What are the 5 types of registers?
Some of the commonly used registers are:
- AC ( accumulator )
- DR ( Data registers )
- AR ( Address registers )
- PC ( Program counter )
- MDR ( Memory data registers )
- IR ( index registers )
- MBR ( Memory buffer registers )
What is register explain different types of register?
Among of the some Mostly used Registers named as AC or Accumulator, Data Register or DR, the AR or Address Register, program counter (PC), Memory Data Register (MDR) ,Index register,Memory Buffer Register. These Registers are used for performing the various Operations.
How many types of registers are used in computer?
There are two types of registering in the memory data register. When the data is fetched from the memory and copied to the MDR the information is stored in one single direction and the data is written by other CPU registers that store data in computer memory.
What are the functions of CPU registers?
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 are 3 types of registers in CPU?
memory address register (MAR) memory data register (MDR) current instruction register (CIR)
What is the function of shift register?
Shift registers are commonly used in converters that translate parallel data to serial data, or vice-versa. Shift registers can also function as delay circuits and digital pulse extenders.
What are the 4 registers in a CPU?
Different processors have different numbers of registers for different purposes, but most have some, or all, of the following:
- program counter.
- memory address register (MAR)
- memory data register (MDR)
- current instruction register (CIR)
- accumulator (ACC)
How many registers are there?
The CPU has 8 general-purpose registers, each capable of storing 32-digit binary numbers.In addition to 32-bit data, they can also store 16- or 8-bit data. This is illustrated in Figure 4.2.
What are the 4 types of registers?
There are different types of registers, including memory address registers, memory buffer registers, input output address registers, and input output buffer registers and shift registers.
What is the function of ALU?
The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data.
What is the function of index register?
An index register is a circuit that receives, stores, and outputs instruction-changing codes in a computer. This circuit is also called an address register or a register of modifications. A register is a data-holding place in a computer processor.
What are the 5 main CPU registers?
arithmetic logic unit (ALU) registers.

What is ALU function?
function in digital computer
The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data. The control unit fetches data and instructions from memory and… In digital computer: Functional elements.
What is SISO register?
The SISO shift register is one of the simplest of the four configurations as it has only three connections, the serial input (SI) which determines what enters the left hand flip-flop, the serial output (SO) which is taken from the output of the right hand flip-flop and the sequencing clock signal (Clk).
What is SIPO shift register?
Serial-In Parallel-Out shift Register (SIPO) –
The shift register, which allows serial input (one bit after the other through a single data line) and produces a parallel output is known as Serial-In Parallel-Out shift register.
What are the 14 registers in 8086?
The 8086 has 14 16 bits registers. AX, BX, CX, DX, SI, DI, BP, SP, CS, DS, SS, ES, IP and the flags register.
Where are the registers in a CPU?
Processor registers are normally at the top of the memory hierarchy, and provide the fastest way to access data. The term normally refers only to the group of registers that are directly encoded as part of an instruction, as defined by the instruction set.
What is the function of CU and ALU?
ALU stands for Arithmetic and Logical Unit which performs Arithmetic functions like Addition, subtraction, division, etc. CU stands for control unit which performs the task of controlling functions of the computer. It monitors and gives proper instructions to all parts of the computer.
What are the functions of CU ALU and MU?
ALU(Arithmetic and logical unit): It takes the logical decision like true/false as computers only works on 0 and 1, which means false or true. CU(Control unit): It supervises all the works going on in a computer. Main decision maker is CU only. MU(Memory Unit): It is clear from its name that it stores.
What is the function of memory buffer register?
A memory buffer register (MBR) or memory data register (MDR) is the register in a computer’s CPU that stores the data being transferred to and from the immediate access storage. It contains a copy of the value in the memory location specified by the memory address register.
What is the function of stack pointer?
The stack pointer — also referred to as the extended stack pointer (ESP) — ensures that the program always adds data to the right location in the stack. The stack stores data from the top down, following a last in, first out (LIFO) data structure.
Is the ALU A register?
One operand for the ALU is always contained in a register. The other operand may be in a register or may be part of the machine instruction itself. The result of the operation is put into a general purpose register.
What is shift register function?
What is Pipo shift register?
Parallel In Parallel Out (PIPO) shift registers are the type of storage devices in which both data loading as well as data retrieval processes occur in parallel mode.
What is T type flip-flop?
The T flip-flop is also called toggle flip-flop. It is a change of the JK flip-flop. The T flip flop is received by relating both inputs of a JK flip-flop. The T flip-flop is received by relating the inputs ‘J’ and ‘K’. When T = 0, both AND gates are disabled.
