Muhammed Riyas A.M, resourceone.infosor,Dept. Of E.C.E,MCET Pathanamthitta. Intel contain a bit data bus.
Note — This is the only flag register in which is not accessible by user.
Parity FlagL: It occupies the second bit of the flag register. Carry Flag: It occupies the zeroth bit of the flag register.
If the arithmetic operation results in a carry if result is more than 8 bit , then Carry Flag is set; otherwise it is reset. The size of these registers is 16 bits because the memory addresses are 16 bits.
They are :- Program Counter: This register is used to sequence the execution of the instructions. The function of the program counter is to point to the memory address from which the next byte is to be fetched.
When a byte machine code is being fetched, the program counter is incremented by one to point to the next memory location.
Stack Pointer: It is used as a memory pointer. Example — Here two binary numbers are added. The result produced is stored in the accumulator.
Seeing its importance, it has been introduced in the syllabus of Engineering. The Advanced Microprocessor Model Question Paper is just a suggestion for the students which includes the most important questions of the subject.
Student have to do 5 question among all. Explain with Example.
Explain with their advantage and disadvantage? Ques 2. Attempt any two of the following. Also explain the concept of Memory segmentation in microprocessor with diagram.
How does it speed up the program execution? Explain with diagram.
Ques 3. Attempt all of the following.
An 8- or bit processor may be selected over a bit processor for system on a chip or microcontroller applications that require extremely low-power electronics , or are part of a mixed-signal integrated circuit with noise-sensitive on-chip analog electronics such as high-resolution analog to digital converters, or both.
Running bit arithmetic on an 8-bit chip could end up using more power, as the chip must execute software with multiple instructions.
Such products as cellular telephones, DVD video system and HDTV broadcast systems fundamentally require consumer devices with powerful, low-cost, microprocessors. Increasingly stringent pollution control standards effectively require automobile manufacturers to use microprocessor engine management systems to allow optimal control of emissions over the widely varying operating conditions of an automobile. Non-programmable controls would require complex, bulky, or costly implementation to achieve the results possible with a microprocessor.
A microprocessor control program embedded software can be easily tailored to different needs of a product line, allowing upgrades in performance with minimal redesign of the product. Different features can be implemented in different models of a product line at negligible production cost.
Microprocessor control of a system can provide control strategies that would be impractical to implement using electromechanical controls or purpose-built electronic controls. For example, an engine control system in an automobile can adjust ignition timing based on engine speed, load on the engine, ambient temperature, and any observed tendency for knocking—allowing an automobile to operate on a range of fuel grades.
History[ edit ] The advent of low-cost computers on integrated circuits has transformed modern society. General-purpose microprocessors in personal computers are used for computation, text editing, multimedia display , and communication over the Internet.
Many more microprocessors are part of embedded systems , providing digital control over myriad objects from appliances to automobiles to cellular phones and industrial process control.
The first use of the term "microprocessor" is attributed to Viatron Computer Systems  describing the custom integrated circuit used in their System 21 small computer system announced in By the late s, designers were striving to integrate the central processing unit CPU functions of a computer onto a handful of very-large-scale integration metal-oxide semiconductor chips, called microprocessor unit MPU chipsets.
Building on an earlier Busicom design from , Intel introduced the first commercial microprocessor, the 4-bit Intel , in , followed by its 8-bit microprocessor in AL-1, an 8-bit CPU slice that was expandable to bits.
The first microprocessors emerged in the early s and were used for electronic calculators , using binary-coded decimal BCD arithmetic on 4-bit words.
Other embedded uses of 4-bit and 8-bit microprocessors, such as terminals , printers , various kinds of automation etc. Affordable 8-bit microprocessors with bit addressing also led to the first general-purpose microcomputers from the mids on.
Since the early s, the increase in capacity of microprocessors has followed Moore's law ; this originally suggested that the number of components that can be fitted onto a chip doubles every year.
With present technology, it is actually every two years,  and as a result Moore later changed the period to two years. This section relies too much on references to primary sources. Please improve this section by adding secondary or tertiary sources. March Further information: Central Air Data Computer In , Garrett AiResearch who employed designers Ray Holt and Steve Geller was invited to produce a digital computer to compete with electromechanical systems then under development for the main flight control computer in the US Navy 's new F Tomcat fighter.
The design was significantly approximately 20 times smaller and much more reliable than the mechanical systems it competed against, and was used in all of the early Tomcat models.The was not, however, an extension of the design, but instead the culmination of a separate design project at Intel, arising from a contract with Computer Terminals Corporation , of San Antonio TX, for a chip for a terminal they were designing,  the Datapoint —fundamental aspects of the design came not from Intel but from CTC.
Addressing modes in 8085 microprocessor
The chip was packaged in a large ceramic pin DIP package , while most 8-bit microprocessors such as the Intel used the more common, smaller, and less expensive plastic pin DIP. AL-1, an 8-bit CPU slice that was expandable to bits.
From to , the bit x86 architectures became increasingly dominant in desktop , laptop , and server markets, and these microprocessors became faster and more capable. If memory addressing is simplified so that memory is only accessed in bit units, memory will be used less efficiently.
