1、外文资料Outline,Application and Development of the singlechipThe singlechip is one kind of integrated circuit chip,which uses the ultra large-scale technology and has the data-handling capacity(for example arithmetic operation,logic operation,data transfer,interrupt processing)the microprocessor(CPU),ra

2、ndom access data-carrier storage(RAM),read-only program memory(ROM),input output circuit(I/O),possibly also includes fixed time the counter,serial passes unguardedly(SCI),demonstration actuation electric circuit(LCD or LED actuation electric circuit),pulse-duration modulation electric circuit(PWM),s

3、imulation multichannel switch and A/Electric circuit and so on D switch integrates to together the monolith chip on,constitutes to be smallest the computer system which however consummates.These electric circuits can under the software control accurate,be rapid,highly effective complete the procedur

4、e designer preset the duty.From this looked that,singlechip has the function which the microprocessor does not have,it may alone complete the intellectualization control function which the modern industry control requests,this is singlechip biggest characteristic.However singlechip also is different

5、 with the single trigger,the chip before the development,it only has the function greatly strengthened ultra large scale integrated circuit,if entrusts with it the specific procedure,it then is youngest,the integrity microcomputer control system,it(PC machine)has the essential difference with the si

6、ngle trigger or the personal computing,singlechip application belongs to the chip level application,needs the user to understand singlechip chip the structure and the command system as well as other integrated circuit application technologies and the system design need theory and technology,with suc

7、h specific chip design application procedure,thus causes this chip to have the specific function.The different singlechip has the different hardware characteristic and the software characteristic,namely their technical characteristic is different,the hardware characteristic is decided by singlechip

8、chip internal structure,the user must use some kind of singlechip,must understand whether this product does satisfy the characteristic target which the need the function and the application system requests.Here technical characteristic including function characteristic,control characteristic and ele

9、ctrical specification and so on,these information needs to obtain from in the production merchant technical manual.The software characteristic is refers to the command system characteristic and the development support environment,the instruction characteristic is singlechip addressing way which we i

10、s familiar with,the data processing and the logical processing way,input-output characteristic and to power source request and so on.The development support environment is compatible and the probability including the instruction,supports the software(to contain may support development application pr

11、ocedure software resources)and the hardware resources.Must use some model singlechip to develop own application system,master its structure characteristic and the technical characteristic is that we need.Singlechip control system could substitute for before uses control system which the complex elec

12、tronic circuit or the digital circuit constituted,might the software control realizes,and could realize the intellectualization,now singlechip control category omnipresent,for example correspondence product,domestic electric appliances,intelligent instrument measuring appliance,process control and s

13、pecial-purpose control device and so on,singlechip application domain was more and more widespread.Indeed,singlechip application significance is far is not restricted in its application category or from this the economic efficiency which brings,it fundamentally changed the traditional control method

14、 and the design thought more importantly.Is controls technical a revolution,is an important milestone.2.The MCU s development outlineIn 1946 first electronic accounting machine birth until now,only then 50 years,depends upon microelectronic technology and the semiconductor technology progress,from t

15、he electron tube-transistor-integrated circuit-large scale integrated circuit,now together on the chip definitely may integrate several million even more than ten million transistor,causes the computer volume slightly,the function is stronger.Specially in the nearly 20 years time,computer technology

16、 obtained the rapid development,the computer in the industry and agriculture,the scientific research,the education,the national defense and the aerospace domain has obtained the widespread application,computer technology already was a national modern science and technology level important symbol.Sin

17、glechip is born in the 20th century 70s,looks like F8 monolithic microcomputer which Fairchid Corporation develops.The so-called singlechip is uses the large scale integrated circuit technology the central processing element(Center Processing Unit,Also is Chang Cheng CPU)and the data-carrier storage

18、(RAM),the program memory(ROM)and other I/O passes integrates unguardedly on together the chip,constitutes a smallest computer system,but modern singlechip then has added on the severance unit,fixed time unit and A/D transformation and so on more complex,more perfect electric circuit,causes singlechi

19、p the function more and more formidable,the application is more widespread.The 20th century 70s,microelectronic technology is being at the development phase,the integrated circuit belongs to the scale development time,each kind of new material new craft not yet mature,singlechip still occupied the p

20、rimary development phase,the part integration scale also quite small,the function quite was simple,CPU,RAM had generally has also included some simple I/O integrates to the chip on,looks like Farichild Corporation to belong to this type,it also must be joined to the periphery other processing electr

21、ic circuits just now to constitute the integrity the computing system.The similar singlechip also has Zilog Corporation the Z80 microprocessor.In 1976 INTEL Corporation has promoted the MCS-48 singlechip,this time singlechip is the genuine 8 monolithic microcomputers,and pushes to the market.It is y

22、oung by the volume,function entire,the price has lowly won the widespread application,has laid the foundation for singlechip development,becomes in singlechip history the important milestone.Under the MCS-48 leadership,after that,each big semiconductor company developed and has developed own singlec

23、hip one after another,looked like Zilog Corporation the Z8 series.To the beginning of the 80s,singlechip has developed to the high performance stage,looks like INTEL Corporation the MCS-51 series,Motorola Corporation 6,801 and 6,802 series,Rokwell Corporation 6,501 and 6,502 series and so on,In addi

24、tion,Japans famous electrical company NEC and HITACHI all one after another developed had oneself characteristic the special-purpose singlechip.The 80s,world each big company competes to develop the variety multi-purpose strong singlechip,some severaldozens series,more than 300 varieties,this time s

