Abstract
This thesis presents a simulation environment developed for the fast prototyping and evaluation of complex systems using hardware-software co-simulation. A system is represented as a set of concurrent processes communicating with each other by message passing, which provides a natural abstraction for the modeling of large real-time systems such as a speech recognition system or a distributed computer network. Hardware implementation and software simulation models are handled identically so that they can be freely intermixed together for the simulation at system level. Existing hardware board can be directly used as a simulation model, or a fast programmable DSP board can be interconnected to software simulation as a simulation accelerator. The software simulation can be incrementally transformed into physical implementation during the design process. The co-simulation environment has been developed within Ptolemy framework which is capable of supporting multiple models simultaneously for design specification. Consequently, each process model can be further refined into a data flow model or an event-driven model. A customized multi-tasking kernel has been implemented as the simulation engine for concurrent processes using SUN’s Light Weight Process(LWP) library. Lastly the implementation of cosimulation based on a target hardware is described.
