PHAL-OE_Concept
v5 v6 33 33 Now the question is: would this simple P-HAL be enough to build Software Radio sig-nal processing applications? The answer is yes. Only a short specification of an origin and a destination of a data flow is enough to build any kind of application. Similar to the Turing Machine computing theory, any kind of processing machine based on a sin-gle operation of moving data from one origin to a destination is able to execute any kind of processing task. Thus, porting this concept to signal processing tasks is trivial. 34 34 35 In Figure 3 1, a representation of the abstraction layers involved in P-HAL is drawn. On the top we see the connection graph of the object pieces building the radio application, this is the Abstract Application Layer. On the next level, objects are mapped into real Processing Elements (PE), they physically need a place to be executed or located on (the mapping pattern is not important by now). The P-HAL Layer is the abstraction layer found between the real application processes and the Hardware Layer. An overall P-HAL Platform is represented although three PE (each of them enabling the P-HAL functionalities) are under it.[[ PHALOE.gif]]35 In Figure 3 1, a representation of the abstraction layers involved in P-HAL is drawn.
