What is 8087 NDP Co-processor?

User Avatar

Asked by Wiki User

The 8087 NDP (Numeric Data Processor) is a coprocessor designed by Intel to work alongside the 8086 and 8088 microprocessors, which were prevalent in early personal computers. The NDP was introduced in 1980, and it provided hardware support for floating-point arithmetic operations.

Floating-point arithmetic is used for calculations involving decimal numbers, which are common in scientific and engineering applications, as well as in graphics and multimedia processing. The 8087 offloaded these calculations from the main processor, significantly speeding up numeric computation tasks.

The 8087 performed operations such as addition, subtraction, multiplication, division, and square roots much faster than software implementations, which relied on the main processor's instructions. This acceleration was particularly important in fields like computer-aided design (CAD), numerical analysis, and gaming.

Later, Intel developed more advanced coprocessors, such as the 80287 and 80387, which offered improved performance and additional features. However, with the advancement of microprocessor technology, dedicated floating-point coprocessors became less common as modern CPUs integrated floating-point units directly into their designs.

How does one Burp on command?

Asked by Wiki User

To burp on command, you can try swallowing air to build up gas in your stomach and then releasing it by contracting your diaphragm. Some people find success by drinking a carbonated beverage or swallowing air and then forcing it back up by using their throat muscles. Practice and patience may be needed to master the technique.

Highest priority interrupt in micro processor?

User Avatar

Asked by Wiki User

The highest priority interrupt in a microprocessor is usually the reset interrupt. When a reset occurs, the microprocessor is forced to stop its current operations and begin executing the reset routine. This is critical for initializing the processor and setting it to a known state before starting normal operations.

What are segment registers?

User Avatar

Asked by Wiki User

In the x86 processor architecture, memory addresses are specified in two parts called the segment and the offset. One usually thinks of the segment as specifying the beginning of a block of memory allocated by the system and the offset as an index into it. Segment values are stored in the segment registers. There are four or more segment registers: CS contains the segment of the current instruction (IP is the offset), SS contains the stack segment (SP is the offset), DS is the segment used by default for most data operations, ES (and, in more recent processors, FS and GS) is an extra segment register. Most memory operations accept a segment override prefix that allows use of a segment register other than the default one.

What is the difference between microprocessor and micro computer?

Asked by Wiki User

A microprocessor is a processing unit that carries out instructions and tasks within a computer system. On the other hand, a microcomputer refers to a complete computer system that typically includes a microprocessor, memory, input/output devices, and storage. In essence, the microprocessor is the central processing unit within a microcomputer.

Why do we ever build just microprocessor Why not just build micro controllers that contains everything on chip?

User Avatar

Asked by Wiki User

Microprocessors and microcontrollers serve different purposes. Microprocessors are better suited for more complex tasks that require higher processing power and flexibility, while microcontrollers are designed for simpler tasks that require lower processing power and are cost-effective. By using separate components, designers have the flexibility to choose the best option for their specific requirements.

From the Wikipedia article, it looks like they would operate at 3, 5, or 6 megahertz (MHz), or maybe it's 3.5 MHz and 6 MHz (they use 3,5 - not sure if that's a European decimal point or a comma)

What does a data encoder do?

User Avatar

Asked by Wiki User

1. Any program, circuit or algorithm which encodes.

Example usages: "MPEG encoder", "NTSC encoder", "RealAudio encoder".

2. A sensor or transducer for converting rotary motion or position to a series of electronic pulses.

An encoder is a device used to change a signal (such as a bitstream) or data into a code. The code may serve any of a number of purposes such as compressing information for transmission or storage, encrypting or adding redundancies to the input code, or translating from one code to another. This is usually done by means of a programmed algorithm, especially if any part is digital, while most analog encoding is done with analog circuitry.

* A compressor is used to encode data into a smaller form.

* A multiplexer combines multiple inputs into one output.

* A rotary encoder is a sensor, transducer for converting rotary motion or position to a code of electronic pulses.

* A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal, which can then be decoded into position by a digital readout (DRO). Motion can be determined by change in position over time. Linear encoder technologies include capacitive, inductive, eddy current, magnetic, and optical. Optical technologies include shadow, self imaging and interferometric. Linear encoders are used in metrology instruments and high precision machining tools ranging from digital calipers to coordinate measuring machines.

In digital audio technology, an encoder is a program that converts an audio WAV file into an MP3 file, a highly-compressed sound file that preserves the quality of a CD recording. (The program that gets the sound selection from a CD and stores it as a WAV file on a hard drive is called a ripper.) An MP3 encoder compresses the WAV file so that it is about one-twelfth the size of the original digital sound file. The quality is maintained by an algorithm that optimizes for audio perception, losing data that will not contribute to perception. The program that plays the MP3 file is called a player. Some audio products provide all three programs together as a package.

In computer technology, encoding is the process of putting a sequence of characters into a special format for transmission or storage purposes.

How do you calculate your computer system speed?

