IAR Systems has released a new version of IAR Embedded Workbench for RX, the company's high-performing development tool suite for Renesas RX microcontrollers. IAR Embedded Workbench for RX. Version 2.40 brings highly improved optimizations and also introduces a new text editor and source browser.

The IAR C/C++ Compiler for RX has been tuned to produce better optimized code and the generated code is both smaller in size and substantially faster in execution. Initial tests show more than 30 percent reduced execution times for industry standard test code compared to the previous version. Added to the compiler is also support for the C++ feature Multiple inheritance.

Version 2.40 of IAR Embedded Workbench for RX introduces a new text editor and source browser featuring auto-completion, code folding, block selection, block indenting, bracket matching, and zooming. Character encoding support and word/paragraph navigation have also been improved.

In version 2.40 a C-SPY start/stop function is available for the E1/E20 emulators. The start/stop function makes it possible to execute specified routines of the user application immediately before starting and immediately after halting program execution. Also added is the possibility to define custom SFR's (special function registers) in C-SPY with selectable access size and type.

The new version adds new license features such as commuter licenses, automatic license activation, and support for virtual servers, facilitating license management for global customers.
