  1. IDF Framework V0.13 (30th Oct 2001) Rhapsody Generated Code Rhapsody Generated Code External Code External Code OXF Framework RTOS IDF Framework CPU CPU • ObjecteXecution Framework • Interrupt Driven Framework Requires a Real-Time Operating System Needs no Operating System

  2. Current Environments • Environments tested on target hardware • Arm compiler + ARM7 • Environments running on a simulator • Tasking compiler + C166 • Diab compiler + PowerPC 860 • Environments compiling and linking • Keil compiler + C166 • Keil compiler + C51 • Texas Instruments compiler + DSP TMS30C3x/4x • IAR compiler + H8 • CAD-UL compiler + x86 • PanaX compiler + MN10200 • Environments running with an OS (used just to generate a periodic timeout) • Microsoft Visual C++ compiler + Windows • Gnu compiler + VxWorks • Borland compiler + Windows

  3. IDF Characteristics • No need for an RTOS • Can be used with 16 bit compilers • Smaller code size between 5k and 11k (depending on if the list/map/string/collection classes are used) • Avoids using malloc / free (except if containers used) • Entire framework in documented Rhapsody model • Most standard Rhapsody models can be run using the IDF framework (as long as model does not use any OS features, ex: Tasks, Semaphores)

  4. IDF Characteristics • Must create environment for compiler and microprocessor (rough estimate : 1 days work) • Must implement three operations to disable / enable interrupts and setup a periodic interrupt (rough estimate : 1 days work) • Single task / thread • Animated is not supported on the target, this must be done on the host using the OXF framework • IAR & Tasking compiler currently require a perl script to automatically modify the Rhapsody generated code (this problem will be resolved in Rhapsody V4.0) • Currently only Rhapsody in C (Preliminary version does exist in C++)

  5. Generating C166 IDF

  6. C166 IDF + CrossView Simulator

  7. Generating Diab IDF

  8. Diab IDF + SingleStep Simulator

  9. Generating Arm IDF

  10. Arm IDF + AXD Debugger

  11. ARM Stopwatch model Event evPress generated from button ISR Code Size : 20k ! Including Stopwatch code, IDF Framework and C Libraries.

  12. Generating TI IDF for TMS30C3x/4x
