Cosmic S12Z Cross Development Tools

Cosmic's tool chain for the S12Z 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 S12Z 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.

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.

S12Z specific features include:

  • S12Z core designed for C language efficiency

  • Cosmic worked closely with NXP S12Z core designers to optimize the S12Z instruction set for the C language to ensure better code density and performance than its predecessors even with expansion of the linear address space to allow larger programs.
    The Cosmic compiler has been used during S12Z development and validation, so you can be sure it is a perfect fit for all s12z projects.
  • S12Z Processor Core

  • The Cosmic S12Z compiler generates highly efficient code for the NXP S12Z family of microcontrollers including S12ZVM and S12ZVH MagniV derivatives and compatibles. (more info on derivative support here)
  • Linear Addressing Space

  • Full support for 16MB linear address space with only one code segment needed. No need for any bank switching.
  • Improved code density and performance

  • The goal of the S1Z project was to produce an enhanced instruction set that supported 16MB of code space without bank switching, but still produce a code density at least as good as the current S12 and S12X cores. The Cosmic S12Z compiler takes full advantage of the new core and provides consistently smaller and faster applications compared to the S12 and S12X.
  • Use of MAC instructions directly in C

  • The compiler directly generates Multiply And Accumulate instructions from standard C code.
  • Fractional Math Instruction Support (Fixed Point)

  • The compiler uses the new S12Z Fractional math instructions to support efficient fixed point math using ISO defined C level Fixed Point data types: short _Frac (16 bit) and long _Frac (32 bit) types. Includes fast Fixed point libraries.
  • Fast Float Operations

  • Compiler and libraries use the fractional math instructions for efficient Float operations
  • 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 S12Z compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the S12Z 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.
  • Position Independent Code and Data

  • Compiler and libraries provide options to generate position independent code and data which is useful for moveable code such as boot loaders and flash programmers.
  • 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.
  • 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
  • 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 S12Z. (1) ZAP SIM Debugger with included processor Simulator, (2) ZAP BDM debugger/flash programmer uses the S12Z on-chip background debug mode.

ZAP S12Z BDM specific features include:

  • BDM Interface Cables and OSBDM

  • ZAP BDM supports Background Debug Mode cables from P&E Microcomputer Systems and direct connect to NXP boards using OSBM..
  • Automatic BDM Firmware Updates

  • ZAP will automatically update firmware in BDM and Multilink cables and OSBM firmaware on boards (in boot loader mode).
  • Real-time debugging

  • ZAP S12Z 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.
