A method and compiling device are provided for compiling a software application to be executed on a virtual machine of a physical platform. The software application originally is in the form of a set of codes to be compiled. The method includes a phase of selectively compiling the set of codes to be compiled, outputting a compiled application including a first application part which is executed by the virtual machine using commands from the virtual machine, and a second application part including binary commands which can be executed directly on the physical platform.

A method for providing an online distribution service with an application dedicated to a terminal type. The method includes: identifying a terminal type associated with a terminal connected to the online distribution service, supplying a terminal type identifier; obtaining at least one characteristic of the terminal according to the terminal type; compiling the dedicated application from a generic application according to the at least one terminal type characteristic; and transmitting the dedicated application to the connected terminal.

A method for compiling an original application written in an intermediate code, in which the original application is executed by means of a virtual machine. The method supplies a native application having a native binary code. The method includes: extracting at least one intermediate code instruction at least one corresponding function input point; a first step of compiling the intermediate code of the application to a code that includes control flow management and calls said at least one input point of each function implementing the instructions of the intermediate code; and a second step of compiling the compiled application code and intermediate code functions supplying the optimised native application.

Method for compiling an intermediate code of an application

A method for providing an application by a virtual machine. The method includes a step of compiling an application written in a source code to a native application for a particular platform and a step of transforming the compiled application into a library, wherein the library is made available to the virtual machine.

A method and system for performing dynamic instrumentation. At least some of the illustrative embodiments are methods comprising setting at least one monitor value (wherein the at least one monitor value is associated with a software monitoring handler), detecting a value within a register equal to the at least one monitor value, and executing the software monitoring handler based on the detecting.

The invention relates to a method for fine-tuning a software application that is written in a source programming language and is executable on a target platform. According to the invention, such a method includes: a stage of compiling said software application that is written in said source language and supplies the code of an intermediate software application that is written in an intermediate language, said stage comprising a step of inserting, into the code of said intermediate software application, a specific construction for intercepting events by means of complementary instructions, and a step of formatting the intermediate code of said software application such that the matching of a line of source code with a line of intermediate code is the most frequent possible matching; a stage of compiling the code from said intermediate software application into an executable software application; and a stage for fine-tuning said software application, said stage including at least one step of converting at least one piece of fine-tuning information between a program for fine-tuning said intermediate language and a program for fine-tuning said source language.

A method and system for performing a Java interrupt. At least some of the illustrative embodiments are methods comprising executing a thread having a context on a stack based on a first program counter, detecting an interrupt while executing the thread (wherein execution of the thread is temporarily suspended), and executing a method portion to handle the interrupt (wherein the method portion is executed on the stack based on the first program counter, and wherein the context during execution of the method portion is the same as during execution of the thread).

A method and system of performing Java language class extensions. At least some of the illustrative embodiments are computer-readable mediums storing a program that, when executed by a processor of a host system, causes the processor to identify a first class having a first name, and create a second class based on the first class (the second class is an abstract view of the first class, and the second class has a second name equal to a third name of a third class).

A method and system of performing thread scheduling. At least some of the illustrative embodiments are computer-readable mediums storing a program that, when executed by a processor of a host system, causes the processor to instantiate a CPU object that represents a processor abstraction, create a CPU context object that represents a thread abstraction (wherein the CPU context object is associated to a method, and wherein the CPU context object is mapped onto the CPU object), and execute the method within the CPU object.

A method and system for performing class loader notification. At least some of the illustrative embodiments are methods comprising raising a notification during execution of a first method (the notification based on an event), identifying the first method, and invoking a second method based on the identification of the first method in response to the notification.

JEK class loader notification

A method and system for implementing a micro-sequence based security model in a processor. More particularly, micro-sequences and JSM hardware resources are employed to construct a security model invisible to applications, and when memory constraints are in place, extend a complex security model in JSM code by implementing a micro-sequence security trigger. The method includes micro-sequence based security policy that determines whether an instruction accesses a privileged resource associated with a processor and when not already in privilege mode and not executing a micro-sequence, the micro-sequence based security policy is applied to the instruction to control access to the privileged resource according to the security policy.

Micro-sequence based security model

An electronic device that comprises a processor including an individual instruction and a first group of instructions. The device further comprises a memory externally coupled to the processor, as well as a second group of instructions. When executed, the first group of instructions causes the processor to execute the second group of instructions in lieu of the individual instruction.

A method and system to emulate an M-bit instruction set. At least some of the illustrative embodiments are a method comprising fetching at least a portion of an instruction (the instruction from a first instruction set that is not directly executable by a processor), indexing into a table to an index location (the index location based on the at least a portion of the instruction), executing a first series of instructions directly executable by the processor (the first series of instructions pointed to by the table at the index location), and thereby emulating execution of the instruction from the first instruction set.

Method and system to emulate an M-bit instruction set

A mobile device () manages tasks () using a scheduler () for scheduling tasks on multiple processors (). To conserve energy, the set of tasks to be scheduled are divided into two (or more) subsets, which are scheduled according to different procedures. In a specific embodiment, the first subset contains tasks with the highest energy consumption deviation based on the processor that executes the task. This subset is scheduled according to a power-aware procedure for scheduling tasks primarily based on energy consumption criteria. If there is no failure, the second subset is scheduled according to a real-time constrained procedure that schedules tasks primarily based on the deadlines associated with the various tasks in the second subset. If there is a failure in either procedure, one or more tasks with the lowest energy consumption deviation are moved from the first subset to the second subset and the scheduling is repeated.
