The starting aim of this project is to give more flexibility to the 4th mobile generation systems. Since reconfigurable-reprogrammable systems are becoming each time more widespread in the communications system implementations, it is set out to analyze those mechanisms of the current processor devices (DSPs) that have high importance when flexibility has to be provided to the system management. This way, the ALOE middleware - used in Software Radio - is ported from its original x86 computer running Linux to the DSP processors from Texas Instruments. Meanwhile, the Ethernet interface that the DSP provides is evaluated with the objective of its characterization in real time environments.
