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 role does the CPU Instruction Register IR play in the decoding of machine instructions?

The IR is a register constisting of two parts, opcode and address. The opcode is decoded and gives instructions to the control unit whilst the address part is used to give the location in the memory of for example data required for a certain process

What is RAM and CPU?

RAM = Random Access Memory. That's the volatile high speed memory that is used inside a computer that lets you store internal applications and data. Everything written to RAM is lost when you turn off the computer, so usually, important data is written to a long-term storage device, such as a disk or "Flash Memory". CPU = Central Processing Unit. It is also sometimes called the ALU or Arithmetic Logic Unit. It's the part of the computer that makes decisions and causes things to happen. The CPU has built in instructions that allow it to perform some very basic tasks, such as: Add the contents of register 1 to the contents of register 2 and store the results in register 2. If the contents of register 1 are greater than the contents of register 2, continue execution of this program at line 101, otherwise continue execution at the next line. There are many such "low level" commands that are executed by the CPU, and when these simple commands are being executed at a rate of over 1 million instructions per second, you get some pretty amazing results.

Does the CPU supply provide power to a CPU fan or a case fan?

Neither, The CPU is the Central Processing Unit, it only processes information and bits of data the computer sends thru it. The motherboard supplies power to the case fan AND the CPU fan, which is supplied power from the PSU (power supply unit)

Can an Intel Core i7-3770k processor be used in a H-CUPERTINO2-H61-uA TX motherboard?

Yes! The intel Core i7-3770k is a Socket 1155 processor and the Cupertino2-H61-uA TX supports the 1155 socket.

What is the fastest computer chip?

Most people will tell you that it is impossible to answer this. First of all, there is no notion of "fastness" in computer chips. You may be asking about the highest clock speed on a processor, but that number means little by itself when it comes to performance (which is the important factor). Second, if you were to ask about the best performing processor, then you need to devise some fair way of measuring the performance of each. And finally, even if you could definitely say which chip is faster or better between a pair of chips, the "fastest" or "best" would change constantly, and so asking something like this has little meaning.

How does an Intel Pentium D CPU 3.20ghz compare to an Intel Pentium III?

It's often difficult to compare the performance of two processors, especially when one is much older. Depending on the type of computations you are doing, you may see anything from no change to a 1700% increase in the Pentium D over the Pentium III.

How can you check the CPU usage on a Windows 98 machine?

go to start>programs>acc.>system tools>system monitor.

There is also a free tool available at www.analogx.com, called netstat I think, that will give you your CPU usage and monitor the traffic in or out of your machine. They also have a great memory manager that keeps your ram from being locked up by Windows, and a bunch of other neat stuff too. I've used a number of their programs for years, and find that they're fun, useful and reliable. Good Luck. Oh..there whois will tell you in about 2 seconds if a domain name is available, and who owns it and where to find them in another few seconds if it's taken. Several useful tools there.

Is 15 Model Stepping 9 GenuineIntel 1992Mhz compatible with Intel Pentium 4 processor?

All members of the "Model 15" family are Pentium 4s or based on a Pentium 4 core, so yes.

What is Socket 775?

Socket 775 (also known as LGA 775 or Socket T) is a socket for certain versions of the Intel Pentium 4, Celeron, Pentium D, Core Solo, Core Duo, Core 2 Duo, and Core 2 Quad. Unlike a traditional "socket", Socket 775 does not have any pinholes. instead, the pins are on the motherboard and reach up to contact the flat surface of the processor. Socket 775 was superseded by LGA 1156, but is still in common usage by most mainstream Core 2 Duo systems (as of January, 2010).

What are some names of CPU make and model?

Intel & AMD are main CPU makes.Models of each are given below :

Intel : P -IV, Intel DUal COre, Core 2 Duo, Quad Core etc.

AMD : Athlon, Phenom, Opteron etc.

What is the problem of i3 processor of Intel?

if i am not using laptop for games which processor will be best for me out amd 6 and i3. thanks

Can you have a list of companies manufacturing processors?

This is a list of companies who manufactured processors sometime or another. Some of these companies aren't manufacturing processors currently.

Though Intel, and AMD has a huge market share of microprocessors required for home/personal computers, Zilog stays in the background. Zilog manufactures processors for other equipments like remote controls, microwave ovens, mobile phones, PDA's, and similar.

PowerPC is a RISC architecture created by the 1991 Apple-IBM-Motorola alliance, known as AIM, from March 1994 until August 2006.

The following list is in alphabetical order:

1 AMD

2 ARM

3 Digital Equipment Corporation

4 Elbrus

5 Fairchild Semiconductor

6 Freescale Semiconductor (former Motorola)

7 Hewlett-Packard

8 IBM

9 Intel

10 MIPS Technologies

11 National Semiconductor

12 NEC

13 NXP (former Philips Semiconductors)

14 SPARC

15 Texas Instruments

16 VIA

17 Western Electric

18 Zilog

What does a fast clock do to the performance of the CPU?

Increasing the clock-speed of a processor increases its performance. There is so much more that goes into the overall performance of a processor (cache speed, cache size, hit / miss frequency on L1 and L2 cache, cycle recovery time on the cache, architecture, core efficiency, pipeline length, and northbridge frequency just to name a few) However, simply increasing a processor's clock speed WILL improve its performance, to an extent. Fast clock speeds send more calculations through the processor cores more frequently, thus leading to your increased performance. If it is pushed too high, a processor begins to see diminishing returns as more cache misses, overheating, and voltage inefficiency start setting in.

Always consider properly researching this matter before considering raising the clock speed of your processor.

Benefit of heat sinks in CPU?

It keeps your processor from melting. Do not run a PC without a heat sink on your processor. Processors can get to extremley high temperatures. The heat sink absorbs this heat and removes it using a fan.

Which one is better 3.0 ghz with 4M Pentium d or dual core 2.5 ghz with 2M?

Dual core E5200 (2.5GHz 2M) is better more than pentium d 925 (3GHz 4M), There is big different. E5200 performance equal double D925 performance.

Is 1800 MHz a good processor?

1.8Ghz is a perfectly good processor.....depending on what you are doing with the computer. If you are just using word processor type programs, surfing the web, doing email, etc. You will be fine with this. If you plan on playing any of the latest games you would benefit greatly from upping your processor speed.

CPU does not distinguish data and operation code explain?

As far as the bus interface is concerned, there is no real difference between data and instructions. Except for the S0 pin, an opcode fetch will look the same as a memory read. There is one extra clock cycle following an opcode fetch, which is used by the CPU to decode and process the opcode, but the bus does not care because there is no sequence initiation with ALE.

How do you identify processor age?

Right click My Computer, and figure out what type of processor you have first.

(Pentium III, Pentium 4, Athlon, Phenom, etc). This can narrow you down to a small year range that determines the literal age of your processor. For example, the Phenom II have a maximum age range of 2008-2012.

How old it is in terms of years of use? This is something nobody can tell you-- Keep track of this yourself or ask the previous owner of the processor.

What is askl?

A typing lesson in a special keyboarding class.

Why do use cisc and risc processor?

in cisc concept instruction set is complex but in case of risc the ins truction are reduced.

for example for mov operation many instruction are there as mov,mvi,sta,lda,lhld,shld,stax,ldax etc. but in case of risc only load and store(lda ,sta) are used for all as in case of ARM processors.
