Why choose IAR Embedded Workbench?
Why do we choose to pay for IAR Systems development tools instead of using various free development tools? There are several key reasons:
1. IAR Embedded Workbench generates space-efficient and reliable executable code.
After extensive testing, IAR Systems' C/C++ compiler consistently produces efficient and reliable code, especially for larger applications. The system uses both global and chip-specific optimization techniques. The range detection provided by the connector plays a critical role in ensuring high-quality code generation. With the latest technology architecture, IAR Embedded Workbench 4.10B for AVR reduces code size by up to 10% compared to version 3.20A, outperforming other compilers. This allows developers to use smaller, lower-cost processors, reducing overall product development costs.
2. Code size directly impacts product cost.
Smaller code means more efficient use of memory, which translates into lower hardware costs. For example, if a company produces 10,000 devices and each device saves $2 due to a smaller processor, that’s a significant financial benefit. While design teams may not prioritize cost, it’s often the top concern for product or sales managers.
3. Flexibility for future expansion.
Compact code leaves room for additional features without requiring a new chip. If a customer wants to add functionality later, IAR's efficient compiler and code analysis tools can help meet deadlines without redesigning the entire system.
4. Reliable and stable development environment.
Developers need tools they can trust. IAR Embedded Workbench integrates seamlessly with Atmel ICE 2000 and JTAG ICE, minimizing communication issues and allowing developers to focus on their projects without tool-related interruptions.
5. Integrated workflow for seamless development.
The platform includes everything from code editors to debuggers, all tightly integrated. This makes it easy for developers to work within a single environment, improving efficiency and reducing complexity.
6. Quick path from concept to implementation.
IAR provides visualSTATE and MakeApp tools that automate code generation and driver creation, helping developers save time while maintaining high code quality.
7. Global support and services.
IAR Systems offers comprehensive technical support worldwide. Large companies can also benefit from VIP programs and global collaboration plans.
8. Strong commitment to AVR.
IAR Embedded Workbench for AVR includes advanced features like JTAGICE mkII debugging, C++ templates, MISRA C compliance, and more. Future releases will bring even more enhancements.
9. Close collaboration with Atmel.
The AVR microcontroller family was developed in partnership with IAR Systems. This ensures full utilization of C language capabilities and deep integration between hardware and software.
