Abstract:	隨著物聯網裝置的進步與普及，資料生產的速度越來越快，對於網路及雲端伺服器的負擔越大。為了解決此問題，有了終端感測器收集的資料，在傳送前先於終端過濾或是壓縮資料的概念出現，也就是邊緣運算。本論文目的為開發出一個具有邊緣運算潛力的單板電腦，可做為物聯網機器人的控制核心，也能為相機模組提供主要運算核心，將原始相片轉換壓縮為通用影像格式等。此硬體平台運作以C4MLIB為核心，提供並協助使用者開發物聯網裝置，其設計目的在於降低使用者對硬體方面的學習成本以加速開發時間。硬體平台配有ASABUS，作為與周邊感測器資料交換的工具、乙太網路擴充介面，支援市售乙太網路物理層模組以及16MB的flash記憶體，作為紀錄資料以及定期更新韌體的程式儲存空間。 C4MLIB包含管理flash的檔案管理系統模組，本論文在移植模組至此硬體平台之餘，還針對了穩定性、壽命平衡以及檔案吞吐量等議題提出了解決方法及改善，最後以此檔案管理系統實作出In-Application Programming於本硬體平台中。 ;With the growth of IoT device, the data generated by these devices has grown rapidly, and it’s a burden for either the Internet or the cloud server. In order to solve these issue, there’s a concept that sensors must filter or compress the data they produced before sending them to the cloud server, and this concept is known as edge computing. The purpose of this research is to develop a device which has potential to become an edge computing device, IoT robot control board, or computing cortex in an camera that responsible for raw picture compressing to image format. This device is powered by C4MLIB which supports users developing an IoT devices, aims to reduce user learning time and make development more efficient. For the hardware of this device, there are ASABUS which provides a tool to users for communicating with sensors; Ethernet bus, which supports most Ethernet module in the market; Flash memory, which has 16MB memory size, it provides storage for record data and firmware. There’s file system in C4MLIB, besides porting the file system, this research also improves the performance of file system, such as stability, wear leveling, and file write throughput. At last, this research implements In-Application programming based on the file system.
