System canvas: a new design environment for embedded DSP and telecommunication systems

We present a new design environment, called System Canvas, targeted at DSP and telecommunication system designs. Our environment uses an easy-to-use block-diagram syntax to specify systems y high level of abstraction. The block diagram syntax is based on formal semantics, and uses a number of different models of computation including cyclo-static dataflow, dynamic dataflow, and a discrete-event model. A key feature of our tool is that the user does not need to have an awareness of which model is being used; the models can be freely mixed and matched and a simulation can consist of an arbitrary combination of models. The blocks are written in `C' or `C++' and it is straightforward to write custom blocks and incorporate them into custom libraries. Other key features include the ability to control simulations via languageneutral scripts, and a powerful optimization engine that enables optimization of the system over arbitrarily specified parameters, constraints, and cost functi...
