Abstract: Disclosed herein are a data processing apparatus for pipeline execution acceleration and a method thereof. According to an exemplary embodiment of the present invention, the data processing apparatus for pipeline execution acceleration includes: a processor configured to sequentially execute a first application program and a second application program reading or writing a specific file; and a file system configured to complete a write for a file data for the specific file to a data block previously allocated from the first application program and provide the file data for the specific file to the second application program prior to executing a close call for the specific file from the first application program, when executing a read call for the specific file from the second application program.

Abstract: Disclosed herein is a method and apparatus for supporting virtualization. In the method, conversion of source code of a loadable module is initiated. A virtualization-sensitive instruction is searched for during the conversion of the source code. If the virtualization-sensitive instruction has been found, a virtualization-sensitive instruction table is generated based on the found virtualization-sensitive instruction. The virtualization-sensitive instruction is substituted with an instruction recognizable in a privileged mode, based on the generated virtualization-sensitive instruction table. The loadable module is loaded and executed in a kernel. Accordingly, the present invention supports virtualization, thus minimizing overhead occurring in full virtualization, and guaranteeing the high performance provided by para-virtualization without modifying a source.
Abstract translation: 这里公开了一种用于支持虚拟化的方法和装置。 在该方法中，启动可加载模块的源代码的转换。 在源代码转换期间搜索虚拟化敏感指令。 如果已经找到了虚拟化敏感指令，则会根据发现的虚拟化敏感指令生成一个虚拟化敏感指令表。 基于生成的虚拟化敏感指令表，以特权模式可识别的指令代替虚拟化敏感指令。 可加载模块在内核中加载并执行。 因此，本发明支持虚拟化，从而最大限度地减少完全虚拟化中发生的开销，并且保证在不修改源的情况下通过半虚拟提供的高性能。
