| Summary: | 碩士 === 元智大學 === 資訊工程學系 === 89 === In spite of the progression of consuming electronic products for multimedia,the needs of a large amount of audio and vedio data transmission grow explosively.As to the image capture boards on the market so far, most of them merely provide data transmission function.Thus, considering the need of lots of high-resolution multidedia data transmission and the need of real-time image processing, the board design must incorporate a high-speed transmission interface and adatpable image preprocessing functionality.
In this thesis, we present a high-speed image capture board design based on IEEE 1394 interface.In addition, it uses a FPGA (Field Programmable Gate Arrays) chip for image processing.This makes the board highly reconfigurable and extensible.
There are three features in our image capture board implementation.First, we use IEEE 1394 as an I/O interface, so the input image can be directly processed without AD/DA convertion.Second, the on-board image preprocessing achieve load-sharing with CPU.And the incorporation of the FPGA chip provides high system extensibility.Third, the FPGA design reduces the complexity of hardware circuits.This also reduces the space of hardware circuits and improves the system stability.
