Abstract: A transducer for transforming a set of syntactic and sampled data from a general purpose system to control a special purpose system. The transducer includes a first and a second transducer modules. The first transducer module is coupled to the general purpose system for receiving the syntactic and sampled data from the general purpose system, and to transform the received data into a different set of syntactic and sampled data. The second transducer module is coupled to the first transducer module for receiving the syntactic and sampled data generated by the first transducer module, and transforming the received data into another set of syntactic and sample data that are different from the other two sets of syntactic and sampled data to control the special purpose system.
