Integrated Development Environment

All Cosmic C Cross Compilers for Windows include IDEA - Cosmic's own integrated development environment which is preconfigured for the RX 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.

Compiler

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.

RX specific features include:

• Support of all RX variants
  All RX subfamilies, including RX100, RX200 and RX600 are supported.
  
• Floating Processor Unit
  The RX600 Floating Point Unit is fully supported in Standard C.
• ANSI and ISO C Compiler
  The Cosmic RX compiler follows ANSI and ISO rules and conventions. All code and libraries are optimized specifically for the RX processor cores.
• Moveable Code Feature
  Moveable code feature is designed to make RAM based code like bootloaders 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.
• 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 single and double precision floating point formats with full ANSI libraries (Source code included, royalty free).
• 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 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!!

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 RX. (1) ZAP SIM Debugger with included processor Simulator, (2) ZAP debugger/flash programmer for the SEGGER J-Link probe.
