Prototypage Rapide et Génération de Code pour DSP Multi-Coeurs Appliqués à la Couche Physique des Stations de Base 3GPP LTE

摘要

The 3GPP Long Term Evolution (LTE) is a new terrestrial telecommunication standard which base stations, named eNodeB, necessitate much power to process the data transmitted and received by the LTE antennas. Digital Signal Processors (DSP) are commonly employed to compute physical layer algorithms in base stations. Modern DSPs are highly complex and heterogeneous systems. No ideal solution has been found to automatically assign application parts over the multiple cores contained in an eNodeB. In this thesis, we design a rapid prototyping and code generation framework that assists programmers of multi-core DSPs by automating the most complex design phases. As some algorithms of the LTE physical layer are too variable for static assignment, we present a simple adaptive scheduler that computes real-time assignment choices based on predicted execution times.
