Khronos releases ‘OpenGL SC 2.0’ for system safety certification

Published: April 20, 2016 | Munich, Germany

The Khronos™ Group has recently developed the OpenGL® SC 2.0 specification for bringing programmable graphics to systems that require system safety certification. The OpenGL SC 2.0 API specification has been introduced to address the unique and stringent requirements of high reliability display system markets, including FAA DO-178C and EASA ED-12C Level A for avionics, and ISO 26262 safety standards for automotive. Building on the large number of worldwide customer deployments and successful avionics certifications using OpenGL SC 1.0, OpenGL SC 2.0 enables high reliability system manufacturers to take advantage of modern graphics programmable shader engines while still achieving the highest levels of safety certification.

About OpenGL SC 2.0

OpenGL SC 1.0 defined a safety critical subset of the OpenGL ES™ 1.0 fixed function graphics pipeline. OpenGL SC 1.0 shipped in 2005, with minor updates to OpenGL SC 1.0.1 in 2009. OpenGL SC 2.0 is a subset of OpenGL ES 2.0 that includes GLSL-based programmable shaders to enable enhanced graphics functionality, with increased performance and reduced power. It removes all debug functionality from OpenGL ES 2.0 but incorporates the OpenGL robustness extension into the core specification for scheduling and memory access integrity. OpenGL SC 2.0 is designed to be both deterministic and testable while retaining compatibility with existing silicon, enabling the immediate deployment of high-volume desktop, mobile and embedded silicon solutions.

OpenGL SC 2.0 marks the start of a new era of Safety Critical standards by the Khronos group to address a growing industry need for safety critical technologies,” says Erik Noreke Technology Visionary and chair of the Safety Critical working group. “With smart technologies becoming more and more prevalent in daily life with such things as autonomous vehicles and operator assistance, I am proud to be part of the Khronos effort to deliver the safety critical standards for not only high performance graphics, but also compute and vision.”

Future Safety Critical Standards

Visual computing acceleration will be a vital component of many emerging safety critical market opportunities including Advanced Driver Assistance Systems (ADAS), autonomous vehicles and new generation avionics systems. The Safety Critical working group at Khronos has a remit to develop safety critical versions of other Khronos specifications, including Vulkan™ for high-efficiency graphics and compute. The OpenVX™ working group at Khronos is also developing a safety critical version of this standard for low power vision processing. The Safety Critical working group will build on the experience of shipping OpenGL SC, but is also looking to develop cross-API guidelines to aid in the development of open technology standards for Safety Critical systems. Any interested company is welcome to join Khronos for a voice and a vote in this development process.
