We address the process of designing software defined radios. Our goal is to design radio functions once and use automated tools to transform the design to implementations on different platforms. ReTarget is an approach and a process that (1) describes radio functions in a specification language, Rosetta, (2) translates specifications to an intermediate language suitable for hardware and software implementation, and (3) translates the intermediate language to VHDL and C programs. In this feasibility study, we demonstrated specifying radio functions in a high level language, translation to an intermediate language, and further translation to an implementation language. A number of issues arose during the study. Specifically, (1) what mechanisms, that are compatible with both hardware and software implementation, should be used to exchange information between radio functions and (2) how to set up control and management of radio function in this primarily data-flow oriented domain. |
