The Discrete Cosine Transform (DCT) is one of the basie varieties of transform 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. FPGA structures. Authors implemented DCT transform used Chen algorithm and Lee algorithm, because these algorithms most effective for FPGA irnplementation. Paper presents implementations results in Xilinx chips XCV200BG352.
