Abstract: A method for memory management, include allocating an empty page of a physical memory for reference data according to execution of an application program, and mapping the empty page to a virtual memory; checking a physical address of the physical memory to which the reference data has been loaded; mapping the checked physical address to the virtual memory to which the empty page has been mapped, and mapping the reference data; and releasing allocation of the allocated physical memory when the reference data is mapped to the virtual memory.

Abstract: In order to increase the accuracy of status or failure diagnosis of machine tools and reduce the time and costs required for data collection and algorithm development for diagnosis, sensors are mounted on specific elements of the machine tools and measurement data is collected while operating under the specific operating conditions during a time interval between one machining operation and another machining operation to perform status or failure diagnosis of the machine tools. According to the present invention, by using data collected while operating machine tools under the predefined specific conditions using a time interval between one machining operation and another machining operation, it is possible to more accurately perform diagnosis while allowing less noise to be mixed in the data and reducing the time required for data collection for the development of diagnostic algorithm.

Abstract: Disclosed is an apparatus and method of processing input and output in a multi-kernel system. A method of processing input and output in a multi-kernel system according to the present disclosure includes: setting a shared memory between a first kernel on a main processor and a lightweight kernel on a parallel processor; setting a data transmission and reception channel between the first kernel on the main processor and the lightweight kernel on the parallel processor using the shared memory; providing, on the basis of the data transmission and reception channel, an input/output task that occurs in the lightweight kernel to the first kernel on the main processor; processing, by the first kernel on the main processor, an operation corresponding to the input/output task; and providing a result of the processing to the lightweight kernel.

Abstract: Scheduling threads in a system with many cores includes generating a thread map where a connection relationship between a plurality of threads is represented by a frequency of inter-process communication (IPC) between threads, generating a core map where a connection relationship between a plurality of cores is represented by a hop between cores, and respectively allocating the plurality of threads to the plurality of cores defined by the core map, based on a thread allocation policy defining a mapping rule between the thread map and the core map.
