IAR Systems updates development tools for ARM Cortex-M7 devices


IAR Systems shortens build times in leading development toolchain for ARM-based devices.


Version 7.40 of the incredibly-popular IAR Embedded Workbench for ARM has introduced support for ARM Cortex-M7 microcontrollers from Atmel. Beyond that, the tools now feature parallel build for shorter build times, as well as an integration of IAR Systems’ new tool C-STAT for powerful static code analysis.

As you know, the ARM Cortex-M7 processor is the most recent addition to the ARM Cortex-M family. Not only focused on energy efficiency and high-performance, the MCUs are intended for use in a wide-range of applications including automotive, industrial automation, medical devices, and of course, the burgeoning Internet of Things.

The new version of IAR Embedded Workbench adds support for ARM Cortex-M7 devices from Atmel, including support for the double precision floating point unit. This covers the recently-revealed Atmel | SMART SAM E70, SAM S70 and SAM V70. In addition to these MCUs, support for a number of ARM Cortex-based devices from several other vendors have also been added.

In order to speed up build times, version 7.40 introduces parallel build. Users can easily set the compiler to run in several parallel processes and make better use of the available processor cores in the PC. This feature can have a major impact on reducing the build times of the compiler.

The add-on product C-STAT for powerful, integrated static code analysis is now available. Static analysis finds potential issues in code on the source code level and can be used to prevent errors such as memory leaks, access violations, arithmetic errors and array and string overruns. The analysis performed by C-STAT improves code quality and aids alignment with industry coding standards. It checks compliance with rules as defined by MISRA C:2004, MISRA C++:2008 and MISRA C:2012, as well as hundreds of rules based on CWE (the Common Weakness Enumeration) and CERT C/C++, for example. Users can easily select the rule set or individual rules to check their code against, and the analysis results are provided directly in the IAR Embedded Workbench IDE.