25、inglechip belongs approximately truely monolithic,mostly integrated CPU,RAM,ROM,number many I/O connection,many kinds of interruption system,even also has some to bring A/D switch singlechip,function more and more formidable,RAM and ROM capacity also more and more big,the addressing space even may r

26、each 64kB,may say,singlechip developed to a brand-new stage,the application domain has been more widespread,many domestic electric appliances moved towards the intellectualized development path which controlled using singlechip.After 1982,16 singlechips are published,represent the product are INTEL

27、Corporations MCS-96 series,16 singlechips compare 8 machine,the data width increased a time,real-time processing ability stronger,the basic frequency is higher,the integration rate had achieved 120,000 transistors,RAM increased to 232 bytes,ROM then has achieved 8kB,and had 8 interrupt sources,at th

28、e same time has disposed multichannel A/D transformation channel,high speed I/The O processing unit,is suitable for the more complex control system.After 90s,singlechip obtained the rapid development,the world each big semiconductor company has developed a function more formidable singlechip one aft

29、er another.American Microchip Corporation had issued one kind of incompatible MCS-51 new generation of PIC series singlechip,has aroused the field widespread interest completely,its product only then 33 simplified the set of instructions to attract many users specially,caused the people to concentra

30、te from the INTEL 111 complex instructions.The PIC singlechip has obtained the fast development,holds the small space in the field.The afterwards matter,the familiar singlechip public figures quite have been all clear,more monolithic aircraft types pour out,MOTOROLA Corporation had issued one after

31、another the MC68HC series singlechip,Japans several famous companies all developed a performance stronger product,but Japans singlechip used in generally the special-purpose systems control,but did not look like company and so on INTEL puts in to the market forms the general singlechip.For example N

32、EC Corporation produces the uCOM87 series singlechip,its representative works uPC7811 is one kind of performance quite outstanding singlechip.MOTOROLA Corporations characteristic and so on MC68HC05 series its high speed low price has won many users.Zilog Corporations Z8 series product representative

33、 works are Z8671,contains BASIC the Debug interpreter,enormous place then user.But American country half COP800 series singlechip then uses the advanced Harvard structure.ATMEL Corporation then perfectly unifies singlechip technology and the advanced Flash memory technology,has issued the performanc

34、e quite outstanding AT89 series singlechip.Including company and so on Chinas Taiwan HOLTEK and WINBOND in abundance has also joined singlechip development ranks,by reason of their inexpensive superiority,shares cup of beautiful thick soup.In 1990 American INTEL Corporation promoted 80,960 super 32

35、singlechips to cause the computer stir,the product has put in the market one after another,became in singlechip history an important milestone.This period,in singlechip field,singlechip variety extraordinary splendour,competes to be the most unusual.Some 8,16 even 32 machine,but 8 singlechips by its

36、 price inexpensive,the variety complete,the application software rich,the support environment were still full,characteristic and so on development convenience but are occupying the dominant position.But INTEL Corporation by reason of their abundant technology,the performance outstanding type and the

37、 good foundation,at present was still singlechip mainstream product.Only is the 90s intermediate stages,INTEL Corporation is busy is developing their personal computing microprocessor,not the enough energy continued singlechip technology which develops oneself creates leads,but by company and so on

38、PHILIPS continues to develop the C51 series singlechip.3.Singlechip application domainMCU applications SCM now permeate all areas of our lives,which is almost difficult to find traces of the field without SCM.Missile navigation equipment,aircraft,all types of instrument control,computer network comm

39、unications and data transmission,industrial automation,real-time process control and data processing,extensive use of various smart IC card,civilian luxury car security system,video recorder,camera,fully automatic washing machine control,and program-controlled toys,electronic pet,etc.,which are inse

40、parable from the microcontroller.Not to mention the area of robot control,intelligent instruments,medical equipment was.Therefore,the MCU learning,development and application of the large number of computer applications and intelligent control of the scientists,engineers.Singlechip widely applies in

41、 the instrument measuring appliance,the domestic electric appliances,the medical equipment,domain and so on aerospace,special purpose equipment intellectualized management and process control,may divide the following several categories approximately:1.On intelligent instrument measuring appliance ap

42、plicationSinglechip has the volume small,the power loss low,the control function strong,the expansion is nimble,merit and so on microminiaturization and easy to operate,widely applies in the instrument measuring appliance,the union different type sensor,may realize such as physical quantity the and

43、so on voltage,power,frequency,humidity,temperature,current capacity,speed,thickness,angle,length,degree of hardness,element,pressure survey.Uses singlechip control to cause the instrument measuring appliance digitization,the intellectualization,the microminiaturization,also the function compares use

44、s the electron or the digital circuit is more formidable.For example precise measurement equipment(dynamometer,oscilloscope,each kind of analyzer).2.In industry control applicationMay constitute the various formats control system,the data acquisition system with singlechip.For example the factory as

45、sembly line intellectualized management,the elevator intellectualization control,each kind of alarm system,constitutes two cascade control systems with the computer networking and so on.3.In domestic electric appliances applicationMay say like this that,the present domestic electric appliances basic

46、ally have all used singlechip control,praised,the washer,the electric refrigerator,the air conditioner,the color television,other acoustic video frequency equipments from the electricity food,again to the electronic weighting equipment,all kinds of,omnipresent.4.In computer network and correspondenc

47、e domain application Of the modern singlechip has the correspondence connection generally,may very conveniently and the computer carries on the data communication,for provided the extremely good physical conditions application in between the computer network and the communication facility,the presen

48、t communication facility basically has all realized singlechip intelligence control,from the handset,the telephone,the small program controlled switch,the building automatic correspondence ringing system,the train wireless correspondence,again the mobile phone which everywhere to the routine work in
