چکیده
Trigonometric functions have wide variety of applications in real life. Specially SIN and COSINE waves have been very useful in medical science, signal processing, geology, electronic communication, thermal analysis and many more. Real life application requires fast calculation capabilities as much as possible. Hardware, due to its hardwired design, provides high speed calculations for such application. This paper presents a hardware design that calculates SIN and COSINE value of a given angle using COordinate Rotation DIgital Computer (CORDIC) algorithm.
