IAR Embedded Workbench for ARM

IAR Systems has a long and fruitful relationship with ARM. IAR Embedded Workbench for ARM supports all available ARM cores, from all major vendors. Outstanding speed optimizations enable IAR Embedded Workbench to generate the fastest performing code and the shortest possible execution times, delivering best-in-class CoreMark results.

Multicore Debugging, neon vectorization

The latest version of this product, version 7.10, adds multicore debugging and automatic NEON vectorization.

Version 6.70 highlights: examples on demand, improved integration with Freescale Processor Expert, new pragma directives and new device support.

Version 6.60 highlights: support for the I-scope power measurement probe, support for Texas Instruments XDS200, external analyzers and code generation for execute-only code memory systems.

Ready-made device configuration files, flash loaders and 4,300 example projects are included. IAR Embedded Workbench is compatible with other ARM EABI compliant compilers and supports the following ARM cores:
