| Summary: | 碩士 === 國立雲林科技大學 === 電子與資訊工程研究所碩士班 === 92 === Motion Estimation techniques are extensively used in image processing and compression. Generally, the reduction of computation complex and the improvement of calculation accuracy are the main research issue. This thesis will discuss and design an optical mouse system on a chip by using a skillful full search algorithm which possesses high accurate and easy module characters. The SoC of optical mouse system includes three IP’s (Intellectual Property): Image sensor IP, ADC IP (Analog/Digital Converter) and DSP IP. Among these IP’s, Image sensor and ADC are supported by company. This thesis focuses on the VLSI design of the digital image processing and system integration. From the SoC prototyping implementation, Experimental results show that the image sensor and the ADC have rather serious noise issues. These issues will make the optical mouse operation not correct. We are proposal “The optical navigate motion direction predict algorithm”( patent number : 91104907) to overcome this problem and made the optical mouse operation optimum. Finally, The SoC system has been implemented based on TSMC 0.35um CMOS process. The chip size is about 2508 × 2900 um. In order to measure this SoC chip, we simultaneously use an optical measure machine, digital test pattern and logical analyzer to measure the image sensor IP , ADC IP and digital signal processor IP respectively. After cross measurement, we achieve the measurement range convergence to resolve some layout problems. At last, the measurement results prove the optical mouse system on a chip function design is correct and meet the low-cost requirement.
