摘要
現代嵌入式系統應用範圍廣泛，信號處理功能的變化非常大。因此，嵌入式系統的設計困難度是與日俱增。通常，許多現代的嵌入式系統是各種異質的子系統 — 可程式數位信號理器(PDSP)、記憶體、可程式邏輯裝置(PLD)及特殊應用積體電路(ASIC)等 -- 組成，以便克服日趨複雜的設計問題。如何做好嵌入式系統在系統設計上的規劃，降低系統建構的複雜性，提升系統中各個單元的效能，增加系統中軟體、硬體元件的再利用性及縮短系統的開發時間，變成是一個非常重要的課題。
為了解決上述種種的問題，本論文設計一個整合DSP、FPGA、ASIC的嵌入式應用發展平台，提供系統開發者快速發展、驗證自行發展的嵌入式原形(Prototype)應用。在系統規劃方面，提出以物件導向系統分析法與統一塑模語言作為系統分析及規劃的方法與工具，將系統中所包含的軟體單元與硬體單元，均視為獨立的元件，配合所提出的平台，設計統一的元件介面，作為系統中各單元的通訊依據。將軟體與硬體均視為各自獨立的IP，如此可提高各單元的再利用率，增加系統的穩定性，使得系統的維護更加的容易。為了證明所提出平台架構的正確性，我們以設計軟體IP與硬體IP的方式，並配合物件導向系統分析方法，設計模擬一個倒單擺模糊控制系統。經實驗結果顯示，本研究所提方法確實可行。

Abstract
Modern embedded systems can be utilized in widespread applications, and the type of the signal processing functions varies enormously. Therefore, the difficulties of designing an embedded system are growing substantially. In general, Many modern embedded systems are composed of several heterogeneous subsystems, including programmable digital signal processor (PDSP), memory, programmable logic device (PLD), and application specify integrated circuit (ASIC), etc., to overcome the developing problem of great complexity. heterogeneous units compose such a system, and are in responsible for processing the signal originated from different sorts. Therefore, it becomes more complicated to carry out the architecture design of modern embedded system. The followings will be critical issues, drawing up the structure design of an embedded system, lowering down the complexity of system constitution, raising the efficacy of every unit in the system, increasing the recycling of units in the system no matter hardware or software, and shortening the development cycle.
In order to resolve the problems describing above, this paper proposes an embedded development platform integrating with DSP, FPGA, and ASIC. On the basis of the platform, a system developer can complete the design rapidly and identify the prototype. In the aspect of system scheme, Object-Oriented System Analysis and Unified Modeling Language (UML) are utilized to proceeding the system analysis and plan. We treat the hardware and software units belonging to the system as independent components, and design a uniform interface to communicate each unit in the system. To treat each unit no matter hardware or software as independent IP (Intellectual Property) will increase the reusability of every component, make the system more stable, and maintain it more easily. Through Objected-Oriented System Analysis and independent hardware and software IP, we design and simulate an inverted pendulum fuzzy control system to verify the accuracy of the system architecture mentioned above. The experimental result reveals our methodology is realizable and practical.
