MICRO PROCESSOR AND ITS APPLICATIONS
[attachment=20591]
Define Microprocessor?
Microprocessor is a multipurpose, programmable, clock-driven, register based
electronic device that reads binary instructions from a storage device called
memory, accepts binary data as input and processes data according to those
instructions, and provides as output.
What is Hardware and Software?
The physical components of the system i.e. computer are called Hardware.
Group of programs is called software.
Why the microprocessor is viewed as a programmable Device?
Microprocessor is programmable because it can be instructed to perform given
tasks within its capability. Microprocessor is designed to understand and execute
many binary instructions.
What is Central processing Unit ( CPU ) ? And Write the use of it.
CPU is a heart of the computer. Central processing Unit controls the operation
of the computer. In a microcomputer the CPU is a microprocessor. The CPU
fetches binary coded instructions from memory, decodes the instructions into a
series of simple actions and carries out these actions in a sequence of steps.
What is a chip?
A chip is also called an integrated circuit. Generally it is a small, thin piece
of silicon onto which the transistors making up the microprocessor have been
etched. A chip might be as large as an inch on a side and can contain tens of
millions of transistors. Simpler processors might consist of a few thousand
transistors etched onto a chip just a few millimeters square.
What is System Bus?
The System bus is a communication path between the microprocessor and
peripherals. It is nothing but a group of wires to carry bits.
What is Address Bus?
The address bus consists of 16, 20, 24 or 32 parallel signal lines. On these
lines the CPU sends out the address of the memory location that is to be written to
or read from. The number of address lines determines the number of memory
locations that the CPU can address. If the CPU has N address lines, then it can
directly address 2N memory locations. Simply, we can say that Address Bus is
used to carry the address.
What is Data Bus?
The data bus consists of 8, 16, or 32 parallel signal lines. The data bus lines
are bidirectional. This means that the CPU can read data in from memory or from
a port on these lines, or it can send data out to memory or to a port on these lines.
Simply we can say that data bus is used to carry the data.
What is Assembly Language?
A medium of communication with a computer in which programs are
written in mnemonics. Binary instructions are given abbreviated names called
mnemonics, which form the assembly language for a given processor.
What is Machine Language?
The binary medium of communication with a computer through a designed
set of instructions specific to each computer.
What is Bit-Slice processor?
For some Applications , general purpose CPUs such as the 8080 and 6800
are not fast enough or do not have suitable instruction sets. For these
applications ,several manufacturers produce devices which can be used to build
the custom CPU. This family includes 4 bit ALUs, multiplexers, sequencers and
other parts needed for custom building a CPU. The term slice comes from the
fact that these parts can be connected in parallel to work with 8 bit words, 16-
bit words, or 32 bit words.
