碩士 === 國立交通大學 === 電子工程系 === 88 === This thesis investigates an effective approach to the system-level design of multimedia signal processing applications. To design these systems, we use the hardware/software codesign approach, which allows the hardware and software designs to be tightly coupled throughout the design process. Given a specification of system functionality and constraints, we propose a model to describe the system. After the model has been analyzed, partitioning is used to determine the parts of the system functionality that are delegated to application-specific hardware and the software that runs on the processor. Based on the result of hardware/software partitioning, we determine the optimal implementation of a system. We also explore issues concerning system synchronization and the implementation of hardware/software interface to accommodate communications between various parts of the system. This hardware and software codesign approach proposed makes it possible to build a time-constrained signal processing system on a chip using programmable parts and application-specific units. We use a media processor design as an example. The verification method and simulation results are also given in this thesis.
