This additional functionality is ideal for systems where applications are loaded dynamically. When position-independent code and read-only data (ROPI) is used, IAR Embedded Workbench for RH850’s compiler generates code that uses PC-relative references for addressing code and read-only data. The linker places the code and read-only data at fixed locations, but the application will still be executed correctly when the image is placed at a different address. Typical applications for dynamically loaded applications within the automotive industry include, for example, when using the capability of the application to upgrade its own firmware over CAN.
IAR Embedded Workbench includes a functional safety edition certified by TÜV SÜD according to IEC 61508, ISO 26262 and EN 50128. The flexibility of IAR Workbench is extended to the build environment as the build tools supports implementation in Linux-based frameworks for automated application build and test processes. The tools allow large-scale deployments of critical software building and testing and are suitable for installations ranging from a few licenses on a small build server, to massive installations with several hundreds of parallel builds active at the same time.
The toolchain is compliant with the latest C language standard ISO/IEC 9899:2018 and the latest C++ standard ISO/IEC 14882:2017, ensuring high-quality, future-proof code. To simplify peripheral setup, IAR Embedded Workbench for RH850 supports the Renesas Smart Configurator tool, which enables automatic generation of control programs for peripheral modules, and pin setting from the GUI with built-in cross-checks to avoid potential contention with multiplexed functions.
