Complete development toolchain providing one toolbox in one view, giving you one uninterrupted workflow. As a well established frontrunner in the embedded industry, you can rely on IAR Embedded Workbench to compile, analyze and debug your code in the most efficient way.

Highly Optimizing Compiler Technology

IAR Embedded Workbench offers excellent optimization technology to ensure developers that the application fits the required needs and optimizes the utilization of on-board memory and necessary speed.

Broad Device Support

Supporting 32-bit RV32E and RV32I cores, as well as 64-bit RV64I cores. RISC-V extensions such as the C extension (compressed instructions), F and D (32- and 64-bit FPU), M (integer multiplication and division), A (Atomic), and the standardized parts of B (bit manipulation) are also supported, together with the Andes DSP and Performance extensions.

Comprehensive Debugger

The C-SPY Debugger provides extensive debugging capabilities, giving full control of the application in real time. Native debug probe support through I-jet enables high-speed in-circuit debugging and SMP multicore debugging. For livestreaming of trace information for code coverage and profiling purposes, the trace probe I-jet Trace is supported. In addition, a plugin SDK is available for easy integration of emulator interfaces, RTOSs, TCP/IP and network stacks, etc.

Technical Support Included
