隨著無線網路和行動計算的普及，近年來無線多媒體已經成為重要的產業發展趨勢之一。基於此一技術的品開發通常具有幾個特性:系統複雜度高、產品生命週期短、，技術與經驗難以有效累積。特別針對高速無線多媒體應用，由於缺乏具彈性的雛型化系統開發與驗證平台、導致產品研發不確定性增加以及上市時間延宕。本研究因此提出了一個高效能無線多媒體嵌入式系統開發平台，並結合MIAT嵌入式硬體設計方法論，提供系統快速雛型化和驗證。
硬體平台包含三個子模組：大容量FPGA核心板、高取樣率的A/D、D/A轉換板、以及5 GHz射頻電路模組板。透過本平台，開發者得以實現更寬的通道頻寬、更多的串流、以及更強的MIMO技術，讓多媒體資料傳輸速度大幅提升。此外我們還整合了gigabit乙太網路和5M像素的攝影機週邊模組來展示應用系統雛型開發的架構。
我們採用MIAT嵌入式硬體設計方法論進行基於此一平台的雛型系統開發。我們利用IDEF0工具來做階層式和模組化的分析，針對每一模組，使用GRAFCET工具進行離散事件的行為建模，最後將其合成為硬體電路，接著就可以在硬體平台上做實體電路的驗證。
結合了硬體平台和設計方法論，將使得高效能無線多媒體系統的開發更為快速可靠，採用MIAT方法論則使得設計流程變得清晰並具有可驗證性，而個別模組的設計概念與方法得以有效保留並再使用，對於複雜度越來越高、產品生命週期越來越短的系統開發問題，提供了一個良好的解決方案。

Due to the increasing popularity of wireless internet and mobile computing, wireless multimedia has become one of the important trends in related industries. Based on the technical & Product aspects of development, there are some significant attributes: systems are often complex, short on product lifespan, techniques and experiences are difficult to accumulate. Especially with high efficient wireless multimedia, the lacking of both flexible prototyping system and validation platform, result in the increasing of uncertainty with the product development, often leads to the delay or abort of the product launch. The Purpose of this research is to propose An embedded system development platform for high efficient wireless multimedia, by combining MIAT Methodology for Embedded Hardware Design, this research will in result, provide a rapid prototyping technology and validation platform.
The hardware platform is assemble by three sub-modules: High Density FPGA Kernel Board, High Sample Rate A/D、D/A Converter Board and a 5 GHz RF Module. By using the proposed platform, developer will be able to utilize wider bend with, more streams, and more powerful MIMO technology, in result of dramatically improvement of speed of the wireless multimedia Transmission. In addition, we also integrated gigabit Ethernet, and 5 megapixel camera peripheral module to demonstrate the infrastructure of the developing system’s prototyping.
We adapted the MIAT Methodology for Embedded Hardware Design to develop our prototyping platform. By utilizing IDEF0(Integration Definition for Function Modeling) to analyze Hierarchical and modular statues, on each and individual modular, after using GRAFCET to model on the Discrete Event, we can synthesize to a FPGA Implementation, and finally we will be able to do a circuit validation test on our proposed platform.
Combine our platform and Design Methodology, will directly result in speeding up and increasing reliability of the development of high efficient wireless multimedia system, adopting MIAT Methodology will result in clear and able to validate the designing process, with our modularize concept, will further provide the feasibility of retain and reuse of one’s designing methods and concepts, our proposed platform provides a fine solution in counter to the problems of rising complexity of the system, with the short product lifespan.
