Apparatus and methods to filter memory record updates. A microprocessor can include a memory record update filter. The memory record update filter can include a table memory populated by a plurality of data entries. Each data entry can include a data tag field to store a data tag, a data field to store a data value, and a filter field to store a filter value. A first comparator can be in communication with the data tag field of the table memory and a data accessing information input to perform a...

A method for allowing a software vendor to notify a user of a software update is disclosed. At the time of installing an application, the user is prompted to subscribe to a software update channel. A shortcut (.lnk file) that the application installs is created with special information that identifies the application by a unique name. The channel is updated periodically based on the schedule suggested by the channel. When a new update is detected, the software channel delivers the software updat...

To improve the efficiency for an update process in a software processing device with a plurality of memory partitions (4,14) it is proposed to continue the execution of old software on original data stored in a first memory partition (4). In case the same state for data of old and new software is achieved (S4) an instant switch of services to the new software as far as the same state is achieved (S5) takes place. This processing is repeated (S6) until no data to be transferred remains (S6) in th...

A fuel-injection system for an internal combustion engine that operates in a stratified mode of fuel injection during a first engine speed range and a homogeneous mode of fuel injection during a second engine speed greater than the first range. A changeover speed is determined for a particular engine and, upon speed (or load) increasing to the point of changeover from the stratified mode, the engine speed update point changes from a first or "standard" update point to a second predetermined "pro...

In a microprocessor system, a program counter circuit generates a program counter value that represents a retrieved instruction and that includes a more significant portion, a less significant portion, and a carry signal for use in determining a next program counter value. An execute program counter circuit generates an execute program counter value from the less significant program counter value and from the carry signal. The execute program counter value represents a program counter value of a...

A method of updating firmware between an imaging device and a host system is disclosed. The host system detects that the firmware on the imaging device is incompatible with a configuration of the host system. In response to detecting the incompatibility, an updated firmware image is transferred from the host system to the imaging device.

A method and apparatus for utilizing satellite update information are disclosed. In the preferred embodiment satellite update information, comprising satellite position, polarity, name, and abbreviation, are accumulated at a first location and transmitted via satellite to at least one of a plurality of satellite receivers. The satellite receiver is operable to receive and automatically utilize the satellite update information such that the end user of the satellite receiver in unaware of the aut...

A search data update system includes a navigation apparatus in which search data are used and a data provider center that provides the navigation apparatus with update data to be used to update the search data. The update data provided by the data provider center only include new search tree data and update entity data. The new search tree data assume a structure that enables specification of the update entity data and specification of the entity data in the original search data except for the e...

Updating a file which is currently open is accomplished by allowing current users to continue accessing the original file while redirecting new users to an updated version. When user activity permits, the updated version is substituted for the original file. An auxiliary program detects when a server application attempts to access an out-of-date file version and redirects the access call to the up-to-date file version. When no users are accessing the out-of-date file version, the up-to-date vers...
