An optimized partitioning algorithm for HW/SW codesign is described and applied to the implementation of a digital RAKE receiver for DS-CDMA on an heterogeneous (hardware/software) platform. The development of this partitioning algorithm aims to gather quality features that have already proved effective when applied separately, but had not been used together yet. The partitioning algorithm is applied to a flexible RAKE architecture able to adapt its number of demodulation fingers to each propagation environment. This RAKE detector uses a serial and iterative computation of the required processing in order to jointly optimize performance and computational power
