Cosmic 68300/68K Cross Development Tools

Cosmic's toolchain for the 68k/68300 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 Freescale 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 68300 and 68000 family of processors. IDEA is designed specifically for developing embedded applications with Cosmic compilers. IDEA integrates an editor, project manager, graphical smart buil /make facility, program analyzer, link file generator, documentation manager and ZAP debugger into one easy to use environment running under Windows 2000 and XP.

Third Party IDE Integration

Most Cosmic compilers can be easily integrated in third party IDEs such as Borland Codewright and RistanCase Development Assistant for C. Click here for more information.


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.

68300/68K specific features include:
  • 68300/68K Family

  • The Cosmic 68300/68K compiler generates highly efficient code for the 68300 (CPU32 and CPU32+) and 68000/68302 family of processors.
  • ANSI and ISO C Compiler

  • The Cosmic 68300/68K compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the 68300/68K processor cores.
  • Reentrant and Recursive

  • All code is fully reentrant and recursive using standard ANSI stack frame conventions.
  • Byte EEPROM Support

  • Compiler provides transparent support for on-chip EEPROM (library source included). Allocate any C data object(s) to the EEPROM and the compiler takes care of the formatting and programming.
  • In-line Assembly

  • The compiler provides three convenient methods for adding assembly code inside a C program. Includes an argument passing mechanism.
  • IEEE-754 Floating Point

  • Supports IEEE 32 bit single and 64 bit double precision floating point formats with full ANSI libraries (Source code included).
  • Absolute Listings

  • Optionally produce relocatable and/or absolute C interspersed with the corresponding Assembly listings.
  • 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 PC, SUN and HP to share objects for linking and debugging.
  • IEEE-695 and ELF/DWARF Debug Support

  • The Cosmic compiler suite supports the IEEE and ELF DWARF standard debug formats used by many popular emulators and logic analyzers.
  • In-Circuit Emulator Compatibility

  • Cosmic's 68300/68K compiler is compatible with emulators and BDM debuggers from Hitex, I-Systems, Lauterbach and NOHAU.
  • 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!!
  • OS Compatibility

  • Cosmic 68300/68K compiler is compatible with most 68300/68K operating systems and real-time kernels including specific ports from CMX and MicroC/OS-II.

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 68300. (1) ZAP SIM Debugger with included processor Simulator, (2) ZAP BDM debugger - uses the 68300's on-chip background debug mode.

ZAP 63000 BDM specific features include:

  • Real-time debugging

  • ZAP 68300 BDM provides a low cost real-time target debugging environment using the on-chip Background Debug Mode protocol.
  • Multiple Execution Modes

  • ZAP BDM offers 2 execution modes
    BGND mode - ZAP will uses a BGND instruction swap for standard breakpoints. This allows an unlimited number of breakpoints when debugging from RAM.
    ISTEP mode - This mode uses the BDM instruction step to execute between breakpoints.
