Abstract: The present invention relates to an apparatus and method for acquiring noise source entropy for a random number generator, which use contention for access to memory between Graphical Processing Unit (GPU) cores. For this, an apparatus for acquiring noise source entropy for a random number generator includes a core calling unit for simultaneously calling a plurality of cores to a critical area, and a noise source entropy generation unit for generating noise source entropy based on a sequence of entry of the plurality of cores into the critical area.

Abstract: A method and apparatus for storing waveform data are disclosed. The apparatus for storing waveform data includes a channel information reception unit, a folder generation unit, a file generation unit, and an analysis information control unit. The channel information reception unit receives waveform data from an external measuring device. The folder generation unit generates a high level folder for each waveform measurement unit of the waveform data, and generates low level folders, in which information of each channel is stored, for the generated corresponding high level folder. The file generation unit generates waveform data files to be stored in the low level folders. The analysis information control unit stores a text file, corresponding to analysis information necessary for subchannel analysis, in the high level folder.
