What is register indirect addressing mode in 8086?
In the 8086 microprocessor, register indirect addressing mode is a method of accessing data in memory using a register to hold the address of the data. In this mode, the effective address of the operand is provided by a register, such as BX, SI, or DI. This allows for flexible data manipulation, as the contents of the register can be easily modified to point to different memory locations. This addressing mode is particularly useful for operations on arrays and data structures.
Memory address register is used to store?
memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk) memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk)
What do you call the register that organisations that hold personal data must register with?
Certificate Authority (CA)
What is an index counter in a microprocessor?
An index counter in a microprocessor is a register used to hold an index value that facilitates effective data access during operations, particularly in array processing and loop iterations. It allows the processor to dynamically calculate memory addresses by adding the index value to a base address, enabling efficient traversal through data structures. This feature enhances the speed and efficiency of data manipulation tasks in programs.
What is the function of TMP register of ALU in 8085 microprocessor?
The TMP register in the 8085 is used to hold temporary results of operations. You cannot directly manipulate it, so you should just pretend it is not there.
What is address register?
this is the memory that hold data temperaly and can be used in future
What is data register?
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
What do buffers and registers do?
Buffer register is a device uses to hold the information used during transfer.
What is capacity of register?
The capacity of a register refers to the amount of data it can hold, typically measured in bits or bytes. It determines how many binary values can be stored and processed at one time. For example, a 32-bit register can hold 32 bits of information, allowing it to represent 2^32 different values. The register's capacity is crucial in computing as it influences the performance and efficiency of data processing tasks.
What is the function of the microinstruction register?
It is a memory register inside the CPU. The function is to hold the current microinstruction. The microinstruction is the bits that drive the control signal and drive the data path.
What is memory data register?
The MAR is a special register in the sense that each time it is accessed from the outside, memory senses it and considers the new content of the MAR an address.
What does the microprocessor hold?
Lots of little transistors and gates
