Ces compilateurs s'intègrent dans l'environnement de développement IAR Embedded Workbench qui inclut également une gestion de projet et un éditeur.
IAR Embedded Workbench offre ainsi la même interface utilisateur quelque soit le processeur que vous avez choisi d'utiliser.

IAR Embedded Workbench provides a completely integrated development environment including a project manager, editor, build tools and the C-SPY debugger. In a continuous workflow, you can create source files and projects, build applications and debug them in a simulator or on hardware.

IAR Systems is well known for its highly optimizing compilers. Every C/C++ compiler contains both generic global optimizations as well as low-level chip-specific optimizations that ensure a small code size while taking advantage of all the specific features of your selected device.

IAR Embedded Workbench offers the same intuitive user interface regardless of which microcontroller you have chosen to work with—coupled with general and target-specific support for each device.

Whether you have a tight project schedule or are just eager to get started, IAR Embedded Workbench contains everything you need to get going:

- ready-made C/C++ and assembler peripheral register definition files
- ready-made project templates and sample projects
- context-sensitive online help with library function lookup
- comprehensive, printed user documentation

Both the user documentation and the GUI is available in English.

Each C/C++ compiler from IAR Systems uses the same naming convention which facilitates reuse of code and migration from one chip to another, especially when moving to high-end architectures.
