Cosmic ColdFire V1 Cross Development Tools

NXP™ and the NXP logo are trademarks of NXP Semiconductor, Inc. All other product or service names are the property of their respective owners. ©NXP Semiconductor, Inc. 2004
Cosmic's tool chain for the ColdFire V1 family is part of a complete and uniform product line incorporating over 20 years of innovative design and development. Cosmic's familiar and easy to use software interface is available for all NXP microcontrollers to simplify the migration between targets. All Cosmic products include one year of technical support and updates.

Integrated Development Environment

All Cosmic C Cross Compilers for Windows include IDEA - Cosmic's own integrated development environment which is preconfigured for the ColdFire 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 under all popular Windows versions.
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.

ColdFire specific features include:

  • Designed for Performace
    The Cosmic Coldfire compiler has been designed to produce efficent code. This avoids the complexity and overhead of a more generic compiler and results in excellent performance.
  • ANSI and ISO C Compiler
    The Cosmic Coldfire compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the Coldfire V1 processor core. All Coldfire V1 derivatives and sub-families are supported including MCF51AC, MCF51AG, MCF51CN, MCF51EM, MCF51JE, MCF51JM, MCF51MM and MCF51QE.
  • Reentrant and Recursive
    With all programming models all code is fully reentrant and recursive using standard ANSI stack frame conventions.
  • IEEE-754 Floating Point
    Supports IEEE double and single precision floating point formats with full ANSI libraries (Source code included).
  • ANSI and ISO C Compiler
    The Cosmic ColdFire compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the ColdFire processor cores.
  • Moveable Code Feature
    Moveable code feature is designed to make RAM based code like boot loaders 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 locate and copy the moveable code into RAM at any time for execution.
  • Host Independent Formats
    The Cosmic relocatable and absolute object formats are host independent. This allows user's on PC, SUN and HP to share objects for linking and debugging.
  • 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.
  • Automated Check Sums
    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.
  • ELF/DWARF Debug Support
    The Cosmic compiler suite supports the ELF/DWARF standard debug format used by many popular emulators and logic analyzers.
  • Eclipse compatible
    Supports default Eclipse error parser format
  • In-Circuit Emulator Compatibility
    CXCF is compatible with all existing emulators.
  • 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!!
ZAP Debugger

Cosmic's ZAP debugger is a full featured C and Assembly language source-level debugger for embedded applications. ZAP's intuitive graphical interface is uniform for all targets and execution environments. ZAP is available in 2 execution versions for the ColdFire. (1) ZAP SIM Debugger with included processor Simulator, (2) ZAP BDM debugger/flash programmer uses the ColdFire on-chip background debug mode.

ZAP ColdFire BDM specific features include:

  • BDM Interface Cables
    ZAP BDM supports Background Debug Mode cables from P&E Microcomputer Systems.
  • Real-time debugging
    ZAP ColdFire BDM provides a low cost real-time target debugging environment using the on-chip Background Debug Mode protocol and hardware breakpoint module. ZAP Programs and debugs single chip applications directly in Flash in real-time. No remapping or reprogramming required.
  • Hardware Breakpoint
    ZAP fully utilizes the on-chip hardware breakpoint module to provide real-time execution and data breakpoint capabilities. ZAP transparently configures the hardware breakpoint module to supports real-time execution breakpoints.
