In a virtual machine that uses a just-in-time complier (JITC) as a software execution environment, an idle time of a core to which the JITC is allocated is utilized to generate machine code in advance, thereby reducing a load on an interpreter. Accordingly, code execution performance of the interpreter is improved, and the utilization of a multi-core system that executes applications is increased.

Code generator and method for generating extra code for a virtual machine

A multimedia data preprocessing apparatus for a virtual machine is provided. The multimedia data preprocessing apparatus includes a detection unit configured to detect multimedia data included in an application, a generation unit configured to generate a thread for processing the detected multimedia data, and an allocation unit configured to allocate the generated thread to an idle core.

Provided is an code rearranger and method for a virtual machine that uses a just-in-time-compiler (JITC) to manage a location of machine code stored in a code cache. The apparatus may rearrange consecutively-executable machine codes from among those stored in the code cache to be placed successively.

Code rearranger and method for rearranging code for a virtual machine

A method and an apparatus for dynamically generating a machine code is provided, including: sequentially storing generated instructions in a first buffer; sequentially storing data in a second buffer, when the generated instructions reference data; and flushing the first buffer and the second buffer to executable code when a distance between an instruction referencing the data and the data has reached a limit of an offset range of the data-referencing instruction.
