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.

How do you check CPU MIPS in PC?

The MIPS (Millions of Instructions Per Second) is not actually a 'static' set like your CPU's default frequency or similar settings. It is a measurement of performance.

You will need to use a benchmarking tool, such as SiSoft SANDRA or PiFast to benchmark it.

Can Sims 3 run on 1.8 Ghz dual core?

It depends on the processor, if its a dual core or quad, possibly, it depends if the Sims 3 is a single or multi threaded application, which i don't now, and the processor type

How do you tell if a processor is overclocked?

Check the CPU specifications with CPU id (you can download it from http://www.cpuid.com/) and compare frequenzy, fsb, memory speed etc with the retailers specifications

Example:

http://www.komplett.se/ (swedish)

http://www.amd.com/gb-UK/Processors/0,,30_292_8350,00.HTML

http://www.Intel.com/

or try Google, type in "amd 3200 Venice + review"....

if the CPU turns out to be overclocked you can reset it by reseting BIOS (Google "how to reset bios"). some motherboards have a small button for resetting bios and others don't so if it doesn't you must remove the CMOS battery (looks like a car key battery)

please note that static electricity can destroy electonic components in the computer...

What is DEN in 8086 in microprocessor?

Data enable, signals that bus lines are being used to transfer data

Suppose you are writing a large software package for a data acquisition application the data is to be acquired by a memory mapped device which connects to the system bus and interrupts the CPU anytime?

Sounds like a good solution.
Personally, I'd write it in UNIX, Linux or some other interrupt driven operating system. I'd hang a read or otherwise set a wait flag for the interrupt, then flush the buffer.
If the memory mapped device device is well established, with some nice protocols, it's probably setting the interrupt flag when data is ready. If that's the case, when you receive the interrupt, just read the data. Unfortunately, you may have a device that isn't quite so mature, in which case you'd need to trap each byte. If that's the case, you'll need to find a way to populate the buffer and validate the data stream.

Which is important the motherboard or CPU?

Both are vital components of your computer without a motherboard their would be no possible way to run your computer since it like the "brain" of the computer. Without a CPU, your computer would not be able to process anything, it might not even start up.

What is QPI speed?

qpi is a new type of bus for cpu's, replacing the traditional front side bus. it stands for quick path interconnect

What kinds of computers is the PowerPC compatible with?

PowerPC processors can only be used in computers or peripherals that were originally designed to run them. Some computers that have PowerPC or PowerPC-based processors include:

* Macs made between 1994 and 2005 * The Pegasos and Pegasos II (a desktop computer designed for operating system developers) * the EFIKA (a motherboard for embedded systems) * The GameCube uses a custom PowerPC-compatible CPU * The Wii uses a custom PowerPC-compatile CPU based on the one in the GameCube * The Xbox 360 uses a triple-core PowerPC-based CPU * The PS3 uses the Cell processor, which is based upon and mostly compatible with PowerPC processors. * The AmigaOne, a computer designed to be the successor to the 68k-based Amigas.


Explain one limitation of a 16-bit processor to a 64-bit processor?

One limitation of a 16 bit processor, compared to a 64 bit processor, is computing speed.

A 16 bit process can process 2 bytes (8 bits = 1 byte) of information per clock cycle.

While a 64 bit processor can process 8 bytes of information per clock cycle, making the 64 bit processor four times faster than a 16 bit processor.

What is type of register in CPU?

types of register in the CPU are bits and chips

What is Bit Slice Processor?

Bit slicing is a technique for constructing a processor from modules of smaller bit width. Each of these components processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a particular software design. Bit slice processors usually consist of an arithmetic logic unit (ALU) of 1, 2, 4 or 8 bits and control lines (including carry or overflow signals that are internal to the processor in non-bitsliced designs). For example, two 4-bit ALUs could be arranged side by side, with control lines between them, to form an 8-bit,16-bit,32-bit words (so the designer can add as many slices he wants to make it to manipulate longer words lengths). A microsequencer or Control ROM would be used to execute logic to provide data and control signals to regulate function of the component ALUs. Examples of bit-slice microprocessor modules can be seen in the Intel 3000 family, the AMD's Am2900 family the National Semiconductor IMP-16 and IMP-8 family, and the 74181.

How can the installation of RAM affect the clock speed of the processor?

It doesn't; the clock speed of your RAM is governed by your Front Side Bus clock frequency.

With more RAM installed your PC will run faster, but the CPU clock speed is not responsible for this.

Actually,installing RAM would never effect the processor speed .AS there is a clock generator(eg:8284-A which was being used in the 8086 processor long back) which determines the clock of of the processor which in term is responsible for the speed of the processor.for eg:Every read or write operation takes 4 clock cycle for instance & if ur processor's clock speed is 1 mega hZ frequency i.e a clock pulse is of 1 micro seconds i.e ur write operation will take 4 micro sec & suppose my processors's clock speed is 2 mega hZ frequency i.e a clock pulse is of 0.5 micro seconds i.e my write operation will take only 2 micro second.

now what actually RAm is? it is just a temporary memmory provided to the prcessor for communication. processor hardly communicates with the hard disk. whatever data is required by processor it is first transfered to the RAm first and processor retrives it from there.so if u have larger RAm large data can be stored in it & would not want it regularly from the hard disk. there r a lot of other things involved like the type of architecture and cache memmory.however ,i hope i would have answered to this question.

Does a ribbon cable connect to the CPU?

No. It connects to the motherboard at one end, and a drive or device on the other.

Can the dell optiplex 780 support an Intel i7 processor?

No sorry the Dell Optiplex 780 can't support a i7, it would have to be a 1155, 1156, 1366 socket compatible motherboard, but your options would be a Intel Core 2 Quad like a Q6700, upwards. Your Dell has a 775 socket.
