摘要： A set of Application Program Interfaces (APIs) for a resource-limited environment are disclosed. The APIs provide a mechanism for a computer application to interface with various components and modules of an operating system for a resource-limited environment. The APIs further provide a mechanism to interface with input/output devices commonly found in embedded systems running in a resource-limited environment.

摘要： Systems and methods for dynamically variable idle time thread scheduling are described. In one aspect, threads are scheduled according to a predetermined periodic rate. If there are no threads to execute, one or more hardware elements and program modules are deactivated to an idle state for a dynamic variable amount of time. The dynamic variable amount of time is independent of the predetermined periodic rate at which threads are scheduled. The dynamic variable amount of time is also independent of key press events, and any event associated with release of a resource. Instead, the dynamic variable amount of time is based on a sleep state of a set of threads in a sleep queue.

摘要： The subject matter provides dynamically variable idle time thread scheduling in a device with a high system tick rate. A device based on the subject matter includes an operating system, a set of application program modules, and one or more hardware elements. A thread scheduling mechanism in the operating system schedules threads at a periodic rate. Upon determining that there are no threads to execute, at least a subset of components are deactivated for a dynamic variable amount of time before they are is re-activated. The at least one subset of components are selected from the hardware elements, one or more program modules comprising the operating system, and the like. The dynamic variable amount of time is independent of the periodic rate and based on a sleep state of a set of threads in a sleep queue.

摘要： Systems and methods for synchronizing a device and for ensuring that updates to the device occurring during synchronization are not re-synchronized to the synchronization partner. Generation identifiers (GIDs), which are updated each time a synchronization occurs, are assigned to objects in a store. When synchronization occurs, a sync client uses state information, which is used to indicate which generations have been synchronized, to determine which objects have changed since the last synchronization. The state information includes reserved write GIDs that are only used by a particular sync client that performs writes during a synchronization. Objects having a GID that matches a write GID are not synchronized because they were written by the sync client during the previous synchronization.

摘要： Described herein is a method of controlling memory usage in a computer system having limited physical memory, wherein one or more application programs execute in conjunction with an operating system. At a first memory usage threshold, the operating system requests at least one of the application programs to limit its use of memory. At a second memory usage threshold that is more critical than the first memory usage threshold, the operating system requests at least one of the application programs to close itself. At a third memory usage threshold that is more critical than the first and second memory usage thresholds, the operating system terminates at least one of the application programs without allowing its further execution.

摘要： A method and system are described for updating software modules bundled in a read-only device of a computer. According to the invention, when a software module is to be executed from the read-only device, the operating system identifies any other software modules stored within the read-only device on which the application depends. After identifying all of the dependencies, the operating determines whether a newer version of any of the identified software modules has been installed on the computer. The operating system copies into a read/write device a portion of the software module that references the old software modules. After copying the portion, the operating system modifies all references to point to the new versions of the software module. The invention allows software modules to be primarily executed from the read-only device with only a small updated portion being executed from a read/write device.

摘要： A system implementing an execute-in-place (XIP) architecture is presented comprising a plurality of XIP regions. To facilitate execute-in-place functionality across the multiple XIP regions, a virtual address table (VAT) is generated to store pointers to the objects stored in the non-volatile memory hosting the multiple XIP regions.

摘要： The invention includes a method of making a call from one process to another. The method includes executing a jump instruction from a first process, while specifying an invalid destination address such as an odd virtual memory address. The invalid address causes a memory fault, which in turn results in the invocation of a memory fault handler. The memory fault handler is configured to recognize certain specified invalid addresses, and to call different system functions depending on the particular values of the addresses. The thread of the calling process is used to execute both the fault handler and the called system functions.
