Design Of 1553B Bus Monitor Based On SystemC

1553B bus is internationally recognized as the standard bus,it has the advantages of high flexibility,strong anti-interference,now 1553 B bus has been gradually used in many fields of ships,tanks,subway and so on,so the research has important significance for 1553 B bus.As now,the scale of integrated circuits is becoming more and more large,on the one hand,this will improve circuit performance.Now the number of transistors that integrated one chip has been close to one billion,which makes more and more systems are achieved on a chip,but on the other hand,the integrated circuit with larger size make the design and validation more and more heavy.In order to improve the speed of verification,we can use SystemC language to finish the,design with TLM,so we can solve such problems.This paper first introduces the application and advantages of 1553 B bus,then analyze the 1553 B protocol.By these jobs,the paper analysis the bus monitor and konw the the function we should realize and the significance,The role of the bus monitor is to record and analyze the message and device status on the bus.Finally,the paper performs an overall transaction-level modeling,and describes each of the small modules.The bus monitor designed in this paper includes four units: data receiving unit,data decoding unit,data analysis unit,data error reporting unit,The data receiving unit is mainly responsible for receiving the data,and the data decoding unit decodes the incoming data on the bus And the data analysis unit is on the incoming data protocol analysis,then generate relevant information,the last data error unit generates the corresponding error interrupt,At the same time the outside world can read the bus monitor monitoring information At the end of the paper,the design is simulated to verify the correctness of the design.Finally,this paper draws this conclusionthe that the bus monitor is able to identify data errors on the bus and generate related error descriptions.
