This paper relates experiences of algorithmic transformations in High Level Synthesis, in the area of acoustic echo cancellation. The processing and memory units are automatically designed for various equivalent LMS algorithms, in the FIR case, with important computational load. The results obtained with different filter lengths, give an accurate prototyping of new fast versions of the LMS algorithm. It also show that a theoretical arithmetic reduction must be correlated to the associated increase of memory requirements
