Many algorithms are used in JPEG standard for compression of still images, but the most demanding one is the DCT. The fast discrete cosine transform is the basic transform which occur in most coding algorithms. In the case of images it is performed on 8×8 pixel blocks. Paper presents comparison of IDCT algorithms concentrated on amount of arithmetic operations, multiplications, and number of pipelined steps. Results are achieved by implementing each one in programmable device FPGA (xc6vlx240t).
