When one instruction is in decode phase the CPU can process another instruction for fetch phase. The process of making the salad is then: bring the veggies from the fridge to the counter top; place some veggies on the chopping board according to the recipe; chop the veggies, possibly storing some partially chopped veggies temporarily on the corners of the cutting board; place all the veggies in the bowl to either put back in the fridge or put directly on the dinner table.
All data and instructions need to be entered into the computer system through the input unit. Related Papers. It stores the final results of processing before these results are released to an output device.
As we know there are millions of instruction a processor can complete within a second. It manages and coordinates all the units of the computer.
In our kitchen we have: a refrigerator where we store our vegetables for the salad; a counter where we place all of our veggies before putting them on the cutting board for chopping; a cutting board on the counter where we chop the vegetables; a recipe that details what veggies to chop; the corners of the cutting board are kept free for partially chopped piles of veggies that we intend to chop more or to mix with other partially chopped veggies.
Output Unit Output unit is responsible for transferring the processed data back to the outside world i. As the CPU finishes calculations about one employee, the data about the next employee is brought from secondary storage into memory and eventually into the registers.
Registers work under the direction of the control unit to accept, hold, and transfer instructions or data and perform arithmetic or logical comparisons at high speed.
What all does a Microprocessor comprise of? To process these instructions most of the time, it needs data. What do you understand by system clock?
