Abstract: Proposed are an apparatus and a method for simulating charge and discharge energy in an intermittent computing system. Specifically, an operation method for simulating power instability in intermittent computing includes receiving at least one selected from a group of energy storage and SBC standard information of an intermittent computing system, energy consumption information for an application program of the intermittent computing system, and illuminance information, and generating an intermittent computing charge and discharge energy scenario model on the basis of the received information, and performing intermittent computing energy simulation on the basis of the generated model, and identifying whether a result of the simulation is appropriate.

Abstract: Disclosed herein are an apparatus and method for displaying images. The apparatus includes a first image output unit, a second image output unit, an image signal selection unit, and an image display unit. The first image output unit is set to master operation mode, and outputs an image signal to be displayed. The second image output unit is set to slave operation mode, and, if the first image output unit has failed, is switched to master operation mode and then continuously outputs the image signal or a new image signal. The image signal selection unit compares the IP source address of a received master message with previously stored address information, and then selects the image signal that is received from the first image output unit or the second image output unit that has a matching address. The image display unit displays the selected image signal.

Abstract: A method for transiting an operation mode of a routing processor is provided, which allows each routing processor in a packet processing system to be transited among a slave operation mode, a slave stand-by mode, a master stand-by mode, and a master operation mode to allow the packet processing system to normally operate even though a failure occurs in the routing processor that is set in the master operation mode, a new routing processor is added, or the routing processor set in the master operation mode is initialized.
