What is prefetch queue in 8086?

In the context of the 8086 microprocessor, the prefetch queue is a 6-byte high-speed queue that stores the next instruction to be executed. This helps improve performance by fetching instructions in advance and storing them in the queue. When the CPU is ready to execute the next instruction, it can quickly access it from the prefetch queue without having to wait for the instruction to be fetched from memory.

Explain 8086 flag register?

FLAGS REGISTER="h2headingh3"style="color:rgb(0,0,0);"name="flags_register">Flags Register - determines the current state of the processor. They are modified automatically by CPU after mathematical operations and allow one to determine the type of the result as well as determine conditions to transfer control to other parts of the program.

Generally you cannot access these registers directly.

  1. Carry Flag (CF) - this flag is set to 1 when there is an unsigned overflow. For example when you add bytes 255 + 1 (result is not in range 0...255). When there is no overflow this flag is set to 0.
  2. Parity Flag (PF) - this flag is set to 1 when there is even number of one bits in result, and to 0 when there is odd number of one bits.
  3. Auxiliary Flag (AF) - set to 1 when there is an unsigned overflow for low nibble (4 bits).
  4. Zero Flag (ZF) - set to 1 when result is zero. For non-zero result this flag is set to 0.
  5. Sign Flag (SF) - set to 1 when result is negative. When result is positive it is set to 0. (This flag takes the value of the most significant bit.)
  6. Trap Flag (TF) - Used for on-chip debugging.
  7. Interrupt enable Flag (IF) - when this flag is set to 1 CPU reacts to interrupts from external devices.
  8. Direction Flag (DF) - this flag is used by some instructions to process data chains, when this flag is set to 0 - the processing is done forward, when this flag is set to 1 the processing is done backward.
  9. Overflow Flag (OF) - set to 1 when there is a signed overflow. For example, when you add bytes 100 + 50 (result is not in range -128...127).

Cell that is found in tha basal layer that function as mechanoreceptor?

Merkel cells are found in the basal layer of the epidermis and function as mechanoreceptors responsible for detecting light touch and pressure on the skin. These specialized cells are connected to sensory nerve endings and play a role in sensory perception.

Impreza 94 wrx sti import with KMH clocks you want to change the clocks to the half digital clocks in the 99 upwards Imprezas 9000rpm 0 - 180 MPH Can this be done?

Yes, it is possible to retrofit newer digital clocks from a 1999 or newer Impreza into a 1994 WRX STI. However, it may require modifications to the wiring and dashboard to fit properly. Additionally, you may need to reprogram the new digital clocks to work with the existing systems in the older vehicle.

What is the Best Gaming Processor for Windows 10 laptop?

I play Online on Steam and Minecraft and one day I had bought the game Saints Row: Gat out of Hell and when I played it, it kept on saying Saints Row: Gat out of Hell has stopped working. What processor would you recommend for a small online gamer like me? How would I get it to work on a laptop, USB or charging port? Please include links and prices.

Physically how big was the Intel Pentium chip?

Great, I just saw it yesterday, I think it was about 5cm long and wide, ABOUT*.

What is the speed of the processor Intel Pentium Dual Core Inside?

The Intel quad core processor is super computer fast. It packs a 2GHz processing speed with a memory cache of 8M bytes and a CPU connection speed of 1.333 GHz. The Intel quad core became available in 2007.

Will a intel Dual core e3400 2.6ghz Processor play top end games?

This processor will play a big part in playing top end games yes but you will need a good graphics card also.

What is the difference between a Intel celeron processor 900 and a Intel Pentium duo core processor?

In general, Core 2 Duo are high performance processors, with two "CPUs on a chip" (that's the "core duo" meaning.

While Celeron processors are, generally, single core, low to medium performance, intended for budget to moderate mobile (laptop) use. Lower power, single CPU, less performance (but uses less battery power in that).

Note, having 2 cores is usually a plus, as the CPU has two 'brains' and can do two things at once. But some software is not two-core-aware, so in those cases the two cores wont really be used, and the chip will act like an older style single core.

Bottom line:

So if you need high performance, go for the Core 2 Duo (it will be at a higher price than Celeron, and will use more electrical current).

If performance is not a concern, but you need lower cost, or longer battery life, the Celeron may be a good choice.

How can you know your processor is 32 or 64 bit supported?

Go to the control panel and in the search bar in the top right type in system. Then in the results click 'show how much RAM is installed' in this window it will show you what type of processor you have.

Is an Intel Atom Processor good?

The Intel Atom (when paired with an appropriate chipset) is very good about not consuming a lot of power or generating much heat. Performance-wise, however, it falls far behind most modern processors. it has been compared to a 2.4 Ghz Pentium 4 at accomplishing most tasks.

Here is my personal experience with the Atom N270 cpu...

I purchased an eMachines em250 netbook which includes the Atom CPU. It came with Windo*s 7 starter (which I upgraded to Home Premium), and used for several months before switching to Ylmf-OS Linux. The computer does everything I need it to do, and performs quite well! The little CPU (with the Intel 945G based graphics) can handle 3D games fairly well, for example Freespace, Babylon 5:IFH, GLTron, and The Babylon Project. Web browsing is quite speedy, DVD playback from my external drive is smooth, as is video playback from any of the Tube sites, and Hulu. The Hulu stand alone application and Windows Media Center work OK, though the interface seems a little bit slow to respond at times.

Once I made the switch to Linux, I found that the CPU seemed to perform DRAMATICALLY better. Overall system responsiveness has improved by a factor of 4 times. The computer is hooked up to an external 24 inch HD display, and I can watch a movie on one screen while web surfing on the other one. Overall, I would rate the Atom as a very good value as CPUs go.
