What is the multiplier if your front side bus is 133 MHz and your processor runs as 2.53 GHz?

User Avatar

Asked by Poppymike71

Im guessing your multiplier would be around 19x or so, you could check this by entering your BIOS at startup and checking in there.

Ususally to enter the BIOS you hit one of the following:

-Esc

-F2

-F10

-F12

-Delete

One of these usually enters the setup.

How is a CPU different from a motherboard?

User Avatar

Asked by Wiki User

The Central Processing Unit (CPU) is the chip that actually performs the calculations that drive a computer. The motherboard is the board on which the CPU sits, and has the bus on which data is passed to the various input and output sources. Motherboards also usually contain slots for accessory cards (sometimes called daughterboards) such as a video card or network card.

The motherboard would be considered the nervous system, arteries and internal organs of a computer. The Central Processing Unit (CPU) would be considered the brain of a computer.

In a processor these are 120 instructions Bits needed to implement this instructions?

Asked by Ramyamaridi

Log2 260 is 8.022, so it would seem that 9 bits are required to handle 260 instructions. In practice, however, the opcode is a multiple of 8 bits, so most instructions are 8 bits, with a few being 16 bits.

Where is the cmos battery located in a Compaq Presario R3000 Laptop?

User Avatar

Asked by Wiki User

After taking apart the laptop (see instructions at

http://www.takeitapart.net/forum/index.php/topic,5.0.html) I found there is a CMOS battery under the keyboard, but it is soldered to the motherboard. This doesn't make it useful as a reset. I did not find a jumper or any other reset switch internal to the laptop. My research seems to suggest that holding the power button for 30 seconds is supposed to reset the CMOS. Unfortunately, that did not help in my case, but may for yours.

Is processor speed measured in GHz?

User Avatar

Asked by Wiki User

yes it is,

the term hertz represents repetitions per second, ie, a 3000 hertz processor makes 3000 calculations per second. the term hertz also refers to anything that follows a cycle a computer screen refreshes at about 70 hertz, or updates what you see 70 times a second

Absolutely false on both accounts!To answer the above question, "Is speed of CPU is measured in hertz?" - the answer is NO! The performance of a CPU is approximated by a multitude of different criteria including specific testing programs depending on what functionality of the CPU specifically needs to be tested and measured. This overall performance can widely vary depending on the testing program, all supporting hardware and the preconditions of the testing environment.

Regarding the original answer, these are all too common misconceptions these days! Unfortunately, you'll see ill advised reference to this throughout the periodicals, both on-line and off and even the marketing departments that desire to make the technical "jargon" more palatable - but not necessarily accurate.

The metric of "speed," which involves physical movement, has absolutely NOTHING to do with frequency measured in hertz. The two are NOT the same thing and are not interchangeable. A high school or college physics class will also prove this. You certainly don't get in your vehicle look at the speedometer and read 750 MHz or 3 GHz. Conversely, I've yet to see an actual laptop or desktop personal computer get up and physically move around the room or the house! It even seems silly!

How about some on-line proof? Check out the definitions on Wikipedia and elsewhere as cited below:

http://en.wikipedia.org/wiki/Speed

(Notice that nothing is stated about computing)

vs.

http://en.wikipedia.org/wiki/Hertz

http://en.wikipedia.org/wiki/Clock_rate

http://en.wikipedia.org/wiki/Frequency

Also reference the following:

Megahertz, for example, is defined as MHz, kilohertz as kHz and hertz as Hz. It is, in fact, ALWAYS a capital "H" to pay homage to the German Physicist Mr. Heinrich Hertz. Consider:

http://www.ideafinder.com/history/inventors/hertz.htm

or,

http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci214263,00.HTML

(Scroll down and notice the table) or,

http://tf.nist.gov/timefreq/general/glossary.htm

(Click on "M" or "J-K" - these folks should know the difference)

Want further proof? Take a look at, www.fcc.gov and note their frequency references. In addition, simply take a look at a stereo dial, clock radio or even your transistor radio and notice how the manufacturers abbreviate frequency. Notice that this has NOTHING to do with "speed." You don't tune your radio to a different "speed" nor do you head down the highway at 2 kHz or 3.2 GHz.Obviously, they're not interchangeable! The point is they're entirely different metrics.

