8085MICROPROCESSOR ARCHITECTURE
In the commons language the architecture means structural design of a building. Similarly by microprocessor architecture in a broad sense we mean the structural design of the digital circuit responsible for computing. The digital circuit of the microprocessor is designed in such a way that if a proper binary input called instruction) is given to this circuit we get the desired output. To understand this we can see the behaviour of a two input AND gate in which we get 1 as an output if and only if both the input are 1 similarly an adder circuit gives the output which is the addition of two input bits. Hence we can imagine that how complicated is the design of the digital circuit of an microprocessor which can give the output according to various instruction given to it like add subtract move and or exclusive or etc. This can be achieved in different manner. That means there may be many possible digital circuits to achieve in different manner. That means there may be many possible digital circuits to achieve the same output. Therefore the architecture of two different microprocessors might be different. The way they ad two numbers may be quit similar but a complicated task like finding out the tangent of an angle will be performed in a different way in two different microprocessors. One microprocessor may perform it very easily while the other may with difficulty.
Various features which affects the architecture of a microprocessor are:
a.Length of data word which is decided by the size of the data bus.
b.The size of memory accessed by the microprocessor which is decided by the size of the address bus.
c.The speed of execution of instruction which id seceded by the clock frequency at which microprocessor can operate.
d.The type of registers.
e.The types of instructions.
f.The types of addressing modes.
g.Various supporting hardware which are compatible with that microprocessor.
These are various features which make are microprocessor different from other microprocessor. We will discuss these features in detail in different parts of this book especially for 8085 microprocessor. Various advanced processors are discussed in chapter 11.
Q. What is the Voltage controlled resistance region? In this region the JFET can actually be employed as a variable resistor whose resistance is controlled by the applied gate
RST Restart Instructions Restart instructions are one byte call instructions. Called location for each restart instruction is predefined on page 0 ( read only memory). They
Q. Illustrate Inductance with example? An ideal inductor is also an energy-storage circuit element (with no loss associated with it) like a capacitor, but representing the magn
Explain the term half duplex transmission. A half duplex channel can receive and send, but not at similar time. It's as a one-lane bridge where two-way traffic should give way
Q. Consider an amplifier as a voltage source with an internal resistance of 72 . Find the turns ratio of the ideal transformer such that maximum power is delivered when the amplif
Magnetic permeability and the B/H curve To measure the relationship between field strength H and flux density B for a material, a sample is made into a closed ring and a magne
Turn-on, turn-off, and storage delay: The Bipolar transistor shows a few delay characteristics while turning on and off. Most of the transistors, and particularly power transi
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
Earth Leakage : Earth leakage takes place when, through some fault in an appliance or its connections. Electric current escapes to earth i.e. the body of the appliance become 'liv
Input Characteristics Transistors can be operated in the switching mode. If base current IB is zero transistor is in an ON state behaves as a switch. If the base cur
