摘　　要：本文设计的IEEE 1394事物层接口连接了PLB(Processor Local Bus)总线和1394链路层模块,主要实现1394事物层模块数据的发送和接收.首先对事物层接口进行系统结构设计,然后对PLB从接口、FIFO接口和主机访问寄存器接口这3个子模块分别进行逻辑设计,最后采用硬件描述语言对设计进行可综合描述,并使用软件QuestaSim进行仿真验证.该设计使事务层能够跨时钟域同链路层进行数据包的传输,并进行有效的数据位宽转换,提高传输效率.经过仿真验证,结果满足设计要求,表明IEEE 1394事物层接口能够正常发送和接收等时及异步数据包.The design of the IEEE 1394 transaction layer interface connecting the PLB（Processor Local Bus）with the 1394 link layer module,mainly aims to send and receive 1394 transaction layer module′s data.Firstly,the system structure of transaction layer interface is designed,and then the three submodules,including PLB slave interface,FIFO interface and host interface to access the registers are designed.Finally the hardware description language is used to describe this design,and the software QuestaSim is used to simulate and verify the result.This design of the transaction layer can transmit data packet with the link layer across the clock domain,switch data width effectively and improve the transmission efficiency.The simulation results meet the design requirements and show that the transaction layer can be capable of sending and receiving isochronous and asynchronous data correctly.
