  • Code generator and method for generating extra code for a virtual machine
    Patent number: 9792132
    Abstract: 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 rearranger and method for rearranging code for a virtual machine
    Patent number: 9262186
    Abstract: 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.

  • Method and apparatus for dynamically generating machine code
    Patent number: 8826251
    Abstract: 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.