User Avatar

Asked by Wiki User

Speed matter when it comes to computing. With new computers costing upward of $1,500, you will naturally want to ensure that you are getting what you paid for. Computer speed can be calculated through a number of different ways, but all of these methods can provide a reasonable approximation of how fast your computer is running. Many of these methods can also let you know how quickly your computer is running when compared to similar models, letting you know whether you found a bargain or a lemon.

steps

1. Locate the basic speed of your computer by right clicking on the "My Computer" icon and selecting the option for 'Properties.' This will list the processor speed and onboard memory amounts of your machine, allowing you to see whether they match up with the promised manufacturer specs. Additionally, if you are running either Windows Vista or Windows 7, the screen will contain a general performance rating, allowing you to ascertain how capable your computer is of running the operating system.

2. Download the run the Sandra test (linked below in Resources) to determine how fast your computer's subsystems are when compared against similar models. You will be able to judge your computer's memory speed, hard drive speed, network speed, processing speed and all other salient characteristics of your machine. It will also allow you to compare your computer's results against the results of similarly equipped computer. The test itself is free to download, making it a bargain when it comes to calculating computer speed.

3. Use the SuperPI program (linked below in Resources) to calculate your overall processing speed compared against the most powerful computers in the world. The SuperPI program will calculate the number PI to 4,294,960,000 decimal digits, which will take most computers a fairly substantial amount of time.

RISC stands for Reduced Instruction Set Computer. The design strategy of a RISC processor includes limiting the number of instructions. This does not mean that ALL RISC processors have less instructions than ALL CISC processors, but in general, they do.

What is the speed of the CPU meausured in?

User Avatar

Asked by Wiki User

There is no one measurement of CPU speed. Different CPU's may perform differently on various tasks. For instance, you might find something like this:

CPU 'A' runs program 1 in 5 seconds

CPU 'A' runs program 2 in 4 seconds

CPU 'B' runs program 1 in 4 seconds

CPU 'B' runs program 2 in 7 seconds.

It may appear that CPU 'A' is faster over all in this instance... But it may be the case that program '1' is run 100 times more often than program '2' which would make CPU 'B' the faster one.

There are some very complicated ways of actually figuring out which is faster, but that would require looking deeply into its architecture. And the problems your CPU will be working on. The best way to get an idea about what processor is actually faster is to look at sites that offer processor benchmarks such as TomsHardware.com. Otherwise you will be looking into MIPS (Millions of instructions per second.) along with GHz, and today you will even need to see how much a parallel architecture will speed up your program.

Don't let anyone tell you there is one simple number that will tell you how fast a computer is. Many people have tried to use GHz as a measure in the past, but this just isn't valid on its own. If you have 20 pipelines stages, your throughput will be lower for the same clockrate. The only time clock rates can be compared is between processors with the same architecture. (And I don't just mean x86 here!) They need to be developed with the same caches, branch prediction etc.

What is the normal temp for a CPU?

The temperature at the CPU varies from CPU to CPU, the best thing to do is to find your CPU model at Intel or AMD (more likely) look at the specs. and should tell you the maximum temperature it can handle

How is CPU speed calculated?

User Avatar

Asked by Wiki User

CPU speed is calculated off of the Front Side Bus (FSB) speed and the CPU Multiplier. Don't confuse HyperTransport (HT) or Quad Data Rate (QDR, aka Quad Pumping) with FSB. HyperTransport and QDR have "replaced" FSB, but they too rely on the FSB. FSB was formerly used as a transport medium for data between the processor, memory and northbridge chipset and is now used more just as a reference clock frequency.

FSB * Multiplier = CPU Speed

For example, my Sempron 3400+ runs at 2.0 GHz with an 800MHz HyperTransport bus. It runs on a 200 MHz FSB bus and has a multiplier of 10. The HyperTransport multiplier is 4.

200 MHz FSB * 10x Multiplier = 2,000 MHz CPU

200 MHz FSB * 8x HT Multiplier = 800 MHz HyperTransport bus

List three factors need to consider when upgrading processor?

User Avatar

Asked by Wiki User

Clock speed, MIPS (if such information is provided), how many cores, and socket.

But all depends on what you really want to use it for. You won't need more than dual-core or a quad-core if you're just gaming (most programs and games don't use more than one).

However if you're into the content-creation industry (video editing/producing, YouTube or other video sites) or if you run a business that requires business-grade servers, then more cores will definitely help with rendering times and load balancing.

What is level 1 2 and 3 cache?

User Avatar

Asked by Wiki User

; L3 Cache (Level 3 Cache) This type of cache is becoming more prevalent as microprocessor manufacturers ship more processors with L1 and L2 cache built into the processor. L3 cache is then the extra cache that sits on the motherboard between the processor and main memory, since the processor already contains L1 and L2 cache. Some processors are starting to ship with L3 cache built-in as well to speed up memory operations further. In those cases the L3 cache often sits on a separate area of the die, not built directly into the chip core.
