Green Hills expands industrial safety platform

LONDON — Green Hills Software Inc. has enhanced its Platform for Industrial Safety, adding support for the its Secure Virtualization Architecture and expanding the existing networking, file system and target hardware options.

Certified by TUV to Safety Integrity Level 3 (SIL3) of the IEC 61508 safety standard, SIL3 is the highest assurance level achievable for an individual software component, such as an operating system.

The certified INTEGRITY operating system technology forms the core of the Green Hills Platform for Industrial Safety, a comprehensive solution comprised of tools, operating systems, secure guest OS virtualization, services, and middleware aimed at reliability-critical industrial control, transportation, railway, nuclear control and automation systems.

The enhanced industrial safety platform provides support for secure virtualization architecture and additional target processors, such as OMAP35x processors from Texas Instruments (TI) and ARM Cortex-A8. The are additional reference board support packages, wireless supplicant support (WPA/WPA2) and a partitionable journaling file system (PJFS).

There is enhanced wear leveling (a technique for prolonging the service life of some kinds of erasable computer storage media) flash file system support as well as expanded TCP/IP v4/v6 networking stack, security protocols, and networking applications. There are enhanced USB host stack, device stack and communications class drivers.

The secure partitioning capability of INTEGRITY enables software, from non safety-related through safety-critical, to be safely partitioned on a single processor. Each partition can then be certified at its appropriate safety integrity level, eliminating the need for separate physical systems or to certify code beyond the required safety level.

With Green Hills' processor-independent certification, customers have a range of options to choose from allowing design flexibility compared to alternative approaches, and resulting in reduced overall system complexity, product and certification cost.

The Green Hills Software Platform for Industrial Safety includes INTEGRITY and velOSity real-time operating systems (RTOS), with certification by TUV to the International Electrotechnical Commission (IEC) EN 61508 standard at Safety Integrity Level 3 (SIL3); a safety manual; SIL3 certification certificate and report; MULTI Confidence-from-Use report (optional).

IEC 61508 is an international standard for the functional safety of electrical, electronic, programmable electronic (E/E/PE), and safety-related systems and applies to these systems regardless of their applications. It is the basis for a published nuclear sector standard (IEC 61513). It is also currently being used as the basis for developing other sector standards (e.g. machinery, process IEC 61511), along with standards in Railway (EN 50128/CENELEC) and automotive (ISO 26262, draft).
