The HX77 series is a highly integrated, low-power image processing SoC based on RISC-V architecture, integrating comprehensive video input/output interfaces, image processing, and system control capabilities. By leveraging an innovative heterogeneous computing architecture and sophisticated power management technology, HX77 has successfully achieved a technological breakthrough that enables 2K@60fps output with mere milliwatt-level power consumption. HX77 has also realized the 3DoF hover feature on end devices through spatial computing. In addition, the SoC supports multiple display interfaces, including MIPI, LVDS, and DP/eDP, and can flexibly adapt to various display topologies, enabling dual-screen independent display and other typical AR use cases across various AR/VR glasses and display devices.
