Abstract: Provided is a method capable of providing an improved response property appropriate for the characteristics of a system by automatically choosing an interrupt handling mode used for each device. The method is a method in which the embedded operating system kernel determines a handling mode for all individual interrupts, the method includes: dividing interrupt handling modes into a first interrupt handling mode and a second interrupt handling mode which has a different process speed from the first interrupt handling mode, and variably determining a distribution ratio in which each of the interrupts are distributed to the first interrupt handling mode or to the second interrupt handling mode according to a predetermined process condition during boot-up.

Abstract: The present invention relates generally to a method and apparatus for initializing an embedded device. When a boot loader is executed and a kernel is loaded, an initialization program is executed, and a booting sequence including information about an operating sequence of a boot process is loaded. Thereafter, initialization functions which are included in a script replacement function module of the embedded device are executed, and then a state of the embedded device is set to a usable state. Accordingly, the method and apparatus can efficiently perform the operations of an initialization program that is used to solve the complexity of the initialization of an OS inevitably appearing on mobile devices and high-performance embedded devices, and an initialization script that is operated to flexibly execute the initialization program on various devices having different characteristics.

Abstract: Exemplary embodiments of the present invention can reduce physical memory usage of programs executed in an operating system by immediately releasing an allocated memory region at the time of a request of unloading the memory region if it is determined that the memory region which is allocated by programs executed in the operating system becomes unnecessary. A method for memory management includes making a request of unloading a memory region from programs; reclaiming a physical memory region allocated to the programs; and maintaining a record of the memory region that the programs intend to use.

Abstract: Provided is an adaptive process scheduling method for embedded Linux. The adaptive process scheduling method includes calculating a central processing unit (CPU) occupancy time of each of one or more processes, determining whether or not it is necessary to perform adaptive process scheduling, calculating a predetermined weight to be applied to the CPU occupancy time of each process when it is determined that it is necessary to perform adaptive process scheduling, and applying the predetermined weight and updating the CPU occupancy time of each process when it is determined that it is necessary to perform adaptive process scheduling. Accordingly, the adaptive process scheduling method can improve the performance by omitting an unnecessary context exchange compared to the related art and can dynamically cope with an abrupt increase in the number of processes.
