DiSTI Corporation’s GL Studio is an HMI toolchain aimed at embedded teams that need one UI design to survive the jump from prototype to production, across automotive, avionics, medical, and other regulated targets. It’s used to build instrument clusters, infotainment, and head-up displays with real-time interactivity, while keeping the runtime portable across silicon and operating systems. https://www.disti.com/gl-studio/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

A core theme here is functional safety: GL Studio includes a safety-critical code generator and runtime library built around requirements traceability, verification/validation, and independent assessment, so UI logic can be argued and audited like any other safety feature. Chris Giordano calls out certification paths spanning DO-178C for avionics (with DO-330 TQL-1 tool qualification) and ISO 26262 work for automotive, and frames “safety critical” as proving every line of code behaves as specified, with regression tests and reviews tied back to the original requirements to reduce certification risk.
The demo, recorded at Embedded World 2025 North America, runs on a Toradex Verdin i.MX95 platform under both Yocto Linux and QNX, with an OpenGL ES graphics stack. Instead of a canned loop, the UI is driven live: zooming into quad views, walking through sub-menus, triggering declutter animations, flipping into navigation-style screens, and switching languages (including Korean) to show how localization and layout can stay coherent in motion on a show floor.
A practical engineering point is hardware/OS agnosticism: the same runtime is meant to land on many SoCs and RTOSes, and the setup shown layers the OS, graphics middleware, and the GL Studio app layer cleanly on top of reference hardware such as a Telechips Dolphin 5 Plus, with safety-oriented GPU classes like Arm Mali G78AE in the mix. The conversation also highlights that in space and some defense programs, “just use a GPU” can be unrealistic because rad-hard GPU options are limited, so a UI toolchain needs credible paths for constrained or CPU-heavy rendering while still preserving testability, determinism, and safety evidence along that path.
For even tighter devices, GL Studio Micro targets MCU-class systems that may have no OpenGL support at all, aiming for responsive graphics with a small footprint and fast startup. The broader takeaway is that modern HMI work is as much about certification artifacts, portability, and predictable runtime behavior as it is about pixels, which helps explain why the same toolchain shows up in vehicles from Jaguar Land Rover and Hyundai/Kia to safety-critical programs today.
