An Instruction Buffer Register is also known as IBR. It registers a computer's processor or its Central Processing Unit (CPU).

What is instruction buffer register?

An instruction buffer register is a component of a computer's central processing unit (CPU) that temporarily stores instructions fetched from memory before they are decoded and executed. It acts as a staging area for instructions, allowing the CPU to quickly access and process them in the correct order. The instruction buffer register helps improve overall system performance by reducing the time it takes for the CPU to retrieve and execute instructions.


What Buffer register saves the instruction?

It is employed to hold temporarily the right hand instruction from a word in memory.. For example, The IAS machine's basic unit of information was a 40-bit, so that two instructions could be stored in each 40-bit memory location. Each instruction consisted of an 8-bit {operation code} and a 12-bit address. Hence the IBR (Instruction Buffer Register) is used to temporarily hold Right hand instruction for the next use.


How does the Fetch Decode Execute work?

The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.


How does fetch decode cycle work?

The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

What are buffer registers?

A buffer register is the simplest kind of register; all it does is store a digital information temporarily. It holds the contents of the memory which are to be transferred from memory to other components. By acting as a buffer, it allows the central processor and memory units to operate independently without being affected by minor differences in operation. See the related link for more information.


What is 6 stage instruction pipelining?

1. FI (fetch instruction) - get the next instruction 2. DI (decode instruction) - decode the opcode and operands 3. CO (calculate operands) - calculate EA of the operands 4. FO (fetch operands) - fetch operands from memory (not necessary for register data) 5. EI (execute instruction) - execute instruction storing result if necessary 6. WO (write operand) - write the result in MEM
