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 do mean by mnemonics in microprocessors?
A mnemonic could be used anywhere, not just microprocessors. It's a group of letters so you could remember the parts of something.
Example: MRS. NERG
Movement, Reproduction, Sensitivity, Nutrition, Excretion, Respiration and Growth.
This is a mnemonic for the characteristics of living organisms.
It is not true.
What is duty cycle in microprocessor?
It is the ratio of the on and off time or the clock signal, which is generated by the clock generator...
What are microchips and how are they related to integrated circuits?
Basically they can be considered the same thing.
Micro chip may refer to the fact that it contains a micro processor.
A microprocessor is an integrated circuit that is designed to handle instructions from a software program and form the core of a computer system.
Integrated circuits are any type of device, that has many components etched onto a single piece of silicon and embedded in a plastic package with conducting legs. They include microprocessors, but could be amplifiers, logic gates, memory storage, complete radios, or other dedicated circuits that do one job very well.
Are trackerballs monitors and video chips all part of central processing unit of a computer?
No a trackball and a monitor would be called periferal devices. The video chips are normally on a separate 'video card' which plugs into the motherboard, though it is possible for it to be built onto the mother baord and share the main system memory, this would still not constitute it being part of the CPU.
What basic components determine the US GDP?
Components that determine the U.S. GDP are : Consumption, the amount that consumers pay for goods; Investment, the amount of money spent on new production facilities, that is, plants and facilities; Services
What is overflow bit in register?
In Computerprocessors, the overflow flag (sometimes called Vflag) is usually a single Bitin a system Status_registerused to indicate when an Arithmetic_overflowhas occurred in an operation.
What was Intel's first multicore processor?
Intel's first multicore processor was the Xeon, followed the same year (2002) by the Pentium IV. The two cores were implemented in a hyperthreading configuration, allowing two simultaneous threads when both threads were in the same process address space.
Independent cores (in different address spaces) were supported starting with the Core-2 Duo. This configuration extended the hyperthreading model to include duplicating enough of the bus interface unit to allow two unrelated threads to run simultaneously.
1 MB = 1024 x 1024 bytes = 1,048,576 bytes 1 KB = 1024 bytes So, 100 MB = 100 x 1024 x 1024 bytes = 100 x 1024 KB = 102,400 KB (104,857,600 bytes).
Different parts of the system unit or CPU?
diffent types of register, memory,ALU,timing and control unit
Microprocessor without Interlocked Pipeline Stages
Million Instructions Per Second
When Running a processor at a speed higher than its rated clock speed is?
It's called "overclocking".
Write an assembly language program to multiply an 8-bit signed number by a 8-bit signed number?
MVI A, 30h
MVI B 20h
MUL A,B
OUT port1
HLT
Level 2 cache (L2 cache).
There is no specific name for memory caches based on physical location. CPU memory caches are named for function, not location.
As such, there are Level 1, Level 2, and Level 3 caches (and, theoretically, there's nothing preventing Levels 4 and up from being created). Each can be located anywhere (on-die, in-package, off-chip, etc.) depending on the design of the CPU and motherboard.
Modern x86 chips from Intel and AMD include up to L3 cache on-die.
Does a 1.6 gz duel processor mean you have 2.2 ghz?
No, It means that you can run two different programs simultaneously that take up the 1.6ghz without hindering the other.
What is the time to execute a 3 clock cycle instruction in a 25Mhz processor?
The time to execute a 3 clock cycle instruction in a 25MHz processor is 120ns.
One clock cycle is 40ns, 1/25Mhz, so three of them are 120ns.
Ten microprocessors are the 4004, 4040, 8008, 8080, 8085, 8086, 8088, 80286, 80386, and 80486.
There are many more, and this list only included some of the Intel microprocessors, in mostly historical order.
