Question

Hat is the minimum set of registers for von-neumann machine ? what are the functions of these registers ?

Answer 1

The functions of is the minimum set of von-neumann registers are as follows:

• Von-neumann machine - also known as von Neumann architecture or Princeton architecture refers to a computer architecture, described by John Van Neumann in 1945. This architecture refers to multiple Registers such as-

• Memory Address Register (MAR): Fro storing memory locations on instructions.

• Memory Data Register (MDR): For storing instructions fetched from memory.

• Current Instruction Register (CIR): For storing most recently fetched instructions.

• Instruction Buffer Register (IBR): For storing the instruction that is not to be executed immediately.

• Program Counter (PC): For keeping track of memory locations.

• Accumulator: For storing results of calculations made by ALU.
