摘　　要：针对IEEE1394串行总线的链路层,完成了链路控制器等时传输模式的设计与实现;首先,在分析IEEE1394链路层功能的基础上,设计了等时传输模式链路控制器的总体结构以及等时传输的过程;其次,进行了模块划分,完成了先进先出存储器(FIFO)、接收器,循环计时器,循环监视器的逻辑设计方案;最后采用硬件描述语言对设计进行了可综合描述,并采用软件仿真和FPGA原形系统调试进行了功能验证,结果表明链路控制器运行稳定,可以高速地完成数据传输。In accordance with the Link Layer of IEEE1394 serials bus, this paper accomplishes the design and the implementation of the isochronous transmission mode link layer controller. The paper first designs the structure of the isoehronous transmission mode link layer controller and the isochronous transfer process. Next, the paper partitions the modules and completes the logical design of FIFO storage, receiver, cyclic timer and the cyclic monitor. Finally the paper gives a general description in hardware description language and implements the function verification with software simulation and FPGA prototype system debugging. The result shows the stable run of the link controller and the capability of high speed data transmission.
