摘要： A mechanism is provided for automatic use of large pages. An operating system loader performs aggressive contiguous allocation followed by demand paging of small pages into a best-effort contiguous and naturally aligned physical address range sized for a large page. The operating system detects when the large page is fully populated and switches the mapping to use large pages. If the operating system runs low on memory, the operating system can free portions and degrade gracefully.

摘要： A method and processor architecture for achieving a high level of concurrency and latency hiding in an “infinite-thread processor architecture” with a limited number of hardware threads is disclosed. A preferred embodiment defines “fork” and “join” instructions for spawning new context-switched threads. Context switching is used to hide the latency of both memory-access operations (i.e., loads and stores) and arithmetic/logical operations. When an operation executing in a thread incurs a latency having the potential to delay the instruction pipeline, the latency is hidden by performing a context switch to a different thread. When the result of the operation becomes available, a context switch back to that thread is performed to allow the thread to continue.

摘要： An extended register processor includes a register file having a legacy register set and an extended register set. The extended register set includes a plurality of extended registers accessible only to extended register instructions. The processor maps extended register references to physical extended registers at run time. The processor includes a configurable extended register mapping unit to support this functionality. The mapping unit is accessible to an instruction decoder, which detects extended register references and forwards them to the mapping unit. The mapping unit returns a physical extended register corresponding to the extended register reference in the instruction. The mapping unit is configurable so that, for example, the mapping is specific to a code block. An extended register allocation instruction causes the processor to allocate a portion of the extended register set to the code block in which the declaration is located and to configure the mapping unit to reflect the allocation.

摘要： A method for managing data access in a mobile device is provided in the illustrative embodiments. Using a data manager executing in the mobile device, a data item is configured in a data model. A value parameter of the data item is populated with data and a status parameter of the data item is populated with a status indication. A subscription to the data item is received from a mobile application executing in the mobile device. In response to the subscription, the data and the status of the data item are sent to the mobile application.

摘要： The page tables in existing art are modified to allow virtual address resolution by mapping to multiple overlapping entries, and resolving a physical address from the most specific entry. This enables more efficient use of system resources by allowing smaller frames to shadow larger frames. A page table is selected. When a virtual address in a request corresponds to an entry in the page table, which identifies a next page table associated with the large frame, a determination is made that the virtual address corresponds to an entry in the next page table, the entry in the next page table referencing a small frame overlay for the large frame. The virtual address is mapped to a physical address in the small frame overlay using data of the entry in the next page table. The physical address in a process-specific view of the large frame is returned.

摘要： A method for fast remote communication and computation between processors is provided in the illustrative embodiments. A direct core to core communication unit (DCC) is configured to operate with a first processor, the first processor being a remote processor. A memory associated with the DCC receives a set of bytes, the set of bytes being sent from a second processor. An operation specified in the set of bytes is executed at the remote processor such that the operation is invoked without causing a software thread to execute.

摘要： Expert System supported interactive product selection and recommendation. The invention assists an agent to interact with a customer and to provide selection and recommendation of available products and/or services that offer a workable solution for the customer. The invention allows for the use of agents of varying skill levels, including relatively low skill level, without suffering deleterious performance. From certain perspectives, an expert system employed using various aspects of the invention allows the agent to provide real time interaction with a customer and to provide a real time recommended solution to that customer. Many traditional approaches dealing in complex industries require that agent's have a high degree of skill and expertise. The invention allows even a novice agent to service a customer's needs without requiring a high skill level or up-front training that is often at the expense of the provider seeking to market its products and/or services.
