Abstract
A 32 bit floating-point one-dimensional discrete cosine transform unit was designed based on the Vetterli and Ligtenberg fast DCT flow-graph using Mentor Graphics´ and Synopsys´ tools. The floating-point algorithm and the VHDL code of the DCT unit is described, and the simulation results of the output are presented.
