摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.

摘要： An application programming interface (API) may receive high level file commands and implement those commands using the storage mechanism on a smart card. The smart card may have a processor and storage mechanism and may communicate to a host device using a packet based communication protocol, such as ADPU. The API may translate the high level file commands into one or more ADPU commands, communicate with the smart card, receive APDU responses, and translate the responses into high level file commands. A high level file command may allow access to a file using long file names, a hierarchical directory structure, and may allow creating, writing, reading, and deleting a file. Some embodiments may have more complex functions for navigating and manipulating a hierarchical directory structure, as well as defining metadata including access privileges and file types to individual files.

摘要翻译： 应用编程接口（API）可以接收高级文件命令，并使用智能卡上的存储机制来实现这些命令。 智能卡可以具有处理器和存储机制，并且可以使用诸如ADPU的基于分组的通信协议来与主机设备通信。 API可以将高级别文件命令转换成一个或多个ADPU命令，与智能卡通信，接收APDU响应，并将响应转换成高级文件命令。 高级文件命令可以允许使用长文件名，分层目录结构访问文件，并且可以允许创建，写入，读取和删除文件。 一些实施例可以具有用于导航和操纵分层目录结构的更复杂的功能，以及将包括访问特权和文件类型的元数据定义到单个文件。

摘要： The present invention provides providing predictable scheduling of programs using repeating precomputed schedules on discretely scheduled and/or multiprocessor operating systems. In one embodiment, a scheduler accesses an activity scheduling graph. The activity scheduling graph is comprised of nodes each representing a recurring execution interval, and has one root, one or more leaves, and at least one path from the root to each leaf. Each node is on at least one path from the root to a leaf, and the number of times the execution interval represented by each node occurs during the traversal of the graph is equal to the number of paths from the root to a leaf that the node is on. Each node has associated with it an execution interval length, and is adapted to being dedicated to executing the threads of a single activity. There may be one scheduling graph for each processor, or a scheduling graph may traverse multiple processors. Start and end times for reservations and constraints are adjusted to compensate for the granularity of the clock of the system. Furthermore, the scheduler may use an existing priority-based scheduler in order to cause scheduling decisions it has made to be acted upon.

摘要： The present invention provides predictable scheduling of programs using a repeating precomputed schedule. In a preferred embodiment, a scheduler accesses an activity scheduling graph. The activity scheduling graph is comprised of nodes each representing a recurring execution interval, and has one root, one or more leaves, and at least one path from the root to each leaf. Each node is on at least one path from the root to a leaf, and the number of times the execution interval represented by each node occurs during the traversal of the graph is equal to the number of paths from the root to a leaf that the node is on. Each node has associated with it an execution interval length, and is adapted to being dedicated to executing the threads of a single activity. The scheduler first selects a current node within the accessed scheduling graph. When the processor becomes available to execute threads, the scheduler advances from the current node to a new current node in accordance with a root-to-leaf traversal of the scheduling graph. After advancing to the new current node, the scheduler executes one or more threads of the activity to which the new current node is dedicated for the execution interval length associated with the new current node. In a further preferred embodiment, the scheduler allocates specific iterations through specific nodes to satisfy the constraints submitted by threads.
