IAR Embedded Workbench supports new Renesas RX71M MCUs targeting the industrial Internet of Things

New version of IAR Embedded Workbench for Renesas RX adds support for the latest RX devices as well as improved functionality

Uppsala, Sweden—March 23, 2015—IAR Systems® has released version 2.70 of its development toolchain IAR Embedded Workbench® for Renesas RX family of MCUs. In addition to new features including position-independent code and data, version 2.70 adds updated device support and example projects for the latest Renesas devices. The support includes the new Renesas RX71M group with advanced security features for the industrial Internet of Things. Renesas’ RX71M group addresses the critical importance of security in embedded design for industrial equipment where connectivity is added to more and more applications. IAR Systems is the only tool vendor to provide high-performance tools for the entire line-up of Renesas MCUs. In total, more than 4,000 Renesas devices, including all RX devices, are supported by IAR Embedded Workbench.

With the new version of IAR Embedded Workbench for RX comes the possibility of having the IAR C/C++ Compiler™ generate both position-independent code and/or position-independent data. This feature is ideal for developers using operating systems where modules are built completely position-independent and can be located anywhere in memory.

The new version also includes enhancements to the already very efficient code optimization techniques. The optimizations for code size and execution speed provided by the IAR C/C++ Compiler perform on multiple levels, global as well as core/target-specific. The developer is able to tune the optimizations to achieve the best possible configuration for the application at hand. Major functions of the optimizer, such as loop unrolling and function inlining, can be controlled individually, and by setting different optimizations for different parts of the code, the right balance between size and speed can be achieved.

Introduced in the C-SPY® Debugger included with IAR Embedded Workbench is functionality for saving C-SPY Watch window content. Also added is an RTOS-awareness plugin for the Quadros RTXC realtime operating system.
