摘要: 近幾年關於多媒體的應用已經廣泛的出現在日常生活中,例如衛星導航、行動電話或電子書等,都能夠看到多媒體應用的蹤跡。 本論文主要目的是透過多媒體的應用,並使用市面上主流的ARM微控器,來熟悉嵌入式系統的軟硬體設計。在硬體方面以脈衝波寬調變(PWM)模式來取代DAC功能輸出;軟體部分則建立SD記憶卡的底層程序並整合FAT檔案儲存系統,使得在開發嵌入式系統時可以快速的解決檔案儲存的應用。並透過播放WAVE音樂來熟悉脈衝編碼調變(PCM)的編解碼流程,與播放MP3音樂來了解音樂壓縮編碼與解碼處理的程序。
In recent years, the applications of multimedia have widely appeared in ourdaily lives, for instance, GPS navigation systems, cellar phones and electronicbooks. You can easily spot multimedia applications everywhere. The purpose of this study was to gain an understanding of the design of embedded hardware-software systems based on commonly-used ARM microcontrollers and through the application of multimedia. In terms of hardware, pulse-width modulation (PWM) was employed to replace digital-to-analog converter (DAC) output. For software, an underlying SD card process was developed and integrated with the FAT file system, which enables rapid file storage when developing an embedded system. The encoding and decoding process of pulse-code modulation (PCM) is used in playing WAVE music files. In addition, by playing MP3 music files we can understand the encoding and decoding process of music compression.
