What is the difference between machine instruction format and micro instruction format?
Micro instrution
A single instruction in microcode. It is the most elementary instruction in the computer, such as moving the contents of a register to the arithmetic logic unit (ALU). It takes several microinstructions to carry out one complex machine instruction (CISC). Also called a "micro-op" or "µop," microinstructions differ within the same computer family and even the same vendor. For example, although all are x86 chips, the microcode for Intel's Pentium 4, Pentium M and AMD's Athlon are not the same. The software programmer never sees microinstructions, and they are not documented for the public.
Machine code - simple instructions that are executed directly by the CPU.
In other words, it takes many micro instructions to make a machine code. Micro Instructions work with the ALU wheras Machine Code works directly with the CPU
What are the instructions a CPU uses?
CPU is main part of computer,It processes the data using the registers inside the CPU. These are of different types and have different purpose of use. Due to these registers the CPU done processing.
What is the difference between a microprocessor and human brain?
Both a human brain and a CPU perform computations.
A CPU is basically a serial device (a Von Neumann machine). Its computation steps are discrete. Its operations are chosen from a small set. It does some things, like arithmetic, extremely well. It never gets tired. It uses lots of energy. It interfaces with external devices (memory, ALU, Input and Output).
A human brain is a parallel interconnected device. Its computation steps are continuous. It has a large set of operations. It does some things, like face recognition, extremely well. It often gets tired. It is much more efficient energetically than a CPU. It interfaces with external devices (eyes, ears, nose, mouth, skin).
This is not even scratching the surface - Go read, say, "Goedel, Escher, Bach" in order to get a feel for how large this question is.
What are advantages of the Spiral Model?
Advantages
1. Estimates (i.e. budget, schedule, etc.) become more realistic as work progresses, because important issues are discovered earlier.
2. It is more able to cope with the (nearly inevitable) changes that software development generally entails.
3. Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.
What are some examples of microcomputers?
Desktop computers,video game consoles, laptop, etc. are the examples of micro computer. Just about any computer that you can sit on your desk as a self-contained unit is in the class "microcomputer". This includes PCs, Macs and even laptops.
Moving back in the early days:
Apple II family
Commodore 64/ 128 Listed on Guiness as the best selling Micro computer of the 80's.
Amiga
I still think the C=64/C=128 is the best micro around :-)
( If you are looking at this question right now you probably are using a microcomputer.)
What does the CPU consist of and what do the letters CPU stand for?
The letters CPU stand for Central Processing Unit. A CPU is made up of the control unit, instruction decoding unit and an arithmeticlogic unit.
What must be true before MMX SSE SSE2 and 3D Now technology can improve multimedia performance?
1. The processor must support those instructions.
2. The software must be (re)written to take advantage of them.
What is the difference bitween Pentium D Pentium R processors?
The Pentium D is basically a dual-cored version of the Pentium 4. It is nowhere near as efficient or powerful as a Core 2 Duo, and it actually generates slightly more heat than a Pentium 4.
What does a microprocessor in a TV do?
Bottemline it processes information like any other pocessor its just smaller in size. usually a micro processor in a tv is what allows settings to be changed digital channels and codes translated into a picture pr to be more exact pixil position.
A CPU typically looks like a small square with a very high number of tiny golden pins on one side, a band of green silicon around the edges, and a thick metal covering plate on top. It will usually have some kind of emblem or writing on the top.
What factors determine the power and speed of microprocessor chips?
There are several aspects which touch completely different aspects of processor design. For instance:
- Manufacturing process (e.g. "32 nm" process)
- Voltage, currents and resistance (depend on process)
- Clock speed (depends on all above, e.g. "1200 MHz")
- Available cooling (limits clock speed)
- Instruction set design (some instruction sets are faster than others)
- Number of processor cores (more cores means that individual cores work slower than a single core would)
There are even more factors, but most of them are design-specific (like slow bus clock or memory clock).
What is the function of CLKOUT pin in microprocessor 8085?
The CLK signal in the 8085 is the system clock, which is the External Input Frequency or Crystal divided by two. It can be used to develop bus control logic, because it is essentially the inverse of ALE for one half clock cycle.
What is the Advantages and Disadvantages of von neumann computer architecture?
Disadvantages
-Executes instruction serially.
-Limited by the times it takes to process each instruction.
-some registers are idle(not being used)during the fetch-decode-execute-reset-cycle.
Advantages
-Is that seperate data bus are not required.
-program locality
What are the operations of a microprocessor?
A microprocessor manipulates data in a computer system. The central processing unit acts as the brain of a computer and consists of one or more microprocessors made up of several thousand transistors on a single integrated circuit. The microprocessor works in conjunction with other parts of the computer to compute arithmetic and logic functions to handle tasks using an instruction set to perform all tasks within a computer.
Microprocessor initiated operations are operations that the microprocessor itselp start.
These are usually one of four operations.
- Memory Read
- I/O operation
- Memory write
- I/O read
How do you figure out the clock speed of a computer?
Simply click on the start button go to control panel and find the system icon and click on it the processor speed and memory should be listed or download a detailed descriptions of your computer components. Or you can download a program called Sandra.
What is the latest ICT hardware?
ICT Printing Press is product for offset Printing Press. It simply takes few related parameters of customer's order as input and present total estimation of project, most economical job size, machine, paper stock cutting plan for sheet or reel. It is newest ICT HARDWARE.
What is another name of central processing unit?
The CPU, or central processing unit, is the "brain" of the computer, which enables it to perform all of its necessary functions. The CPU is also called the microprocessor.
What is faster CPU or system bus?
I suppose you mean "CPU"
The system bus is typically set at a vastly lower frequency than the CPU. They handle different things, so comparing them to each other for "speed" isn't really possible.
This is similar to asking if the speed of a plane is higher than the hardness of a rock.
Where can I compare different processors?
The best comparison site for computer processor units (CPU) is CPU Benchmark. That site enables direct comparisons, but other sites like Consumer Reports also have less detailed comparisons as well.
What contain in microprocessor?
Well microprocessors are the most important thing in a computer which contains the following components:
1)ALU-arithmetic logic and control unit which is used for the arithmetic operations such as add,suband logical operations include logic AND,logic OR etc
2)Control unit-an important aspect of the microprocessors which generates signals for any operation to be performed by the microprocessor
3)Registers-used for the storage puposes including accumulator

What is the relationship between a processor and a motherboard?
The central processing unit (CPU) is plugged into the motherboard. Everything else in the computer is directly or indirectly plugged into the motherboard. There are expansion boards, for instance, which have all kinds of processors on them, but they are plugged into the motherboard meaning it is the base board that everything ultimately connects to, like the foundation of a house.
This creates a connection from everything to the CPU. This is necessary because the CPU, like the motherboard, is central to the control of the computer as a whole. It ultimately controls the lowest level functions of the operating system and actually controls most things that happen in a computer. Actually, more than saying control, it is most of the work of the computer. It does the numeric operations that are what a computer, for the most part, does.
CPU = brains, motherboard = connections to the periphery
Core is the centre part of any celestial body.
<<>>
In electrical terms a core is an iron frame that wire coils are wrapped around to concentrate the magnetic flux that surrounds a wire when current flows through it. A good example of a core is in a transformer where both the primary and secondary windings are wound on to the same core. The magnetic flux that surrounds the primary coil when it draws a current will cut the secondary coil and induce a voltage into it. The core concentrates and directs the lines of magnetic force for maximum use by the secondary coil.
