, earlier, time. Where a deviation in the compared values is detected that does not exceed a threshold value, the first value is stored for use in a subsequent comparison. Where a deviation in the compared values is detected that does exceed a threshold value, a failure condition is detected and the MIL light is illuminated. In this case, the value stored for comparison is not updated.

Avoiding failure repetition in data processing includes storing a sequence of circumstances leading up to a previous failure, monitoring circumstances in a current process, matching a sequence of circumstances in the current process to a stored sequence of circumstances, and applying rules to determine if the current process should proceed.
摘要:
A method and transaction processing system for managing transaction processing tasks are provided. The transaction processing system comprises a transaction log, a log management policy, a log manager and a dispatcher. The method comprises maintaining a transaction log of recoverable changes made by transaction processing tasks and storing a log management policy including at least one log threshold. Usage of the log by transaction processing tasks is then monitored to determine when a log threshold is reached. When a log threshold is reached the active task having the oldest log entry of all active tasks is identified and its dispatching priority is increased. This increases the likelihood that the identified task will be dispatched, and should mean that the task will more quickly reach normal completion.
