Abstract
The Discrete Cosine Transform (DCT) is one of the basic varieties of qtransform coding algorithms. Moreover DCT is used in standard algorithms of compression of still image (JPEG) and video compression of algorithms (MPEG, H.26x). In case of discrete cosine transform of compression's images of algorithms there are used the blocs: 8x8 pixels. Paper presents problems connected with implementation of DCT algorithms in reconfigurable FPGA structures. Authors implemented DCT transform used Chen's algorithm and Loeffler's algorithm, because these algorithms most effective for FPGA implementation. Paper presents implementations results in Xilinx chips XCV200BG352.
