The computational power required to display a 3D hologram is about 106 times higher than for a typical 2D display. Moreover, real-time processing of a holographic 3D image, which requires an enormous amount of information, demands parallel and distributed computer systems. “The biggest problem is the computational complexity. It is impossible to create holographic videos even on current high-speed computers,” explains Ito. “Additionally, in conventional parallel computation, the computation speed conversely decreases with the number of parallel calculations.”

Ito and colleagues report their 8th prototype of a holography computing board, HORN-8 (HOlographic ReconstructioN), which integrates large-scale holographic calculation circuits and parallel processing technology. The HORN-8 board is composed of seven computational and one communication FPGA and the circuits are densely packed, allowing for the use of short wires and, thus, enabling parallel computation and fast speed.
