Cosmic ARM/Cortex "M" Cross Development Tools

Cosmic's toolchain for the Cortex-M family (M0, M0+, M3, M4 and M7) is part of a complete and uniform product line incorporating over 25 years of innovative design and development. All Cosmic products include one year of technical support and updates.

The Cosmic ARM Cortex-M compiler supports the ARM CMSIS (Cortex Microcontroller Software Interface Standard) hardware abstraction layer, DSP libraries and RTX operating system. You can download the CMSIS distribution from the links below. These distributions include Cosmic ports and examples in addition to the standard ARM distribution. Please constact your nearest Cosmic Software office or distributor for a compatible tool suite evaluation.

Integrated Development Environment

All Cosmic C Cross Compilers for Windows include IDEA - Cosmic's own integrated development environment which is preconfigured for the Cortex family of processors. IDEA is designed specifically for developing embedded applications with Cosmic compilers. IDEA integrates an editor, project manager, graphical smart build/make facility, program analyzer, link file generator, documentation manager and ZAP debugger into one easy to use environment running on any Windows system.
Click here for more information about IDEA.


The C Compiler package includes: an integrated development environment with optimizing ANSI-C cross compiler, macro assembler, linker, librarian, hex file generator, object format converters, debugging support utilities, run-time library source code, and a multi-pass compiler command driver. The compiler also supports non-intrusive C source-level debugging with Cosmic's line of ZAP debuggers.

Cortex Specific features include:
  • Designed for ARM Cortex M code
    The Cosmic Cortex M compiler has been designed to produce efficent code optimized for the Cortex M instruction set. This avoids the complexity and overhead of a more generic ARM compiler and results in excellent performance.
  • ARM CMSIS Compatible
    The Cosmic Cortex compiler is compatible with ARM Cortex Microcontroller Software Interface Standard (CMSIS).
  • ANSI and ISO C Compiler
    The Cosmic Cortex compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the Cortex processor core. All Cortex derivatives and sub-families are supported.
  • Reentrant and Recursive
    With all programming models all code is fully reentrant and recursive using standard ANSI stack frame conventions.
  • Memory Models
    CXCortex supports different programming model options to fine tune code optimizations to your application and memory requirements.
  • C Support for Short Data and Costants
    Compiler source extensions provide efficient use for frequently used data and constants.
  • In-line Assembly
    The compiler provides three convenient methods for adding assembly code inside a C program. Includes an argument passing mechanism.
  • Absolute Listings
    Optionally produce relocatable and/or absolute C interspersed with the corresponding Assembly listings.
  • IEEE-754 Floating Point
    Supports IEEE single and double precision floating point formats with full ANSI libraries (Source code included, royalty free).
  • Moveable Code Feature
    Moveable code feature is designed to make RAM based code like boot loaders and programmers easy to create and maintain. The Linker automatically creates a segment in ROM to store moveable code. Then at run time, use the supplied library function to relocate and copy the moveable code into RAM for execution.
  • Check Sum Feature
    Easy to use check sum facility and library (Source included) allow users to quickly implement an efficient check sum on any or all sections. Check sum calculation and insertion is transparently managed by the linker.
  • Mixed C and Assembly
    Cosmic tools support mixed C and Assembly applications. Including Assembler support for C #defines and #includes so C and assembly language modules may share common constants and macros.
  • Host Independent Formats
    The Cosmic relocatable and absolute object formats are host independent. This allows user's on Windows and Linux to share objects for linking and debugging.
  • ELF/DWARF Debug Support
    The Cosmic compiler suite supports the ELF DWARF 2.0 standard debug formats used by many popular emulators and logic analyzers.
  • Flexible Compiler Interface
    Cosmic compilers are designed to be powerful and flexible so they can be used with virtually any environment. Use Cosmic's own IDEA interface or use your favorite editor, make utility and/or source code control system - It's Your Choice!!
