Make sure your code is the best it can be. Our compiler makes it fast, effective and highly compact. And powerful code analysis ensures its quality. The compiler and the debugger of IAR Embedded Workbench are by many considered the best in the industry.
The functional safety versions of IAR Embedded Workbench are certified according to IEC 61508, the international umbrella standard for functional safety, as well as the automotive standard ISO 26262.
Don’t worry about fighting with learning curves, issues or bugs on your own. With support from us, you’re never alone. You get help and guidance when you need it and can stay focused on your project.
Outstanding speed optimizations enable IAR Embedded Workbench to generate very fast performing code. With the shortest possible execution times it is the ultimate choice for developing low-power applications.
Recent top scores achieved using IAR Embedded Workbench:
EEMBC is a non-profit industry association for embedded microprocessor benchmarks. EEMBC CoreMark is a simple, yet sophisticated, benchmark that is designed specifically to test the functionality of a processor core. Running CoreMark produces a single-number score allowing users to make quick comparisons between processors.

The multicore implementation has been redesigned. It is now easier to setup and configure multicore debug sessions. The debugger can now more easily cope with startup and sleep scenarios where cores are inactive.
You can now select secure or non-secure setup in the project options. In previous releases this had to be done using Extra Options.
The CMSIS-Pack implementation is now based on the CMSIS-Pack Eclipse plugin from Arm.
The language support now adds extended support for the Arm ACLE (Arm Compiler Language Extensions)
The compiler adds support for the following C++17 features:
C-SPY can now display digital state information from the device in the Timeline window and the State Log window for the Texas Instruments devices CC1350, CC2650, CC2640R2F and the CC13x2/CC26x2 device family.
Support for new devices from Cypress, Mindmotion, NXP, Silicon Labs, STMicroelectronics and Toshiba.
Support for MSP430FR2355, MSP430FR2353, MSP430FR2155, and MSP430FR2153 has been added.
Configurable FRAM Write Protection settings have been added to the IDE for the new devices.
Updated device support files, new version 1.205 of the device support and new version 3.13.0.1 of the msp430.dll.
It is now possible to log the debug communication towards the msp430.dll.
For MSP430F5xx/6xx devices, you can now set a custom password.
A new text editor and source browser are introduced in this version. The new features include auto completion, parameter hint, code folding, block select, block indent, bracket matching, zoom and word/paragraph navigation. The new source browser adds features like Go to Declaration and Find All References to symbols.
The new LMS used with this release introduces new features like commuter licenses, automatic license activation and support for virtual servers.
It is now possible to specify variables for which you want to collect data samples. You can view the sampled data either in table format in the Data Sample window or as graphs in the Sampled Graphs window.
It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.
A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.
The new Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. The return value from the evaluated macro or expression is shown in a separate column and the user can re-trigger the evaluation at any given point.
The version control integration has been extended with support for Subversion (SVN).
Updated the MISRA C 2004 package with 19 new checks.
Nuvoton Nu-Link support is now integrated into IAR Embedded Workbench for 8051.
A new plugin for Segger embOS, version V8.10.3.0, has been added.
Nuvoton N76E device family: N76E885 has been added. N76E003 and N76E616 have been updated.
General improvements of the IDE startup time and overall performance. Further performance improvements will be implemented in the next release in Q2 2018.
Now with full control of the execution at the task level and enabling display of the local execution context for each individual task.
CMSIS version 5.3 adds the CMSIS NN software library, a collection of efficient neural network kernels developed to maximize the performance and minimize the memory footprint of neural networks on Cortex-M processor cores.
ST-LINK debug driver support for ST-LINK Shared mode using a TCP server.
Nuvoton Nu-Link debug probe support is now integrated into the IAR Embedded Workbench for Arm installation.
A project converter is now available to ease porting Atollic TrueSTUDIO projects to IAR Embedded Workbench for Arm.
Support for MSP430FR2422, MSP430FR2512 and MSP430FR2522 have been added.
Updated device support files and new version 3.11.0.1 of the msp430.dll.
The Compiler Reference Guide has been updated.
Updated MISRA C:2004 package with 19 new checks.
Added device support for DS4830A, DS4834 and DS4835.
The C-SPY OWL hardware debugger driver has been updated.
Updated IAR XLINK Linker and library tools.
This release provides basic supports for the Arm v8-R/Cortex-R52 architecture.
The IAR C/C++ compiler for Arm now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.
The Fault exception viewer is a new debugger window that provides useful information about the cause of a fault exception. It lists the peripheral registers in the System Control Block (SCB) that control fault exceptions and provide information of their cause. All Cortex-M processors have a fault exception mechanism included and is therefore supported by this new feature.
The MISRA C:2004 package in C-STAT has been updated with about 20 new checks, of which some are enabled by default.
The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.
The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.
C-SPY now supports the Renesas E2 on-chip debugging emulator.
The start/stop function available for the OCD emulators makes it possible to execute specified routines of the user application immediately before starting and immediately after halting program execution.
The Timeline and Event log windows in C-SPY now supports RL78 devices with a built-in analog front-end for sensor applications.
