Embedded Workbench for ARM - EWARM

Integrated development environment and optimizing C/C++ compiler for ARM

  IAR Embedded Workbench with its optimizing C/C++ compileris an integrated development environment for building and debugging ARM-based embedded applications. It provides extensive support for a wide range of ARM devices, hardware debug systems and RTOSs and generates very compact and efficient code. Ready-made device configuration files, flash loaders and over 1400 example projects are included.

IAR Embedded Workbench is compatible with other ARM EABI compliant compilers and supports the following ARM cores:
  • ARM7E (ARM7EJ-S)
  • ARM9 (ARM9TDMI, ARM920T, ARM922T and ARM940T)
  • ARM9E (ARM926EJ-S, ARM946E-S and ARM966E-S, ARM968E-S)
  • ARM10E (ARM1020E and ARM1022E)
  • ARM11
  • SecurCore (SC100, SC110, SC200, SC210)
  • Cortex-R4
  • Cortex-M0
  • Cortex-M1
  • Cortex-M3
  • XScale
