Abstract: PURPOSE: A multimedia data pre-processing apparatus for VM(Virtual Machine) and a method thereof are provided to reduce time for processing multimedia data, thereby rapidly executing an application. CONSTITUTION: A detection unit(201) detects multimedia data included in an application. A generating unit(202) generates a thread processing the multimedia data. The allocation unit(203) assigns the thread to an idle core. The detection unit confirms an attribute indicating the multimedia data included in a code of the application and detects the multimedia data based on the attribute. The thread decodes the multimedia data into a format able to be processed by the application. The detection unit confirms the code of the application and detects the name of the multimedia data.

Abstract: PURPOSE: An effective JITC performing method in a multicore environment is provided to support JITC requests by sharing a main thread and a thread performing a JITC and efficiently utilizing a multicore. CONSTITUTION: A JITC thread with a relatively lower priority than a main thread is generated if a compile request about a predetermined code section is received among performing the application(S200). The JITC thread is performed if the idle time of the main thread or the machine code of the JITC thread is necessary(S300). A machine code generated by performing the JITC thread is stored in a code cache(S400).
Abstract translation: 目的：提供多核环境中有效的JITC执行方法，通过共享主线程和执行JITC的线程并有效利用多核来支持JITC请求。 构成：如果在执行应用程序之间接收到关于预定代码段的编译请求，则生成具有比主线程优先级低的JITC线程（S200）。 如果需要主线程的空闲时间或JITC线程的机器代码，则执行JITC线程（S300）。 通过执行JITC线程生成的机器代码被存储在代码高速缓存中（S400）。

Abstract: 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.
Abstract translation: 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。

Abstract: PURPOSE: An interpreter call method for a byte code-to-c ahead-of-time compiler is provided to perform rapid function calls like a standard C function call. CONSTITUTION: While performing AOTC(Ahead-Of-Time Compiling), a JAVA method is converted into a C function and includes an interpreter call code. If a callee interpreter is called in the AOTC C function, a call and return about the callee is performed using an interpreter call code. If a AOTC callee C function is called in the AOTC callee C function, the callee C function is called and returned according to the standard C call.
