C compiler for RH850 automotive MCUs supports ISO 26262
This microcontroller family from Renesas provides high performance balanced with very low power consumption over a wide and scalable range of products. The family provides rich functional safety and embedded security features needed for new and advanced automotive applications. It offers a range of CPU core structures (single, multiple, lock-step and combination thereof) to support high performance and/or high reliability requirements. The new Tasking VX-toolset supports all currently available RH850 devices. Altium will continue to work with Renesas to support future RH850 variants to ensure the delivery of Tasking’s multi-core support features developed in collaboration with Altium’s Tier-1 automotive customers.
The Tasking VX-toolset for RH850 is claimed as the first compiler to incorporate support for the latest MISRA C:2012 guidelines for C programming, in addition to the MISRA C:1998 and C:2004 guidelines. Tasking’s MISRA C support enables developers to select the MISRA rules to enforce and configure the MISRA guidelines in accordance with the company’s prescribed rules in order to increase code safety, reliability and maintainability. By providing support for MISRA C:2012, developers now can benefit from the latest guideline improvements that can reduce the cost and complexity of compliance, whilst aiding consistent, safe use of C in critical systems.
Features of the TASKING VX-toolset for RH850 include:
- Eclipse-based IDE with integrated compiler and debugger;
- Efficient code generation, allowing for fast and compact applications;
- Integrated code analysers for MISRA-C:1998, C:2004 and C:2012 guidelines;
- CERT C secure coding standard;
- Profiling through code instrumentation and run-time error checking capabilities;
- Configurable linker with versatile script language for optimal memory control.
Tasking’s ISO 26262 Support Program is available for the RH850 toolset release, offering various cost and lead-time efficient solutions to help customers achieve certification for functional safety standards such as ISO 26262 and others. The manufacturer of an electronic (sub)system is responsible for obtaining certification credit. As part of this process the manufacturer has to assess the required level of confidence in the software tools used, which is enabled by Altium through a Compiler Qualification Kit as well as optional ISO 26262 Compiler Qualification Services.
”With the RH850 architecture Renesas has built a microcontroller family that has gained a lot of recognition amongst our automotive customers, resulting in a strong interest for Tasking’s robust and efficient VX compiler technology to support the RH850 series”, says Harm-Andre Verhoef, Tasking Product Manager at Altium. “Thanks to close cooperation with Renesas in the development of the new VX-toolset, as well as our ability to develop a compiler that works independently from compilers for other architectures, we have been able to create a stable and highly optimised compiler for the RH850 in a very short time.”
Tasking’s Viper technology used in the RH850 compiler ensures compatibility to other Tasking toolsets and eases application migration from other architectures. The Viper compiler provides a caching functionality which saves the compiler’s intermediate results in order to avoid full compilations, enabling short project build times of embedded applications and saving developers both time and cost.
