ABSTRACT
<p>The use of the 16-bit ADSP-2100 digital signal microprocessor as a fixed-point, low-end graphics engine for applications such as video games and small computer graphics packages is examined. It serves as the basis for a complete, hardware-oriented approach to performing graphics operations on a 3-D database. Normalization and formatting are performed to avoid overflow and preserve data formats through the transformation operation. Data structures that facilitate object rendering through the Bresenham line-segment drawing algorithm are used. A 3*3 rotation matrix is derived for this application, and the means for implementing translation, scaling, perspective, and zooming are described.</p>
