The ARM Compiler 6 safety package simplifies safety certification while also giving developers at automakers and autonomous system OEMs an efficient C and C++ code-generation tool for ARM-based hardware platforms.
ARM Compiler, the company comments, is already widely used in functional safety today in sectors such as medical, avionics, industrial, railway, energy and automotive. ARM engineering has now built on that expertise and further tuned the new compilation toolchain for an increasingly diverse range of safety-related applications across the ARM Cortex-A, Cortex-R and Cortex-M processor families. While ADAS and autonomous driving push the envelope of runtime performance and compute power requirements, systems such as medical devices require minimal memory footprint and high energy efficiency. ARM Compiler 6, ARM asserts, delivers on both. On particular synthetic automotive and industrial workloads, for instance, code built with ARM Compiler 6 runs as much as 30% faster than when built with its previous generation, ARM Compiler 5. Further improvements to code size optimization and the tiny C Microlib library enable the toolchain to be used in even the most tightly memory-constrained embedded applications.
The safety package will include the certificate and related reports from TÜV SÜD, once the assessment is complete, confirming that ARM Compiler 6 meets the highest level of tool qualification requirements for ISO 26262 (automotive), IEC 61508 (industrial), EN 50128 (railway) and IEC 62304 (medical). This means it can be used at any safety integrity level without further qualification efforts in such applications when the qualification kit’s recommendations are followed. The kit, containing a comprehensive set of instructions, safety manual and reports, can also be used as evidence for justifying toolchain selection irrespective of the safety standard targeted. Finally, to ensure peace of mind over the lifetime of safety systems, the certified compiler branch will receive stability patches and bug fixes over an extended maintenance period.
The ARM Compiler 6 safety package will be available as a standalone product, as well as included in ARM DS-5 Development Studio Ultimate (all ARM architectures) and Keil MDK-Professional (Cortex-M devices), from Q2 2017.
