Abstract

This paper presents a new appoach in the calculation of DCT ( Discrete Cosine Transform) coefficients by using CORDIC algorithm (COordinate Rotation Digital Computer). Hardware processing will be enhanced by applying this algorithm. The computation will be carried out on the real number indicated under 16-bit floating point following the similar presentation as in IEEE 32-bit. The results are simulated in the VHDL environment.
