中文摘要
FlexRay控制網路通訊協定,是未來數位化汽車的必備規格。雖然規格中主要的標準都已在2005年制定完成,但現今鮮少有相關性商品搭載在汽車之中使用。本研究論文,是實現Flexray系統中媒介存取控制層(MAC Layer)的硬體電路。其中主要的子模組分別為:連結主控端操作介面的主機控制器協定介面(Controller Host Interface, CHI)、接收CHI指令來控制所有子模組的協定操作控制器(Protocol Operation Controller, POC)、負責節點間同步的同步電路(Clock Synchronization, CS)、負責切割時槽與編排傳送資料格式的媒體存取控制器(Media Access Control, MAC)、連接實體層(Physical Layer)的編解碼器(Coding and Decoding, CODEC)及偵測接收訊號錯誤的訊框與符號處理器(Frame and Symbol Processing, FSP)。FlexRay系統中由於加入節點同步的功能,所以能夠在分時多工存取(Time Division Multiple Access, TDMA)系統中高速傳送資料;也因為傳送端具有雙通道的特性,所以具有較高的容錯性,以達到車用網路高速且穩定的資料傳輸要求。
Abstract
FlexRay communications system protocol is necessary specification of the future digitizing motor vehicle. Though the principal standard of specifications had established in 2005, little correlative commodities have used in the motor vehicle now. In this paper, I implement the hardware circuit of MAC Layer in the Flexray system. In the system, six major sub-modules: Controller Host Interface (CHI) is connecting with the Host processor interface, Protocol Operation Controller (POC) is controlling all sub-modules after receiving the orders from CHI, Clock Synchronization (CS) is synchronizing between all nodes, Media Access Control (MAC) is dividing slot and arranging the style of transmission data, Coding and Decoding (CODEC) is connecting the Physical Layer, and Frame and Symbol Processing (FSP) is detecting the error of receiving data. Because the system increases the function of synchronization between Nodes in the FlexRay system, it can transmit high data rate in the Time Division Multiple Access system (TDMA). Because the transmitter is two channels, it has the characteristic of high fault tolerance. The two characteristics meet the requirements that transmitting data is high data rate and stabilize.
