IAR Systems has released version 5.20 of IAR Embedded Workbench for ARM that offers significant number of improvements focusing on the ARM Cortex-M3 core.

On the debug side, support is implemented to handle trace packets sent over the SWO channel which is part of CoreSight, the on-chip debug and trace solution used in the Cortex processor family. The user has full freedom to configure the types of packets that should be displayed by IAR C-SPY debugger. Additionally debug log messages from a print output can be sent over the SWO channel and displayed by IAR C-SPY, without having to halt the execution.

In addition, the new version of the IAR Embedded Workbench for ARM incorporates several performance oriented improvements. As a part of these improvement efforts, execution speed optimizations for the ARM Cortex-M3 core has been strengthened and in addition, a new multi-file compilation feature allows the compiler to treat several files as one compilation unit which means it can optimize over a larger scope of code.

IAR Embedded Workbench for ARM also incorporates a highly optimizing ARM compiler supporting C and C++, and provides extensive support for a wide range of ARM devices, hardware debug systems and RTOS. Generating very compact and efficient code, it also includes ready-made device configuration files, flash loaders and over 1,000 example projects. ARM EABI compliance means that the tool is compatible with other ARM EABI compliant compilers. Run-time libraries are provided, including source code, and the compiler features relocating ARM assembler, and linker and librarian tools, as well as the integral C-SPY debugger that features an ARM simulator, JTAG support and support for RTOS-aware debugging on hardware, for which optional IAR J-Link and IAR J-Trace hardware debug probes are available.

Included in the Version 5.20 package is an evaluation edition of IAR PowerPac RTOS, file system, TCP/IP and USB stack bundle. Third party RTOS plugins are also available from IAR Systems and RTOS vendors.

"IAR Embedded Workbench for ARM has always been noted for its ease of use, especially for debugging, and for the efficiency of the code it produces, and the latest version 5.20 can only enhance this reputation," commented Mats Ullstr?m, product director of IAR. "With a comprehensive range of ARM cores and devices supports, and evaluation boards available from a wide range of manufacturers, the developer's needs continue to be our top priority."
