摘要： A heterogeneous processing system is described herein that provides a software hypervisor to autonomously control operating system thread scheduling across big and little cores without the operating system's awareness or involvement to improve energy efficiency or meet other processing goals. The system presents a finite set of virtualized compute cores to the operating system to which the system schedules threads for execution. Subsequently, the hypervisor intelligently controls the physical assignment and selection of which core(s) execute each thread to manage energy use or other processing requirements. By using a software hypervisor to abstract the underlying big and little computer architecture, the performance and power operating differences between the cores remain opaque to the operating system. The inherent indirection also decouples the release of hardware with new capabilities from the operating system release schedule.

摘要： A storage abstraction system is described herein that exposes storage from an operating system as a uniform storage device and abstracts from applications the selection of a particular storage location and different properties of storage devices. The application provides the data to store and some information about the application's goals for storing the data, and lets the operating system route the data to the right place based on the data's characteristics. The operating system may choose to store data anywhere from L2 cache to a cloud-based storage service and anything in between, based on information about the data's persistence requirements, expected usage, access frequency, security needs, and so forth. The system lets applications and users focus on expressing their goals and needs for the data, and lets the operating system manage the hardware.

摘要： A transactional file system developed to function with flash memory is described. The file system performs power-failure detection and ensures data integrity in the event of a power failure. In one described implementation, a power failure event can be detected by a file system, components of the file system, or individual modules in the form or computer-executable instructions and/or logic. Meta-information is stored at a location on a flash medium indicated by a write pointer if a computer device shuts-down according to a normal shutdown mode. During initialization of the computer, a check is performed whether the meta-information is present in the location on the flash medium indicated by the write pointer. If the meta-information is present, then a conclusion is made that the computer shutdown according to the normal shutdown mode.

摘要： One or more secondary data structures are maintained containing mappings of logical flash memory addresses to physical flash memory addresses. Each secondary data structure has a predetermined capacity of mappings. A master data structure is also maintained containing a pointer to each of the one or more secondary data structures. Additional secondary data structures are allocated as needed to provide capacity for additional mappings. One or more counters associated with each of the one or more secondary data structures, respectively, provides an indication of when each of the one or more secondary data structures reaches the predetermined capacity of mappings.

摘要： A flash driver tracks data stored in a flash memory device through the use of logical-to-physical sector mapping. The mapping is stored in a data structure and allows data to be written into the next free physical sector in the flash memory medium. Write operations complete quickly, because there is no need to perform an erase operation in order to write new data on to the flash memory medium. Data loss due to power interruption during a write operation is also minimized by the described implementations. The logical-to-physical sector mapping stored in data structure is backed-up on the flash memory medium. In the event there is a catastrophic power interruption, logical-to-physical sector mapping can easily be reestablished by scanning the backed-up mapping in the flash memory medium. The backed-up information can be stored in a spare portion of a NAND or NOR flash memory medium.
摘要翻译：闪存驱动器通过使用逻辑到物理扇区映射来跟踪存储在闪存设备中的数据。映射被存储在数据结构中，并允许将数据写入闪存介质中的下一个空闲物理扇区。写操作快速完成，因为不需要执行擦除操作，以便将新数据写入闪存介质。在写入操作期间由于电源中断引起的数据丢失也通过所描述的实现来最小化。存储在数据结构中的逻辑到物理扇区映射被备份在闪存介质上。在发生灾难性电源中断的情况下，可以通过扫描闪存介质中的备份映射来轻松重新建立逻辑到物理扇区映射。备份信息可以存储在NAND或NOR闪存介质的备用部分中。

摘要： A transactional file system developed to function with flash memory is described. The file system provides for efficient storage of file system meta-information, performs robust transaction logging, and performs other related features. In one described implementation, metadata is stored in-line with data. In another embodiment, a transaction log is maintained by storing transaction information associated with requests to perform file transactions. The transaction information is stored at arbitrary physical sector addresses on the flash medium. In still another embodiment, a transaction log is stored in a physical sector of a flash medium. The transaction log contains transaction information associated with performing a file request. Metadata is written into a spare area of the physical sector indicating that the physical sector contains transaction information.

摘要： A power context system is described herein that makes decisions related to device power usage based on factors such as location, load, available alternatives, cost of power, and cost of bandwidth. The system incorporates contextual knowledge about the situation in which a device is being used. Using the context of location, devices can make smarter decisions about deciding which processes to migrate to the cloud, load balancing between applications, and switching to power saving modes depending on how far the user is from a power source. As the cloud becomes more frequently used, load balancing by utilizing distributed data warehouses to move processes to different locations in the world depending on factors such as accessibility, locales, and cost of electricity are considerations for power management. Power management of mobile devices is becoming important as integration with the cloud yields expectations of devices being able to reliably access and persist data.
