Abstract:
PURPOSE: A priority re-defining for saving scheduling time, a delay queue management method, and a system performing the method are provided to save scheduling time of the operating system and reduce memory resources of a system. CONSTITUTION: An initial priority in a priority area supported in an operating system is stored in a task. A priority for redefinition in the task is calculated using the initial priority. Priority allocated on the task based on the initial priority which is pre-defined by the operation system is re-defined(S101). The number of ready queues for performing the task according to the number of the re-defined priorities is determined(S102).
Abstract:
A method for providing a virtual personal computer environment and a mobile memory device therefor are provided to execute an OS that a user wants in an OS of a real PC. A storage module(210) stores a file system about one or more selectable guest OSs. A virtual PC module(220) executes a usage object guest that the user selects in the guest OS on a host OS of a PC by operating a virtual PC application. If the user connects a mobile memory device(200) to the PC, a connection module(230) of the mobile memory device transceives data with the PC through a predetermined communication protocol.
