摘要： Embodiments of the invention intelligently associate processes with core processors in a multi-core processor. The core processors are asymmetrical in that the core processors support different features or provide different resources. The features or resources are published by the core processors or otherwise identified (e.g., via a query). Responsive to a request to execute an instruction associated with a thread, one of the core processors is selected based on the resource or feature supporting execution of the instruction. The thread is assigned to the selected core processor such that the selected core processor executes the instruction and subsequent instructions from the assigned thread. In some embodiments, the resource or feature is emulated until an activity limit is reached upon which the thread assignment occurs.

摘要： Embodiments provide a security infrastructure that may be configured to run on top of an existing operating system to control what resources can be accessed by an applications and what APIs an application can call. Security decisions are made by taking into account both the current thread's identity and the current thread's call chain context to enable minimal privilege by default. The current thread context is captured and a copy of it is created to be used to perform security checks asynchronously. Every thread in the system has an associated identity. To obtain access to a particular resource, all the callers on the current thread are analyzed to make sure that each caller and thread has access to that resource. Only when each caller and thread has access to that resource is the caller given access to that resource.
摘要翻译：实施例提供了可被配置为在现有操作系统之上运行以控制应用程序可以访问哪些资源以及应用程序可以调用哪些API的安全基础设施。通过考虑当前线程的身份和当前线程的调用链上下文来进行安全性决策，以在默认情况下实现最小权限。捕获当前线程上下文，并创建其副本以用于异步执行安全检查。系统中的每个线程都有一个关联的身份。为了获得对特定资源的访问，分析当前线程上的所有调用者，以确保每个调用者和线程都可以访问该资源。只有当每个调用者和线程都能访问该资源时，调用者才能访问该资源。

摘要： Scheduling of threads in a multi-core system running various legacy applications along with multi-core compatible applications is configured such that threads from older single thread applications are assigned fixed affinity. Threads from multi-thread/single core applications are scheduled such that one thread at a time is made available to the cores based on the thread priority preventing conflicts and increasing resource efficiency. Threads from multi-core compatible applications are handled regularly.

摘要： A method of managing memory of a computing device includes providing a first memory that can be allocated as cache memory or that can be used by a computing device component. A first memory segment can be allocated as cache memory in response to a cache miss. Cache size can be dynamically increased by allocating additional first memory segments as cache memory in response to subsequent cache misses. Cache memory size can be dynamically decreased by reallocating first memory cache segments for use by computing device components. The cache memory can be a cache for a second memory accessible to the computing device. The computing device can be a mobile device. The first memory can be an embedded memory and the second memory can comprise embedded, removable or external memory, or any combination thereof. The maximum size of the cache memory scales with the size of the first memory.

摘要： A method of acquiring software profile information of a target software application includes receiving a programmed interrupt while executing an application in a computer system, servicing the interrupt such that call stack information is acquired and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. Some or all of the call stack information may be recorded. The statistical information includes statistics concerning the number of samples wherein a series of functions calls are included in the call stack information and the number of samples wherein a set of function calls are at the top of the call stack information.

摘要： Scheduling of threads in a multi-core system is performed using per-processor queues for each core to hold threads with fixed affinity for each core. Cores are configured to pick the highest priority thread among the global run queue, which holds threads without affinity, and their respective per-processor queue. To select between two threads with same priority on both queues, the threads are assigned sequence numbers based on their time of arrival. The sequence numbers may be weighted for either queue to prioritize one over the other.

摘要： Various implementations of the described subject associate a plurality of threads that are sorted based on thread priority with a run queue in a deterministic amount of time. The run queue includes a first plurality of threads, which are sorted based on thread priority. The second plurality of threads is associated with the run queue in a bounded, or deterministic amount of time that is independent of the number of threads in the associated second plurality. Thus, the various implementations of the described subject matter allow an operating system to schedule other threads for execution within deterministic/predetermined time parameters.

摘要： Various implementations of the described subject matter provide for the management of a multi-dimensional sleep queue, such that a group of threads with a same wake-up time are removed from the multi-dimensional sleep queue in a deterministic amount of time that is independent of the number of threads in the removed group. This is significant because it allows an operating system to schedule other threads for execution within deterministic/predetermined time parameters. Moreover, the described subject matter also provides for inserting new threads into the multi-dimensional sleep queue in a manner that allows other processes to execute during the thread insertion process.