In addition, the above claim that "a 3000 hertz processor makes 3000 calculations per second" is also false. Different processor manufacturers such as AMD, Cyrix(former), NEC, TI, Intel and others manipulate various calculations and instruction throughput differently. Depending on what specific instruction is being executed in the processor, it may take from a few cycles to several processor cycles to finish the execution of any particular instruction. Meaning, it is NOT a one-to-one ratio in relation to the clock rate! In other words, a 3 GHz microprocessor does NOT execute 3 Billion instructions (or calculations) per second!

What is the most common CPU speed?

User Avatar

Asked by Wiki User

This can be measured in a lot of ways. Typical for some categories listed below:

Typical home-end clock frequency is 3.0-3.6 GHz without any kind of overclocking.

Typical MiPS is averaging nearly 100,000 (This is getting phenominal!)

Processors are approaching the TFLOP level on the home-end as well.

IPC is 30~ for AMD and 50~ for Intel.

The last 3 are far more important in determining a processor's speed than the clock frequency.

What are the disadvantages of a 64-bit processor versus a 32-bit processor?

User Avatar

Asked by Wiki User

There aren't any real disadvantages to 64-bit processors. When running a 64-bit operating system, running a 16-bit application requires a context switch from 64-bit to 32-bit, from 32-bit down to 16-bit, and back to 32-bit and 64-bit. This creates a large performance penalty so in practice most 64-bit operating systems will not allow you to run 16-bit applications. This is unlikely to be a problem for most users, though.

There is one significant disadvantage of 64-bit processors when compared to 32-bit processors: minimum operation size for calculations. A 64-bit processor must do all integer calculations using a 64-bit wide register (that is, all integers must be represented as 64 bits in size). A 32-bit processor does all integer calculations in 32-bit sizes. While performing the actual calculation (e.g. adding two numbers) is neither faster nor slower under 64 vs 32 bit systems, the requirement to pull full 64-bit chunks from memory to do any calculation results in more memory "pressure" than a 32-bit processor.

The result of this is that for a system which does mostly smaller integer calculations (i.e integers which are 231 or small in size), a 32-bit system will have about HALF the memory bandwidth requirement of a 64-bit system. A memory latency is the the dominating factor in modern CPU performance (i.e. the time to get data from memory is far greater than the time to perform a calculation on that data), a 32-bit processor will perform noticeably faster doing such smaller calculations than a 64-bit processor.

A related disadvantage of a 64-bit CPU vs a 32-bit CPU is that the larger operational unit (word) size means that all pathways, registers, and memory units attached to a 64-bit CPU have to be about double the size as required in a 32-bit CPU. This results in about a 40% larger number of transistors required to implement a (roughly) equivalent 64-bit processor vs a 32-bit processor. This does not translate into a 40% higher cost, but does significantly increase production costs; it also significantly increases the thermal profile of the processor (i.e the larger number of transistors requires more power and produces more heat).

What is the difference between 32 bit microprocessor and 64 bit microprocessor?

User Avatar

Asked by Wiki User

The fundamental difference between a 32-bit and 64-bit microprocessor is what their names suggest: the size of the basic integer operations, also called the 'native' size of a CPU's calculations. The native size of a CPU determines a whole bunch of related characteristics.

For instance, all integer calculations are done using the native size; this matters in terms of performance for several reasons:

  • if you add two integers smaller than the native size, it requires only a single operation.
  • if you add two integers larger than the native size, you must perform 3 operations (add the upper values, add the lower values, then combine).

For instance, if you wanted to add two 20-bit numbers, on both the 32-bit CPU and 64-bit CPU it would require a single operation. However, if you wanted to add two 40-bit numbers, it would require only 1 operation on a 64-bit CPU, but 3 operations on a 32-bit CPU.

The native size of a CPU also determines things like the maximum addressable memory - thus, a 32-bit CPU can address up to 2^32 = 4GB of memory, while a 64-bit system can address up to 16 Exabytes. It also determines the minimum size of information that has to be processed - when fetching information from caches and memory, no operation can be done with information less than the native size. Thus, 64-bit CPUs are more demanding on memory subsystems, as they need to process information in 64-bit chunks, rather than 32-bit ones.

What cache memory is designed inside the CPU?

User Avatar

Asked by Wiki User

L1 and L2; Many years ago L1 was the only cache memory integrated into the CPU (processor) and L2 had to be added to the motherboard. Currently (as of year 2013), CPUs implement both L1 and L2 cache in the casing of the processor. Thus, processors (CPUs) ship with amounts of L2 cache independent for each processor core.
