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.

Give you 5 examples of microprocessors?
This term stands for a general purpose digital computer consisting of the CPU (Central Processing Unit). A microprocessor usually contains an ALU (Arithmetic Logical Unit.
In the CPU , majority of the operations and tasks assigned to the microprocessor are completed. In the ALU , only arithmetic ( addition , subtraction etc.) and logical ( And, Or , Not etc.) are taken care of.
The prime use of a microprocessor is to read data, perform extensive calculations on that data and store those calculations in a mass storage device or display the results for human eye. This sits on the motherboard of each PC ( Personal Computer). The motherboard stands for the card in the PC that controls almost all the other peripherals. Examples of microprocessors are the Intel 8085 ( one of the first microprocessors), P1 family, P2 and now the P3 family from Intel Inc.
Is sending an Email a function of the CPU?
No. It is a function of an application (SMTP is an e-mail sending protocol within these applications).
What is the timing diagram for CALL instruction?
18 T States.
6T States for Opcode fetch.
3 *2 T States for memory write(PC pushed to stack)
3*2 T States for memory read (New value of PC fetched from memory).
Good Luck!!!
Can Intel R G33 G31 Express Chipset Family run pixel shader 3?
Yes it can . I have the Intel(R) G33/G31 Express Chipset Family too and the game ! The game runs great !
Game : 60-70 Fps
Sry for my English :(
Can motherboards running Intel core 2 duo also run core i3?
No. Core 2 is on a different socket type. The i3 will not fit into the core 2 socket, and vice versa.
What are the factors affecting CPU performance?
There are many factors.
1. Clock frequency
2. Memory bandwidth
3. L2/L3 cache size
4. Instruction per cycle
5. number of CPU cores.
How does CPU generate logical address?
Lets take the scenario of CPU <-> MMU (memory management unit) <-> Physical Memory.
CPU generates the logical address as Page number + Page offset.
Of course this address will point to some physical address.
Page number is for the index in page table (for base address).
The base address + offset is sent to MMU which is mapped to the corresponding physical page.
Conditional call and unconditional call all condition of 8085 microprocessor?
Calls Which are based on conditions like flag status are called conditional flags
ex:cc(Call if carry)
cz(Call if zero)
Calls Which are independent of any kind of conditions, are called unconditional call
Ex:Call 2030
How do you draw timing diagram of ADD M instruction?
I'm assuming that you mean "Add the contents of memory to an accumulator and place the sum back in the accumulator".
First, the address of the memory location needs to be placed on the address bus and the control lines to memory need to be driven in such a way as to tell the memory that a write operation has been requested (usually enabling OE and synchronizing with a clock).
Next (one or more clock cycles later depending on the type of memory being used), the data is returned from the memory. It must then be routed to the ALU.
The value in the accumulator must also be moved to the ALU and can be performed in either the first or second CPU cycle, depending on the internal architecture of the CPU. It is probably safest to do this in the first cycle.
Next the ALU must perform the addition instruction (third CPU cycle).
Finally, in the fourth cycle, the result can be moved from the ALU back to the accumulator.
What is the purpose of a CPU test?
A CPU test or a "stress test" is where a computer is vigorously tested to find out how stable the computer is. It can determine the breaking points and safe usage limits of the computer, as well as how or why a computer system fails.
Difference bw macros and procedure in microprocessor?
A procedure, also sometimes called a function, routine or subroutine, is a section of code that performs a certain task which is used repeatedly within an application. For example, a procedure might sort the names in a list of names alphabetically. An application may hold a list of names of countries, cities, and people, and may be designed to use the same procedure to sort all three lists of names. It is characteristic for a procedure that the procedure's code exists once within the application. Executing the procedure requires that the processor "jumps" to the procedure and, upon completion, returns to the location following the "jump." Because this "jump" supports the means to return from the procedure, it is typically called a call, but terminology varies.
A macro typically contains a smaller section of code. Just like with a procedure, the macro supports a notion of "write once, use more than once." Unlike a procedure, however, a main thread of execution does not call the code and return from it. Instead, the macro inserts its code into the main code, and this expands into as many location as it is used.
For example, a macro could be a simple expression to obtain the number of names in the list of names. In this hypothetical example, this is is easily obtained and doesn't justify the overhead of call and return, and the application may benefit from the higher execution speed (at the price of an increased memory footprint).
What is the best safety uses of memory?
cache memory it com up with processor p4 and more with max 2 mb
it is of 3 the L1 L2 L3:- L1 AND L2 are in processr and L3 is in mother bord Shorter version: It increases memory space in the CPU.
There are onlu TWO types of processors. These are:
1. Intel 2. AMD
And of course there are some different processors that do different things, even though they are the same brand name. A Macintosh processor is different from a Windows processor, because the Macintosh processor (my opinion) is more powerful. There are also different processors for different for different types of technology. A PDA would have 64-bit processor, but they are under Intel. The United States is the only country that makes processors, both Intel and AMD. The specific types of processors are:
Intel: (These are the current ones that most people have) 1. Pentium Pro 2. Pentium II 3. Celeron (Pentium Based But More Powerful) 4. Pentium II Xeon 5. Pentium III 6. Pentium II and III Xeon 7. Celeron (New Generation, Pentium III Based) 8. Pentium 4 (Most common) 9. Pentium M 10. Intel Core 11. Dual Core Xeon LV 12. Intel Pentium Dual Core 13. Intel Core 2 14. Pentium Duo 15. Pentium Dual Core 16. Core 2 Quad 16. (Newest) Intel Pentuim 2 Dual Core Processor
Amd: (The Current One's) 1. AMD Athlon 2. AMD Athlon 64 3. AMD Athlon X2 4. AMD Athlon Xp 5. AMD Duron 6. AMD Sempron 7. AMD Turion 8. AMD Opteron 9. AMD Phenom 1.
The PowerPC processor (formerly used in some MacIntosh computers) is used in the Xbox 360, the Wii, and the PlayStation 3.
The most popular 32 bit processor (in terms of units sold) is the ARM processor.
