近年來嵌入式系統蓬勃發展，嵌入式系統性能越來越強大。多媒體串流應用已經開始朝向嵌入式系統發展。然而網路快速興起，使得多媒體串流伺服器負擔越來越重，為了有效分擔伺服器的負擔，使用P2P網路架構可以降低伺服器的負擔。本論文提出一個對於P2P多媒體串流有效的排程演算法並在國內工研院晶片中心研發的PAC Duo FPGA發展平台上研究並探討。
本論文主要研究分兩部分，第一部分是以PAC Duo FPGA硬體方面為基礎，搭配具有彈性、擴充性的Linux作業系統核心，發展硬體所需的驅動程式以及DSP控制解碼播放程式，第二部分則是設計適用於PAC Duo FPGA發展平台的多媒體串流排程演算法，包括了掃描節點、節點資訊紀錄、片段排程、播放緩衝區設計。最後根據實做部份進行分析比較，並改進與修正排程系統，以達到完善系統。

In recent years, development of embedded systems is getting increasingly more and more popular. Multimedia streaming applications are developed on embedded system platforms. However, the rapid rise of the network makes multimedia streaming servers heavy. In order to share the servers’ loading effectively, P2P network architecture can be used to reduce the burden on the server. This paper presents the P2P effective scheduling algorithm for multimedia streaming developed on PAC Duo FPGA platform.
The associated research about the paper is divided into two parts. One is described the development of PAC Duo FPGA-based hardware drivers and player with DSP video decoder on Linux Operating System. The latter part is the design for the development streaming multimedia scheduling algorithms on PAC Duo FPGA platform, including the Scanning Node, Node Information Records, Segment Scheduling and Play Buffer. Finally, according to analysis results of proposed effective scheduling on P2P network, in order, we can provide suggestion and advice to improve the system.
