Abstract: The creation, maintenance, and accessing of page tables is done by a virtual machine monitor running on a computing system rather than the guest operating systems. This allows page table walks to be completed in fewer memory accesses when compared to the guest operating system's maintenance of the page tables. In addition, the virtual machine monitor may utilize additional resources to offload page table access and maintenance functions from the CPU to another device, such as a page table management device or page table management node. Offloading some or all page table access and maintenance functions to a specialized device or node enables the CPU to perform other tasks during page table walks and/or other page table maintenance functions.

Abstract: Methods and systems are described for generating a vehicle-to-vehicle traffic alert and updating a vehicle-usage profile. Various aspects include detecting, via one or more processors associated with a first vehicle, that an abnormal traffic condition exists in an operating environment of the first vehicle. An electronic message is generated and transmitted wirelessly, via a vehicle-mounted transceiver associated with the first vehicle, to alert a nearby vehicle of the abnormal traffic condition and to allow the nearby vehicle to avoid the abnormal traffic condition. The first vehicle receives telematics data regarding operation of the nearby vehicle after the nearby vehicle received the electronic message, and transmits the telematics data to a remote server for updating a vehicle-usage profile associated with the nearby vehicle.

Abstract: A memory module supports multiple memory channel modes, each including a double-date-rate (DDR) data channel supported by an independent command-and-address (CA) channel. In a two-channel mode, the memory module supports two DDR data channels using two respective DDR CA channels. Each CA channel includes a corresponding set of CA links. In a four-channel mode, the memory module supports two pairs of DDR data channels, each pair supported by a pair of independent CA channels. Memory commands issued in the four-channel mode are time interleaved to share one of the sets of CA links.

Abstract: A dynamic random access memory (DRAM) device includes functions configured to aid with operating the DRAM device as part of data caching functions. The DRAM is configured to respond to at least two types of commands. A first type of command (cache data access command) seeks to access a cache line of data, if present in the DRAM cache. A second type of command (cache probe command) seeks to determine whether a cache line of data is present, but is not requesting the data be returned in response. In response to these types of access commands, the DRAM device is configured to receive cache tag query values and to compare stored cache tag values with the cache tag query values. A hit/miss (HM) interface/bus may indicate the result of the cache tag compare and stored cache line status bits to a controller.

In some aspects, the vehicle may be rented, and the intended vehicle usage is measured in distance or duration of vehicle operation. Insurance discounts may be provided to risk averse vehicle owners based upon low risk levels.
