Network communications, Web-based services and customized services using the Web-based services may be provided to drivers and users via the automobile head unit in the vehicle and via their mobile device. The automobile head unit in the vehicle and the mobile device are communicatively linked via a short range wireless connection. Also, these devices may communicate over a network such as a cellular network to a service provider that provides entertainment and informational services to the mobile device and the head unit of the vehicle. The user's profile and preferences are able to follow the user to various locations and into vehicles because this information is stored at a server accessible by the user's mobile device, and in some embodiments, also the head unit. The mobile device may provide services to the head unit if it does not have wider network connectivity over the short range wireless connection.

In one aspect, the present disclosure describes a process for maintaining file allocation tables (FATs) for a volume of storage medium. The process includes triggering, by a write operation, modification of data in an existing sector of a data file by writing of data to a new sector of the storage medium. The process also includes writing revised used/unused sector information into one FAT and setting a variable indicative of a number of FATs (NOF) to a first value. The process additionally includes copying the one FAT to another FAT and re-setting the variable to a second value.

Transaction-safe FAT files system

Methods and systems for operating computing devices are described. In one embodiment, a small amount of static RAM (SRAM) is incorporated into an automotive computing device. The SRAM is battery-backed to provide a non-volatile memory space in which critical data, e.g. the object store, can be maintained in the event of a power loss.

Software management

Methods and systems for operating automotive computing devices are described. In one embodiment, a small amount of static RAM (SRAM) is incorporated into an automotive computing device. The SRAM is battery-backed to provide a non-volatile memory space in which critical data, e.g. the object store, can be maintained in the event of a power loss. Circuitry is provided to ensure that the SRAM receives back up power from the battery at appropriate times. Software manages the SRAM and the other storage assembly components and makes use of virtual paging or virtual addressing techniques to keep track of where various pages, including object store pages, are stored in the system. The software knows where all of the object store pages are located so that in the event of a power loss, the page locations are known and hence the pages can be used when power is restored. The SRAM is advantageously used to maintain so-called 'dirty pages' or pages that have been written to so that these pages are not lost in the event of a power interruption. Additionally, the software can also provide an orderly means by which pages in the SRAM can be written out to flash memory thereby avoiding unnecessary flash write operations which, in turn, increases the lifetime of the flash memory.

Transaction-safe FAT file system

Methods and systems for operating automotive computing devices are described. In one embodiment, multiple object store pages are maintained in device SRAM that is configured to be battery backed in an event of a power loss. One or more object store pages are periodically flushed to device non-volatile memory to make room for additional object store pages. The frequency of object store page writes is tracked, and object store pages that are least frequently written to are flushed before object store pages that are more frequently written to. In addition, in the event of a power loss, the SRAM is battery backed.

Automotive computing devices with emergency power shut down capabilities

Methods and systems for operating automotive computing devices are described. In one embodiment, an automotive computing device is provided having a processor, volatile memory, non-volatile memory, and SRAM. An object store is provided for the computing device in the non-volatile memory. One or more pages from the object store are maintained in the SRAM.

A method for facilitating fast start-up/shut-down of a computing device having a processor, volatile memory, non-volatile memory, and SRAM is described. In one embodiment, an object store for the computing device is provided in the non-volatile memory. A fast lossless shut-down of the computing device may be accomplished by periodically writing data from the object store to a non-volatile medium during operation of the computing device.

Automotive computing devices are described. In one embodiment, the system comprises means for maintaining a translation look-aside buffer that contains entries for recently translated virtual page addresses; means for maintaining a page table in device memory that contains a map for every valid virtual page address; and means for maintaining an object store page table in device SRAM that contains information associated with locations for every object store page.

Automotive computing systems

Programmable automotive computing devices and methods are described. In but one embodiment, the automotive computing device is programmed to copy an object store into device flash memory and to create an object store page table in device SRAM that is configured to track the locations of all of the object store pages in the device.
