 The ALOE concept tries to address the main issues related with the Software Radio technology. It assumes the need of supporting, partial or total, reconfiguration of the radio processing chain, the need to deploy the radio application onto a heterogeneous hardware platform capable to assume the high computing requirements of modern wireless systems, the need to assure strong real-time execution constraints, the need to easily develop and integrate software modules and the possibility to execute them in different types of processors assuming an easy portability.

 Previous figure tries to illustrate the PHAL-OE concept. On the bottom we can see the Hardware Layer where we can found several processors or Processing Elements (PE) physically interconnected among them. On top of the figure we can see the Abstract Application Layer where a graph of a radio application tries to define the required tasks (objects) and the data flow among them. In the Real Application Layer we can see the previous tasks but using the services or functionalities provided by PHAL-OE to build coherently the radio application. On th PHAL-OE Layer we observe that from the point of view of the tasks (objects) conforming the radio application all them only see the same platform, the PHAL-OE Platform, not being aware of any detail related with the hardware. On such layer, but from the hardware point of view, we can find the specific implementation of the PHAL-OE functions for each one of the processors used to build the entire Hardware Layer.
