Abstract:
A distributed shared power apparatus of a data center includes a server monitor configured to monitor two or more rack mount servers that generate power by converting incoming alternating current (AC) power into direct current (DC) power and share the generated power with each other, and to collect an available total DC power of each rack mount server and a peak DC power used by each rack mount server; and a sharing controller configured to calculate surplus DC power possessed by each rack based on the collected available total DC power of each rack mount server and the peak DC power used by each rack mount server, and to control power sharing between the two or more rack mount servers based on the calculated surplus DC power of each rack.
Abstract:
The present invention relates to a method and apparatus for performing two dimension fast fourier transform for hologram processing. A method for processing a hologram according to an embodiment of the present disclosure may comprise: generating complex data by multiplying the digital image by a random phase value; performing inverse fast fourier transform (IFFT) processing on the complex data; generating pattern information by multiplying a result of the IFFT processing by a quadrant phase; and processing the hologram based on the pattern information. Here, the IFFT processing may comprise a IFFT core operation that performs row-base IFFT and column-base IFFT on the complex data, and a single shift IFFT operation that applies a predefined rule to a result of one or more of the row-based IFFT or the column-based IFFT.
