Microprocessors
A microprocessor is the heart of any computer, whether it is a server, a desktop machine, or a laptop. This single chip contains the arithmetic, control, and logic circuitry necessary to interpret and execute computer programs.

What are the applications of microprocessors?
The applications of microprocessors are identical to those of any other programmable electronic digital computers, except due to its significantly smaller size and reduced cost compared to the other programmable electronic digital computers that preceded it these applications can now be computerized too in many places and systems where it was not practical to computerize them before the development of microprocessors.
Can you use a printed circuit board on an embedded system?
I cannot imagine a modern embedded system that is not built on a printed circuit board.
it referred to the clock speed ,commercially this is widely used in defining clock speed of oscillators connected with processors for generating timing signals..
2.10ghz means 2.10*10^9 Hertz or this much signals per second
Varies from machine to machine:
- many early machines had address busses only 12 to 18 bits wide
- early microprocessors has address busses 10 to 14 bits wide
- 16 bit address busses were common on microprocessors in the early 1980s
- the 8086 had a 20 bit address bus and the 68000 a 24 bit address bus
- most modern computers have 32 bit address busses with high-end ones having as many as 64 bit address busses
Describe the function of the instruction set of a CPU?
They tell the CPU where to find the data, when to read it, and what to do with it.
several companies but the biggest ones: INTEL and AMD.
How do you write a program on bcd addtion?
The first thing to remember is that a BCD digit is only 4 bits (a nibble).
Secondly BCD is a base 10 system so the largest number for each digit is 9 but a nibble can have a value of up to 15.
Thirdly, after each addition the resulting value has to be normalized. Here is the rule. If the resulting value is grater than 9, subtract 10 and also carry 1.
Programming this is your job.
Sinking and sourcing capability of microcontroller?
Sinking and sourcing current refers to current going into and out of the MCU (respectively)
How do you burn atmega32 avr program?
avr microcontroller can be burnt by using a burner with variety of softwares like AVR BURN O MAT....
The instruction represented by this code depends entirely on the architecture that you are trying to translate it for.
The AVR is an AV receiver. It was first introduced as a common soundtrack format by the Dolby Pro Logic company.
Why does the system idle process use a lot of CPU time?
The system idle process does not actually use any CPU time. It just merely calculates what percentage of the CPU is being used by your processes at any given time.
How can you explain process hierarchy in connection with operating systems?
what are hierachies are used for process in operating systems
Can you use a GPU and CPU in the same computer system?
Yes, in fact you should. The Central Processing Unit (CPU) is the element in your computer that does the actual computing. The Graphical Processing Unit (GPU) is part of the Video card which renders the graphics you see on screen.
Where is microprocessor placed in computer?
The central processor unit (microprocessor) is placed on the motherboard. The cooler, necessary to refrigerate the microprocessor is placed behind it.
What is the role of clock generator in microprocessor?
The clock signal in a microprocessor allows synchronization of several components of the microprocessor. The correctness of the computation of the microprocessor depends upon efficient and balanced distribution of the clock signal. The clock generator generates the clock signal.
