IAR Embedded Workbench Version 5.30

IAR Systems has developed Version 5.30 of its IAR Embedded Workbench for ARM technology, its integrated development environment (IDE) for building and debugging embedded applications. This latest version introduces new debug capabilities for ARM Cortex-M3 processors that were previously only available in dedicated devices and costly debug probes.

In addition, Version 5.30 supports source code compliance checking to the MISRA-C:2004 standard, for high integrity applications such as automotive as well as support for the ARM Cortex Microcontroller Software Interface Standard (CMSIS).

Display and analysis of Cortex-M3 processor SWV/SWO data is greatly simplified. For example, a statistical function profiler based on the Cortex-M3 processor PC sampler makes it easy to find hot spots and CPU intensive functions in an application, and a disassembly window, featuring an instruction trace count, gives simplified code coverage functionality.

A new Data Log window logs accesses to up to four different memory locations or areas, and includes time information. In addition, an Interrupt Log window now logs entrances and exits to and from interrupts, including time information. A time scale for each interrupt source is displayed in a Graph window.

The compiler optimiser has been tuned to generate code size for Cortex-M3 code. The linker can also now compress initialised data to minimise demands on flash memory: the compressed data will be automatically uncompressed when moved from flash to RAM by the start-up code.

The latest evaluation version of IAR Embedded Workbench for ARM Cortex-M3 processor can be downloaded at www.iar.com/downloads.
