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 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： 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： 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 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： 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 storage placement system is described herein that uses an operating system's knowledge related to how data is being used on a computing device to more effectively communicate with and manage flash-based storage devices. Cold data that is not frequently used can be differentiated from hot data clusters and placed in worn areas, while hot data that is frequently used can be kept readily accessible. By clustering hot data together and cold data in separate sections, the system is better able to perform wear leveling and prolong the usefulness of the flash medium. Storage of data in the cloud or other storage can intelligently persist data in a location for a short time before coalescing data to write in a block. Thus, the system leverages the operating system's knowledge of how data has been and will be used to place data on flash-based storage devices in an efficient way.
摘要翻译：本文描述了一种存储放置系统，其使用操作系统与计算设备上如何使用数据相关的知识来更有效地与基于闪存的存储设备通信并管理基于闪存的存储设备。不经常使用的冷数据可以与热数据集群区分开，并置于磨损区域，而经常使用的热数据可以很容易地访问。通过将热数据集中在一起，并将冷数据分组在不同的部分，系统能够更好地执行磨损平衡并延长闪光介质的有用性。将数据存储在云端或其他存储器中可以将数据在数据写入块之前在一段时间内智能地保持在一个位置上的数据。因此，该系统利用操作系统了解数据如何以及将被用于以有效的方式将数据放在基于闪存的存储设备上。
