Discrete Cosine Transformations (DCT) and inverse DCT (IDCT) functions fast. The latter are a must for fast execution of the algorithms for signal analyzing, coding, filtering, noise cancellation, echo-elimination, compressing and decompressing, etc. Figure 2.6 shows the block diagram for a digital signal processor
