What is register and different types of register?
Following is the list of some of the most common registers used in a basic computer:
| Register | Symbol | Function |
|---|---|---|
| Address register | AR | Holds address for the memory |
| Accumulator | AC | Processor register |
| Instruction register | IR | Holds instruction code |
| Program counter | PC | Holds address of the instruction |
Which are primarily two types of register?
There are primarily two types of register: general purpose register. dedicated register.
What are registers in 8085 microprocessor?
The 8085 has six general-purpose registers to store 8-bit data; these are identified as- B, C, D, E, H, and L. These can be combined as register pairs – BC, DE, and HL, to perform some 16-bit operation. These registers are used to store or copy temporary data, by using instructions, during the execution of the program.
What are the four types of registers?
Different Types of Registers
- MAR Register. The full form of MAR is the memory address register.
- MDR. The full form of MDR register is a memory data register.
- MBR. The full form of MBR is the memory buffer register.
- PC. The full form of PC is the program counter register.
- Accumulator.
- Index Register.
- Instruction Register.
How many types of registers are there in 8085 microprocessor?
The 8085 has six general – purpose registers to store 8-bit data; these are identified as B, C, D, E, H and L as shown in the figure.
What is a processor register?
Processor register. In computer architecture, a processor register is a quickly accessible location available to a computer’s central processing unit (CPU). Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only.
What is a register in computer?
A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction.
What is a data register?
data register. A register used in microcomputers to temporarily store data being transmitted to or from a peripheral device.
