    • PURPOSE: An additional code generating apparatus for a VM(Virtual Machine) and a method thereof are provided to increase a area able to accelerate through a JITC(Just In Time Compiler) and improve performance of the VM by increasing generation of a machine code. CONSTITUTION: An information collecting unit(201) collects trace information indicating logic flow which a byte code is performed. If the byte code is not compiled, a code decision unit(202) decides a byte code section to compile into a machine code by using the trace information. A compiler compiles the byte code section into the machine code. The compiler and an interpreter performing the byte code are operated on separate cores. The information collecting unit searches for a route of the byte code performed on the interpreter and collects trace information.
    • 目的:提供用于VM(虚拟机)的附加代码生成装置及其方法,以通过增加机器代码的生成来增加能够通过JITC(即时编译器)加速的区域并提高VM的性能。 构成:信息收集单元(201)收集指示执行字节代码的逻辑流的跟踪信息。 如果字节码未被编译,则代码判定单元(202)通过使用跟踪信息来决定字节代码段以编译成机器代码。 编译器将字节码部分编译成机器代码。 执行字节码的编译器和解释器在独立的内核上运行。 信息收集单元搜索在解释器上执行的字节码的路由并收集跟踪信息。

    • PURPOSE: A code relocation apparatus for a virtual machine and a method thereof are provided to remove a related jump instruction caused by relocation of a machine code stored in a code cache, thereby improving execution performance of the machine code. CONSTITUTION: A information collecting unit(201) collects code information indicating a relation of a machine code and a byte code. A code arranging unit(202) relocates the machine code stored in a code cache by using the code information. The code information includes location information, indicating a location where the machine code is stored in the cord cache on, and trace information about the byte code which is a standard of the machine code. The cord arranging unit confirms a logical execution procedure from the trace information and relocates the location of the machine code in the code cache according to the execution procedure.
    • 目的:提供一种用于虚拟机的代码重定位装置及其方法,用于去除由存储在代码高速缓存中的机器代码的重定位而导致的相关跳转指令,从而提高机器代码的执行性能。 构成:信息收集单元(201)收集指示机器码和字节码的关系的码信息。 代码排列单元(202)通过使用代码信息来重新定位存储在代码高速缓存器中的机器代码。 代码信息包括指示机器代码存储在电线高速缓存中的位置的位置信息,以及关于作为机器代码标准的字节码的跟踪信息。 绳索排列单元从跟踪信息确认逻辑执行过程,并根据执行过程将代码高速缓存中的机器代码的位置重新定位。

    • PURPOSE: A display device including a virtual machine and a control method thereof are provided to process an application made with a specific program language received from an external device or broadcast by using the virtual machine. CONSTITUTION: A receiving module(210) receives an application made with a specific program language. A detector detects a first data format included in the application. A translator converts the detected first data format into a second data format processed in an enhanced VM(Virtual Machine)(260). The enhanced VM processes the converted second data format. A video processor(250) converts the converted second data format into data to be outputted.
