Abstract: The virtualization device according to the present invention includes a virtual machine including a guest kernel and one or more guest user processes and inserting input and output requests for inputting and outputting one or more physical units to a sharing queue; a hypervisor module driving the virtual machine; and a host kernel including one or more device drivers for the physical units. The guest kernel includes one or more device drivers mutually acting with the hypervisor module and an interrupt handler between processors. The hypervisor module includes a polling thread confirming whether there is the input and output request inserted into the sharing queue and transmitting the input and output request to a device emulation thread and the device emulation thread processing the input and output request and transmitting a complete message to a CPU through the interrupt handler between the processors.

Abstract: PURPOSE: A memory reuse method and a device thereof are provided to efficiently release a used memory area by minimizing a waiting time for data processing when there is shared data access by memory accessors. CONSTITUTION: A memory allocator allocates copy sharing data for sharing data to an unused object when there is access to the sharing data by a second memory accessor in a state that a first memory accessor uses sharing data through a part of objects included in a first active block. An active block setting unit(120) generates/sets a second active block and sets a first active block as an inactive block when there is access to the sharing data by the second memory accessor in a state that all of the objects are used. [Reference numerals] (110) Memory allocation unit; (120) Active block setting unit; (130) Memory accessor management unit; (140) Memory canceling unit; (200) Memory area; (210) Block header; (230) Block N; (AA) Block 1; (BB) Block 2
