Abstract
We present a solution to a complex multi-tone transient detection problem
to illustrate the integrated use of symbolic and numeric processing
techniques which are supported by well-established underlying models.
Examples of such models include synchronous dataflow for numeric processing
and the blackboard paradigm for symbolic heuristic search.
Our transient detection solution serves to emphasize the importance
of developing system design methods and tools which can support the integrated
use of well-established symbolic and numeric models of computation.
Recently, we incorporated a blackboard-based model of computation
underlying the Integrated Processing and Understanding of Signals (IPUS)
paradigm into a system-level design environment for numeric processing
called Ptolemy. Using the IPUS/Ptolemy environment, we are implementing
our solution to the multi-tone transient detection problem.
