摘要： In the various aspects, virtualization techniques may be used to reduce the amount of power consumed by execution of applications by power-optimizing the code prior to execution. A dynamic binary translator operating at the machine layer may use a power consumption model to identify code segments that can benefit from optimization and to perform an instruction-sequence to instruction-sequence translation of object code to generate power-optimized object code. Execution hardware may be instrumented with additional circuitry to measure the power consumption characteristics of executing code. The power consumption models may be updated and object code may be regenerated based on the measured the power consumption characteristics of previously executed code. In an aspect, power optimization may be accomplished when the computing device is connected to a battery charger.
摘要翻译： 在各个方面，虚拟化技术可以用于通过在执行之前对代码进行优化来减少执行应用所消耗的功率量。 在机器层上操作的动态二进制翻译器可以使用功耗模型来识别可以从优化中受益的代码段，并且执行指令序列到目标代码的指令序列转换以产生功率优化的目标代码。 执行硬件可以附加附加电路来测量执行代码的功耗特性。 可以基于测量的先前执行的代码的功耗特性来更新功耗模型并且可以重新生成目标代码。 在一个方面，当计算设备连接到电池充电器时，可以实现功率优化。

摘要： The aspects enable a processor to concurrently execute markup language code (e.g., HTML) having embedded scripting language code (e.g., JAVASCRIPT®) during a page load operation by a browser. A markup language parser parses markup language code until embedded scripting language code is encountered. The segment of embedded scripting language code is extracted for execution by a scripting language engine which proceeds concurrently with speculative parsing of the markup language code. Markup language code generated by execution of scripting language code is evaluated to determine if it is well formed, and a partial rollback of the markup language parse and re-parsing of portions of the markup language code is accomplished if not. Concurrent parsing of markup language code and execution of scripting language code, with partial roll back of the parsing process when necessary, continues until all markup language code has been parsed and all scripting language code has been executed.

摘要： One embodiment of the present invention provides a system that accesses memory locations in an object-addressed memory system. During a memory access in the object-addressed memory system, the system receives an object identifier and an address. The system then uses the object identifier to identify a paged memory object associated with the memory access. Next, the system uses the address and a page table associated with the paged memory object to identify a memory page associated with the memory access. After determining the memory page, the system uses the address to access a memory location in the memory page.

摘要： A virtual configuration system, comprising a virtualization engine and a configuration engine, for the dynamic instantiation of configuration files is disclosed. A mechanism is disclosed that allows for transactional updates to a repository of configuration settings comprising multiple files. Configuration entries are stored in a first memory location and a copy of the entries is stored in a second memory location. A virtual configuration file that includes a virtual configuration for each entry is created and used to provide the operating system with path and location information regarding the configuration entries. Simultaneously and during run-time of the computer, the configuration entries stored in the second memory location can be modified. Once the modifications are complete, a second virtual configuration file is created referencing the configuration entries stored at the second memory location. The first virtual configuration file is thereafter atomically replaced by the second virtual configuration file.

摘要： One embodiment of the present invention provides a system that provides precise exception semantics for a virtual machine. During operation, the system receives a program comprised of instructions that are specified in a machine instruction set architecture of the virtual machine, and translates these instructions into native instructions for the processor that the virtual machine is executing upon. While performing this translation, the system inserts one or more safepoints into the translated native instructions. The system then executes these native instructions on the processor. During execution, if the system detects that an exception was signaled by a native instruction, the system reverts the virtual machine to a previous safepoint to ensure that the virtual machine will precisely emulate the exception behavior of the virtual machine's instruction set architecture. The system uses a gated store buffer to ensure that any stores that occurred after the previous safepoint are discarded when reverting the virtual machine to the previous safepoint.
