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.

Similarites between a microcontroller and a microprocessor?

Microcontroller = (microprocessor+memory+peripherals) on a single chip

Basic steps used by the processor in instruction processing are?

1.Fetch the most instructions from memory.

2.Read an apparend if required by the instruction.(Apparend is a quantity to be operated as directed by its associated instruction.)

3.Execute the instruction.(Do what the instruction says.)

4.Write the result backe into memory.(If required by instruction.)

Is phene ALU CHURA?

yesss because Derek is da son of phene dats how dey both have ALU CHURA'S

How do you reduce your clock speed without turning your computer on. I changed it in the BIOS and now it wont allow me to turn on the computer?

You will need to open the cover to your PC and there should be a jumper labelled CLEAR CMOS you need to either move the black jumper accross and back again or if it is just two pins, short the pins with something momentarily. DO THIS WITH THE COMPUTER OFF.

Failing this you can remove the battery (looks like a ten pence piece) leave it a few minutes and reinsert it. Then boot up.

Where is the CPUs instruction set stored?

The CPU's instruction set is not stored anywhere. Rather, it is an integral part of the silicon that the CPU is made out of. The "instruction set" is actually a metaphor used to describe the different effects of charges at different points in the CPU. Just because I call a certain operation "add" doesn't mean anything to the CPU. Charges are applied and due to the way they are applied, different transistors open and close, providing different effects.

What are the differences in the properties between the silicon substrate and the oxide layer?

Silicon Substrate

Silicon substrates are mainly used for power semiconductors in automotive, electronics and HF front-end pa. silicon that can be fused with other materials, such as thermal oxide and or silicon nitrite.

Oxide Layer

An oxide layer is a thin layer or coating of an oxide, such as iron oxide. Such a coating may be protective, decorative or functional. It is a passivizing layer on the surface of the metal, preventing further corrosion.

What is arm9 risc 32-bit processor?

Its exactly what is says on the tin. A 32-bit processor that uses the ARM9 architecture.

Why the 16 bit 8085 microprocessor is not possible?

The 8085 was replaced with the 8086/8088. As such, there is no 16 bit version of the 8085.

What is the maxium you can upgrade an averatec 3250 laptop as for the c.p.u.harddrive and memory if possible?

RAM on a 3250 can be upgraded to one gig. It's a single slot, however, which means you'll have to buy a one-gig chip, rather than adding to what you already have:

1 gb PC2700 - DDR - 333MHz - SODIMM - Un-Buffered - Non-Parity

Why 1 mb is equal to 1024 kb while 1 kg is equal to 1000g?

you are completely right, but mathematical theory is not always true in practice: the difference of 24 you discovered is due to a small error that your computer experiences when it runs its activities. first of all, the 24 bytes more are arranged in 6 components of 4 bytes each: 24 = 6 x 4 then, all information is stored in blocks of 4 kb, so in each block you have a total of 24 x 4 = 96 bytes more. 96 = 100 - 4, and these 4 bytes less constitute a precise measure of the error your computer experiences whenever it handles one block of information: it lacks one 4 bytes component! nevertheless, 4 bytes over 4 kb is only 0.1%, so your calculations still can be considered pretty reliable. everybody hopes that in the future man will be able to produce artificial machines able to do perfect calculations, but up to now it has not yet been possible. so: continue investigating!

What is the function of alu?

ALU

Short for Arithmetic Logic Unit, ALU is one of the many components within a computer processor. The ALU performs mathematical, logical, and decision operations in a computer and is the final processing performed by the processor. After the information has been processed by the ALU, it is sent to the computer memory.

In some computer processors, the ALU is divided into two distinct parts, the AU and the LU. The AU performs the arithmetic operations and the LU performs the logical operations.

What two operations are performed by alu?

The Arithmetic Logic Unit (ALU) performs two primary operations: arithmetic operations and logical operations. Arithmetic operations include addition, subtraction, multiplication, and division, while logical operations involve comparisons and Boolean operations such as AND, OR, and NOT. These operations are fundamental for processing data and performing calculations within a computer's CPU.

Is your processor 64-bit?

If you are using Linux then you can use uname command, which prints system information including kernel version and whether kernel is 32 bit or 64 bit. You can also use less /proc/cpuinfo command determine if it is 64 bit CPU or not.

Example: $ uname -a

How many MB is equal to 177000 kb?

One Mb is equal to 1000 kbs.... so 117 Megabytes (Mbs) or .117 Gigabytes(Gbs)

What is the purpose of instruction pipelining?

An instruction pipeline is a technique used in the design of computers and other digital electronic devices to increase their instruction throughput (the number of instructions that can be executed in a unit of time).

What does 1.5 GHz mean?

It means 1.5 Gigahertz. This refers to the number of times the CPU clock ticks per second. So in this case, 1.5 Gigahertz would mean that the clock would cycle 1,500,000,000 times per second.

The NTVDM CPU has encountered an illegal instruction?

I have a problem on my PC,when running the BorlandC program. It appears like this

Borland C++ for DOS

The NTVDM CPU has encountered an illegal instruction.

CS:c000 IP:ed31 OP:8d e0 30 8e Choose 'close 'to terminate the aplication

Please if someone of you solve such problems help me.Thanks a lot.

New and Perfect Answer:

I have tried it and it really works 100% surity.

download DosBox for windows and then open it . in it type the following code:

z:\> mount c:\TC

z:\>c:

c:\>cd BIN

c:\BIN>tc

the tc ide will appear in which set the Options->Directories : change directory path to C:\Include and C:\Lib instead of C:\TC\Include and C:\TC\Lib and click on OK.

now when using graphics in initgraph(&g,&h,"C:\\BGI"); here C:\\BGI is used instead of C:\\TC\\BGI.

You will have to always make above settings whenever dosbox will be used.

And also now is you compile and run your program through Ctrl + F9 and if dosbox closes then you should use F4 or F8 keys. F8 line by line compiling and F4 compiles till cursor position , if F4 is used then place cursor position on the closegraph() code and after seeing the output you can use Ctrl+F9 or F8 function keys to complete the program execution.

and + if you are not working with graphics.h then there is a much easy solution for this find tc.exe go to it's property(not shortcut of TC.exe) in property there should be a tap called "screen" .. check "usage" to "window" rather than "full screen" .. :) .. now start it .. it will open in window mode .. then press ALT + Enter to get full screen .. it works for all programming but with graphics.h ..it may or may not work :(
