Hardware Support

This page lists the processor architectures for which a port is maintained in the ThreadX source tree, together with the toolchains each port currently supports. The list is derived directly from the contents of the ports/ and ports_smp/ directories of the ThreadX repository, and is therefore authoritative for the current release.

Ports are grouped by architecture family. Single-core ports are covered first, followed by the SMP ports. Simulation ports, used for development and testing on a host PC, are listed at the end.

Notes

The information above reflects the state of the ThreadX repository at the time of writing. The authoritative source is always the set of directories under ports/ and ports_smp/ in the ThreadX source tree.
Toolchain abbreviations: AC5 and AC6 refer to ARM Compiler 5 and 6, GHS to Green Hills Software, GNU to the GNU toolchain (GCC/Binutils), IAR to the IAR C/C Compiler, *Keil* to the Keil MDK toolchain, *CCS* to Texas Instruments Code Composer Studio, *CC-RX* to the Renesas CC-RX compiler, *MetaWare* to the Synopsys MetaWare toolchain, *XCC* to the Cadence Xtensa C/C Compiler, and Clang to the LLVM/Clang toolchain.
Historical ports for architectures no longer present in this repository (for example Analog Devices SHARC/Blackfin, Infineon TriCore, Microchip PIC/SAM, Renesas SH/V850, Intel x86/NIOS II, Xilinx MicroBlaze/PowerPC) may be available in archived branches or from the original Express Logic distribution, but are not maintained as part of the current Eclipse ThreadX source tree.
