Abstract: Methods and an apparatus for dynamic best fit compilation of mixed mode instructions are provided. In one embodiment, a provided method includes receiving a non-native software instruction at a device, generating a first native software instruction from a first instruction set based on the non-native software instruction, the generation of the first native software instruction occurring at the device, executing the first native software instruction at the device, generating a second native software instruction from a second instruction set based on the non-native software instruction, the generation of the second native software instruction occurring at the device, and executing the second native software instruction at the device.

Abstract: A compiler with power and/or energy optimization, a complementary runtime manager, and system having the compiler and/or the runtime manager are described herein.

Abstract: Voltage and frequency scaling techniques that are based upon monitored data are provided. The techniques may be used to better manage the power and energy consumption of a processor in an embedded system, such as a cellular telephone, personal data assistant, smart device, or the like. The techniques may be used with processors that offer a performance monitoring capability. The performance monitor may monitor thread-level utilization at runtime. Instructions per cycle and memory references per cycle are example metrics that may be monitored by the performance monitor. The voltage and frequency scaling techniques may adjust the operating voltage and operating frequency of the processor based on the values of these two metrics. For example, the techniques may include accessing a voltage and frequency scheduler lookup table. The techniques may be employed with non-embedded systems, as well, embedded systems.

Abstract: A method for off loading resource intensive compilations is disclosed. The method may include enabling a user of a wireless handheld device to request a platform independent application. The wireless handheld device may be enabled to assess a resource on the wireless handheld device and to determine whether to request native code for the platform independent application. The method may also include enabling the requested platform independent application to be routed to a trusted server. The trusted server may compile the platform independent application into native code for the wireless handheld device and may transport the native code to the wireless handheld device for execution.

Abstract: An arrangement is provided for selectively loading and executing an assembly based on platform capabilities. When an application that includes at least one platform capability-dependent assembly realized to perform a function is initiated on a platform of a device, the platform capabilities supported by the device are determined based on corresponding platform capability profiles. Based on the supported platform capabilities, specialized assemblies designed to perform an underlying function on a platform having the supported capabilities are selected. Proxies corresponding to selected specialized assemblies are then accordingly invoked to load and excuting the specialized assemblies.

Abstract: Persistent cache apparatus and methods are disclosed. An apparatus and method for caching machine code receives intermediate language code in a just-in-time compiler and just-in-time compiles the intermediate language code to generate machine code. The apparatus and method stores the machine code in a non-persistent cache within a runtime environment and also stores the machine code in a persistent cache coupled to the runtime environment.

Abstract: Test cases are embedded in one or more routines in the code for a software program. Each test case may be designated with a keyword-like descriptor, and includes input and expected output values. A test code discovery and generation module generates test code for each test case, which then may be compiled and executed by a processor.

Abstract: Data from two or more web sites may be aggregated on a local processor-based system. The aggregated data may then be forwarded to a wireless device. In this way, the aggregated data may be communicated to the wireless device in a single connection session.
