Types of Registers in 8086 Microprocessor
Registers are storage blocks for temporary storage in microprocessors. They hold important information temporarily while the microprocessor works on it. Think of registers as tiny boxes where the microprocessor keeps things it needs to use right away.
In other words, one may also say that registers are like the memory of a computer’s brain, storing tiny bits of information that the microprocessor needs to work with quickly.
In 8086 microprocessor, the registers are categorized under following four types:
- General Purpose Registers
- Segment Registers
- Special Purpose Registers
- Flag Registers
These different types of registers of 8086 microprocessor are briefly discussed below.
Types of Registers in 8086 Microprocessor
A microprocessor is a register-based clock-driven digital device that is used for data processing. It is a multipurpose device that is capable of producing outputs when provided binary data as input. In computers, the microprocessor is like the brain, handling tasks and calculations. Inside the microprocessor are tiny storage units called registers.
An 8086 microprocessor is 40 pin microprocessor, which was designed by INTEL in 1976. It is a 16-bit microprocessor that has 20 address lines and provides storage up to 1MB. It provides two modes of operation:
- Minimum Mode, suitable for systems having multiple processors
- Maximum Mode, suitable for systems having single processors.
