ThreadX-Lite RTOS is a new, single-user license that targets the ARM Cortex-M series microcontrollers. The ThreadX-Lite real-time operating system is a subset of ThreadX RTOS and contains many ThreadX features and capabilities. ThreadX-Lite is packaged in a compact object library designed with IAR Systems for use with the IAR Embedded Workbench IDE. The Express Logic ThreadX-Lite is available exclusively through IAR Systems for $4,500 per seat, with no run-time royalties.
IAR Systems introduced version 5.41 of the IAR Embedded Workbench for ARM. The latest version is highly optimized for code size and increased execution speed. The IAR Embedded Workbench version 5.41 performs up to 13% better on CoreMark benchmarks for Cortex-M0 compared to the previous version of IAR Embedded Workbench. IAR Embedded Workbench is compatible with other ARM EABI compliant compilers and over twelve ARM cores.
