In this paper, we present the world's first single-chip field-programmable gate array holographic video processor. It makes 16 computer-generated color holograms of resolution 1920 × 1080 in a second. It uses an off-the-shelf commercial liquid crystral display for the spatial light modulator. To build a single-chip holographic video processor, we used a layer-based computer-generated hologram (CGH) algorithm and a hardware efficient CGH architecture using fixed-point arithmetic. The single-chip holographic video processor provides moving color holograms with low cost, a small footprint, and high energy efficiency. With these characteristics, the holographic video processor will enable the widespread use of holographic applications including mobile and wearable applications.
