In this tutorial, we wants to illustrate the fact that efficient implementation of the computation part of an algorithm should go further than the simple question “how” the algorithm works and understand “why” the algorithm works. In fact, once the “why” is understood, the algorithm can be modified, either in a lossy of lossless way, in order to be implemented more efficiently. To illustrate this idea, 3 examples are given. The first two examples correspond to a “lossy” implementation (conception of a binary correlator, conception of a parallel turbo-decoder). The last example presents a formalism, named Taylor Expansion Diagram, that allows a lossless transformations of some algorithm specifications.
