What are special purpose registers 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.

What are common general purpose and special purpose registers in the microprocessor?

The general purpose registers are used to store temporary data in the time of different operations in microprocessor. 8086 has eight general purpose registers. This is the accumulator. It is 16-bit registers, but it is divided into two 8-bit registers.

What is the difference between special and general purpose?

A general purpose computer is used for different programs for different functions. It can be used to do a lot of things. A speical-purpose computer is designed for special functions only. It is usually made to do one thing only.

What is register in microprocessor?

Registers are temporary storage locations inside the CPU that hold data and addresses. The register file is the component that contains all the general purpose registers of the microprocessor. A few CPUs also place special registers such as the PC and the status register in the register file.

What is general purpose register and its types?

General purpose registers are used to store temporary data within the microprocessor. There are 8 general purpose registers in 8086 microprocessor. It is of 16 bits and is divided into two 8-bit registers BH and BL to also perform 8-bit instructions. It is used to store the value of the offset.

What are the different types of registers in 8086 microprocessor?

Types of registers in the 8086 Microprocessor. 1 1) General Purpose Registers. The use of general-purpose registers is to store temporary data. While the instructions are executed in the control 2 2) Segment Registers. 3 3) Pointers and Index Registers. 4 4) Flag or Status Register.

How many bits are in a 32-bit Thumb-2 Register?

They are all 32 bits; the reset value is unpredictable. The R8 through R12 registers are also called high registers. They are accessible by all Thumb-2 instructions but not by all 16-bit Thumb instructions.

What is the difference between a high byte and low byte?

For ease in doing I/O, booleans are represented using one byte (not a single bit, as you might expect). High Bytes and Low Bytes. Java documentation sometimes uses the terms “low byte” and “high byte”. These are used when a data type uses more than one byte. The low byte is the byte that holds the least significant part of an integer.

What is the function of the status register in a processor?

It stores the offset address of the Destination. The Flag or Status register is a 16-bit register which contains 9 flags, and the remaining 7 bits are idle in this register. These flags tell about the status of the processor after any arithmetic or logical operation.
