近幾年來,電腦繪圖已成為人機介面中,最重要的資料顯示方法,並廣泛的運用在各種應用之中。例如計算機輔助設計,醫療方面的影像處理,以及電腦動畫…等等,尤其在3-D 電腦繪圖,3D engine技術的重大突破,使得這些應用可以以低成本的即時3D電腦繪圖技術為基礎。在本篇論文中,我們實作浮點運算CORDIC算術處理器,來執行許多算術運算,並利用這些數學函數的功能來輔助3D engine的設計。
Computer graphics has become one of the important method to display information and has been applied in many applications such as CAD, medical image processing, computer animation, multimedia and virtual reality. These popular applications rely on the low-cost and real-time processing of 3D graphics which become available due to the breakthrough in the hardware design of 3D graphic engine. In this thesis, we implement a CORDIC-based floating-point processor that can compute a wide variety of arithmetic operations and show how it can be applied to the design of 3D engine.
