博士 === 國立臺灣大學 === 電機工程學研究所 === 88 === The object of this dissertation was to study all aspects concerning the design and implementation of application specific digital signal processor (AS-DSP) system with reconfigurable computing techniques. It aimed to develop a novel state-of-the-art design methodology, as well as the interface reaction models for rapidly prototyping a large design with a small hardware in a low risk. As the incremental complexity of AS-DSP system challenging the traditional design approach, the proposed Modular Partial Prototyping Methodology (MPPM) is considered to be a key feature toward success by preventing the costly design iterations. Based on the divide-and-conquer philosophy, a complicated AS-DSP system is decomposed to the functionality independent modules by its nature. A module is regarded as both a spatial and temporal partition of a design and can be partially prototyped in a reconfigurable hardware via the activity of interface reaction models. A PC-based Programmable And Reconfigurable Transmogrifier (PART) FPGA card is supported for the embedded hardware. While directing a design with C program, it is efficient to evaluate an individual module by imposing the strategy of object movement from software to hardware. The study concerned not only with AS-DSP system-on-chip (SoC) design but also with cooperations of combing off-the-shelf components. Four study cases including the developing of a general purpose embedded DSP system, the design of dedicated DSP processor for digital wheelchair controller, the realization of an I-phone system, and the implementation of block matching algorithm (BMA) for motion estimation in MPEG2 encoder are demonstrated. The results disclosed that the dynamic nature of AS-DSP system is easy to be captured with reconfigurable features. It is hoped that the study can lead a designer faces upcoming challenge with a new thought of design in a short cycle rather than design in a low cost while without sacrificing the design quality.
