摘要:
A method and system of informing a micro-sequence of operand width. At least some of the illustrative embodiments may be a method comprising fetching a first opcode, asserting a flag if the first opcode modifies an operand width of a subsequent opcode, fetching a second opcode, triggering a micro-sequence based on the opcode, reading the flag by instructions of the micro-sequence, and fetching an operand of the second opcode by the micro-sequence (the bit width of the operand based on a state of the flag).
摘要:
A processor adapted to couple to external memory. The processor comprises a controller and data storage. The data storage is usable to store local variables and temporary data and is configurable to operate in either a cache policy mode in which a miss results in an access of the external memory or in a scratch pad policy mode in which a miss does not result in an access of the external memory. The data storage comprises first and second portions, and wherein only one of said portions is active at a time for storing said local variables. When the active portion does not have sufficient capacity for additional local variables, the other portion becomes the active portion for storing local variables. When one portion is the active portion, the other portion is used to store the temporary data and such other portion is sufficiently large to contain the temporary data.
摘要:
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.
摘要:
A system comprising a compiler that compiles source-level code to generate an intermediate-level instruction comprising a predetermined component. The intermediate-level instruction is an at least partially optimized version of the source-level code. Execution of the predetermined component triggers the execution of a series of instructions that, when executed, generates previously-unavailable data that is used to re-generate the intermediate-level instruction. The re-generated intermediate-level instruction has a length less than or equal to that of the intermediate-level instruction.

Methods, computer-readable media, and systems for dynamic address translation between a source memory space and a target memory space are provided. In some illustrative embodiments, a method is provided for copying data from a source memory space to a target memory space. The method includes extracting a plurality of source data units, each of size s bits, from the source memory space and translating the plurality of source data units into a plurality of target data units. A target data unit is an addressable unit of the target memory space and each target data unit is of size t bits. The method further includes copying the plurality of target data units into a plurality of contiguous transfer units, each of size b bits, in the target memory space.
摘要:
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.
摘要:
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.
摘要:
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).
摘要:
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.
