摘要:
Provided are a booting apparatus and method using a snapshot image. A snapshot image may be divided into a plurality of blocks. Each of the blocks may be stored in a nonvolatile memory in a compressed or non-compressed format. The snapshot image may be incrementally loaded in units of the blocks during booting. The loading and decompression of the blocks may be performed in parallel.
摘要:
A technique for reducing a size of a snapshot boot image by adjusting a structure of the snapshot boot image based on an analysis of a computing system. In addition, according to the technique, the overriding portions of a snapshot based boot image may be loaded first in consideration of a time of use of the system, and therefore a boot time can be reduced.
摘要:
A method and apparatus for inputting and outputting data by using a virtualization technique are provided. The method includes generating a virtual operating system (OS) for the external device, which is connected to a host, based on OS information stored in the external device, setting a partial area of a storage of the host as virtual storage for the external device, and storing the data in the virtual storage or a memory of the external device in response to a request for inputting and outputting the data from the virtual OS.
摘要:
An implantable medical device (IMD) is provided. The IMD includes a medical procedure performing unit configured to perform a medical procedure inside a body of a user, a code generating unit configured to detect a motion state of the user, and to generate a motion code that represents a user's intention based on the detected motion state, and a control unit configured to control the medical procedure of the medical procedure performing unit based on the generated motion code.
摘要:
Provided is a method of booting a computing system which performs boot image transmission and device initialization in parallel. For example, using an Internal RAM and direct memory access (DMA), hardware initialization and loading of boot image from a main storage medium to a main memory are performed in parallel, thereby reducing time spent on booting.
摘要:
An apparatus and method for synchronizing a snapshot image are provided. A synchronization page is detected based on whether a page fault is generated in a snapshot page that is part of a snapshot image and based on attributes of a process that generated the page fault. The detected synchronization page is reflected in the snapshot image at a specific time.

摘要:
A virtual machine monitor and a scheduling method thereof is provided. The virtual machine monitor may operate at least two domains. The virtual machine monitor may include at least one run queue and a plurality of schedulers, at least two of the plurality of schedulers comprising different scheduling characteristics. The virtual machine monitor may insert a task received from the domain into the run queue and may select a scheduler for scheduling the task, which may be inserted into the run queue, from the schedulers, according to an event type.
摘要:
Provided is a memory management method, and an apparatus to perform the method, which achieves a shortened user waiting time in consideration of system performance. The method includes acquiring a deallocation unit used to deallocate an allocated memory area according to at least one attribute, and deallocating the allocated memory area using the deallocation unit.
摘要:
A system for executing a program using a virtual machine monitor and a method of controlling the system are provided. The system includes a virtual machine monitor which divides an operating system (OS) into at least one root domain and a plurality of domains having different trust levels, and a trust-management module which is included in the at least one root domain and which periodically measures the trust level of an application program currently being executed in the plurality of domains. The virtual machine monitor executes the application program in one of the domains based on the trust level of the application program.
