What is the function of W and Z registers?

What is the function of W and Z registers?

They are exclusively used for the internal operation by the microprocessor. These registers are used either to store 8-bit of information in each W and Z registers or a 16-bit data in W, Z register pair with lower order 8-bits in Z and higher-order 8-bits in W register. Let us consider one example.

What is special purpose register in microprocessor?

A Special Function Register (or Special Purpose Register, or simply Special Register) is a register within a microprocessor, which controls or monitors various aspects of the microprocessor’s function.

Which register is used for temporary purpose?

Following is the list of some of the most common registers used in a basic computer:

Register	Symbol	Function
Program counter	PC	Holds address of the instruction
Temporary register	TR	Holds temporary data
Input register	INPR	Carries input character
Output register	OUTR	Carries output character

What is the use of shift register?

The shift registers are used for temporary data storage. The shift registers are also used for data transfer and data manipulation. The serial-in serial-out and parallel-in parallel-out shift registers are used to produce time delay to digital circuits.

What factors affect the speed of RAM?

The speed of your processor and the bus speed of the computer motherboard are the limiting factors on the speed of RAM installed in your computer. RAM upgrades are limited by the capability of the computer and the availability of expansion slots for adding RAM.

Will increasing RAM increase speed?

Generally, the faster the RAM, the faster the processing speed. With faster RAM, you increase the speed at which memory transfers information to other components. Meaning, your fast processor now has an equally fast way of talking to the other components, making your computer much more efficient.
