Abstract: The method of signal compression MMP (Multi-dimensional Multiscale Parser) is based on recurrency of multiscale patterns, where each block of the input signal is approximated by an adaptive dictionary, which is updated with expanded and compressed versions of concatenation of a previously coded block. This algorithm is structured by a binary segmentation tree. This class of algorithms has the characteristics of a high consumption of computational resources. With the advent of techniques and software libraries for the parallelization of applications on CPUs and GPUs, we identified the opportunity to investigate the possibility of acceleration of this class of algorithms.
