An apparatus, system, and method are disclosed for caching data on a solid-state storage device. The solid-state storage device maintains metadata pertaining to cache operations performed on the solid-state storage device, as well as storage operations of the solid-state storage device. The metadata indicates what data in the cache is valid, as well as information about what data in the nonvolatile cache has been stored in a backing store. A backup engine works through units in the nonvolatile cache device and backs up the valid data to the backing store. During grooming operations, the groomer determines whether the data is valid and whether the data is discardable. Data that is both valid and discardable may be removed during the grooming operation. The groomer may also determine whether the data is cold in determining whether to remove the data from the cache device. The cache device may present to clients a logical space that is the same size as the backing store. The cache device may be transparent to the clients.

A method and apparatus for synchronizing a client-side information store with a server-side database in a client / server architecture are disclosed.

For a text message received by a mobile terminal, some or all of the message is converted to voice-based content, depending upon the user's preference or upon the capability of the wireless device's display. When the display of the mobile terminal is too small to accommodate a large text-based message, a software module converts the text-based content to voice-based content. The voice-based content is then output to a speaker in the wireless device. For received messages of more than one type of content, only the portions of the message that are within the capabilities of the receiver are outputted, or converted to another type of content if possible.

A binary theme file format provides optimized access to retrieve graphical component theme property data. The binary format includes data structures storing a set of defined visual characteristics for graphical component classes, parts, and states. The data structure includes a hierarchy of theme data. A theme manager quickly retrieves theme property data by indexing into the binary file with a unique theme handle. The theme manager accesses state, part, class, and global property sections to retrieve theme data. Jump tables and jump-to-parent references allow for quickly traversing property data sections. Packed data sections have packed objects having the necessary property data for frequently used graphical components. A custom image region data section provides border data for nontransparent image borders. A sampled colors section facilitates rendering of images with solid sections. The binary file format can be constructed using a text theme file and is loaded into shared process memory.

A database management and indexing technique provides coherent access to and update of dynamic configuration information stored in a database associated with a multiprocessing environment of an aggregation router. The multiprocessing environment comprises a forwarding engine configured as a computing matrix of processors that operate on packets in a parallel as well as a pipeline fashion. A unique handle, i.e., a virtual common coherency index (VCCI) value, is associated with an interface regardless of whether it is a virtual or a physical interface. When a packet enters the computing matrix, it is classified and assigned a VCCI value based upon the interface over which it is received at or transmitted from the router. The assigned VCCI value is then passed along with the packet to each feature that processes the packet.
