A 3D GRAPHICS LIBRARY FOR 32-BIT MICROPROCESSORS FOR EMBEDDED SYSTEMS

A 3D graphics library for a 32-bit embedded microprocessor which emplo ys neither a floating point unit nor a specific graphics engine has be en developed. The graphics library has been designed to reduce the ren dering time because rendering occupies the major part of the total pro cessing time. Accordingly three proposals, changing the decimal point of coordinate data by targeting the screen size for 1/4 VGA, adopting a suitable multiplication size for the rendering operations and reduci ng the number of divisions, are made in this paper. By adopting these sophisticated techniques, the library achieves 10,000 polygons/sec usi ng only software.
