264 results about "Runtime system" patented technology

In computer programming, a runtime system, also called run-time system, runtime environment or run-time environment, primarily implements portions of an execution model. This is not to be confused with the runtime lifecycle phase of a program, during which the runtime system is in operation. Most languages have some form of runtime system that provides an environment in which programs run. This environment may address a number of issues including the layout of application memory, how the program accesses variables, mechanisms for passing parameters between procedures, interfacing with the operating system, and otherwise. The compiler makes assumptions depending on the specific runtime system to generate correct code. Typically the runtime system will have some responsibility for setting up and managing the stack and heap, and may include features such as garbage collection, threads or other dynamic features built into the language.

Integrating operating systems and run-time systems

The Virtual Machine is viewed by many as inherently insecure despite all the efforts to improve its security. This invention provides methods, apparatus, and computer products to implement a system that provides operating system style protection for code. Although applicable to many language systems, the invention is described for a system employing the Java language. Hardware protection domains are used to separate Java classes, provide access control on cross domain method invocations, efficient data sharing between protection domains, and memory and CPU resource control. Apart from the performance impact, these security measures are all transparent to the Java programs, even when a subclass is in one domain and its superclass is in another, when they do not violate the policy. To reduce the performance impact, classes are grouped and shared between protection domains and map data lazily as it is being shared. The system has been implemented on top of the Paramecium operating system used as an example of an extensible operating system application.

Apparatus and method for profiling system events in a fine grain multi-threaded multi-core processor

A system and method for profiling runtime system events of a computer system may include associating a data source type with detected system events. The system events may be detected dependent on information included in a reply message received by a processor in response to a data request or other transaction request message. The reply message may include information characterizing a source type of a source of data included in the reply message. The source type information may indicate that the source is remote or local; that it is a shared or a private storage location; that the data is supplied via a cache-to-cache transfer; or that the data is sourced from a coherency domain other than that of the requesting process. Instructions, events, messages, and replies may be sampled, and extended address information corresponding to the samples may be stored in an event set database for performance analysis.

System and methodology for dynamic application environment employing runtime execution templates

A dynamic application environment or system is described that includes a client, a run-time system, and a back-end database. The client comprises a workstation or desktop PC running browser software, such as Microsoft Internet Explorer or Netscape Navigator. The back-end database comprises a back-end (e.g., server-based) database system, such as an SQL-based database system. The run-time system includes a collection or repository module for storing “presentation templates,” a Template Services Module or engine, a Template Parameters Module, and a Database Accessor Module. The presentation templates are employed for presentation of the application to the user interface (at the client). At application run-time, the templates are provided to the Template Services Module, which includes a Template Manager and a Template Parser. These provide generic processing of the templates, which may be assembled to complete a finished product (i.e., run-time application). For instance, the Template Services Module knows how to load and parse a template and then look up its parameters, regardless of the application-specific details (e.g., user interface implementation) embodied by the template. In use, the system is deployed with presentation templates that represent the various client views of the target application, for the various platforms that the application is deployed to. In this manner, when new functionality needs to be added to the system, it may simply be added by expanding the run-time library portion of the system.

Common query runtime system and application programming interface

A query runtime architecture and an exemplary application programming interface suitable for the architecture are presented. The architecture inputs one or more XML queries and views and enables the queries to be translated wherein the queries and views may be run over multiple data sources of different data models. The architecture incorporates front-end compilers which convert input queries and views into an intermediate language representation which represents the meaning of the respective query or view. The architecture may then allow the back-end compiling of the intermediate language representation to target languages compatible with the data sources desired to be queried. The architecture also allows the execution of those target compilations to extract the data requested of the queries. The invention also discloses an example application programming interface for the query runtime system.

System and method for distributing updates to runtime systems without destabilizing compatibility

Multiple versions of a runtime system, such as a software emulation application that emulates a legacy hardware architecture, are allowed to co-exist in the memory of a new hardware architecture. The operating system software of the new hardware architecture reads configuration data from a database or table to decide which version of the runtime system is desirable for an application program or game that is being loaded or is currently running, and, if a match is found, only that runtime system is invoked. To reduce storage footprint, the different versions of the runtime system may be stored using “differential patching” techniques. In this configuration, the operating system will always launch the same basic runtime system binary, but it will select a different differential patch to apply at run-time based on the title as determined during the database lookup. In this fashion, future changes to the runtime system to correct software bugs, incompatibility issues, and the like only need to be tested for the relevant target application programs or games.

Scalable runtime system for global address space languages on shared and distributed memory machines

An improved scalability runtime system for a global address space language running on a distributed or shared memory machine uses a directory of shared variables having a data structure for tracking shared variable information that is shared by a plurality of program threads. Allocation and de-allocation routines are used to allocate and de-allocate shared variable entries in the directory of shared variables. Different routines can be used to access different types of shared data. A control structure is used to control access to the shared data such that all threads can access the data at any time. Since all threads see the same objects, synchronization issues are eliminated. In addition, the improved efficiency of the data sharing allows the number of program threads to be vastly increased.

Hybrid electric vehicle

A hybrid electric drive system for an automotive vehicle comprises a heat engine, an electric motor, a one-way-clutch, a torque-limiting clutch, and a transmission. The one-way-clutch disposed between the engine shaft and the motor shaft, and it can transmit torque from the engine shaft to the motor shaft. The transmission has an input shaft being connected to the motor shaft and an output shaft to drive the wheels. The torque-limiting clutch is also disposed between the engine shaft and the motor shaft. When it is disengaged, the torque-limiting clutch disconnects the motor shaft from the engine shaft, so the motor can solely drive the vehicle. When it is engaged, the clutch transmits a pre-determined level of torque from the motor shaft to the engine shaft in order to start the engine. The torque limiting clutch will smooth out the torque peak when the system starts the engine while the vehicle is running.
