博士 === 國立臺灣大學 === 電機工程學系研究所 === 84 === The system-level design automation of parallel computer systems is presented in this Dissertation. The successful application of object-oriented techniques in all the three system design phases, i.e., in phases of modeling, synthesis, and simulation, is demonstrated. For modeling, a Class Hierarchy is constructed with each class representing some system part. This Class Hierarchy not only acts as an object repository but also plays the role of a synthesis guide since object-oriented operators, which traverse the hierarchy, are directly used in the synthesis process. For synthesis, two methodologies are proposed and implemented: Performance Synthesis Methodology (PSM) and Object-Oriented Concurrent Synthesis Methodology (OOCSM). PSM is a performance-oriented multi-level synthesis approach to multiprocessor system design, while OOCSM enhances this synthesis methodology by incorporating machine learning, fuzzy logic, and concurrent synthesis into the design process, thus shortening the total design time and making the design process more efficient. For simulation, a Modularized Reconfigurable Simulator is used to efficiently simulate design alternatives and evaluate their performance. Besides the above technical work, a Petri-net based system-level concurrent synthesis model, Multi-token Object-oriented Bi-directional net (MOBnet) de model, is presented to analyze the synthesis process. This model is proved to be a valid synthesis model and its use in design completion check and synthesis rollback is also discussed. Finally, an integrated environment, called Multi-level Intelligent Synthesis and Simulation Environment (MISSE), is proposed for the complete design of a system starting from modeling to the final simulation.
