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. |
