Register to register addressing mode is faster because you don't have to do an extra memory access cycle or more.
Register to register addressing mode is faster because:
- Registers are part of and are directly accessibility by the CPU assembly.
- They electronics that make up a register use more expensive but faster circuitry.
- Since it does not require memory access, the steps and time involved in memory address decoding and memory access are skipped.

Which register modifies ret instruction?
instruction register
What register points to the next instruction?
actually register holds the data..there are 6 register which are temporary registers..program counter holds the address of next instruction to be fetched..instruction register holds the currently executed data...
What is the consists in the Instruction register?
The Instruction Register contains the current instruction being executed. It is an internal, special register, and you can not do anything explicit with it. If you are referring to the Program Counter, that simply contains the address of the next instruction to execute. It is incremented for each opcode and operand byte fetched.
What is CLK in Instruction register?
Clock
What is register addressing mode?
If 8 or 16 bit data is required for executing the instruction present in register/register pair and named of register/register pair is given along the register.this instruction is called register addressing mode instruction.for example:MOV B,A
What is the name of the cycle in which an instruction is taken from memory and loaded into the instruction register?
Fetch
Instruction Buffer Register?
An Instruction Buffer Register is also known as IBR. It registers a computer's processor or its Central Processing Unit (CPU).
Can arithmetic be performed in the instruction register?
yes
What is the function of the PC register in the 8086 CPU?
There is no PC register in the 8086/8088. It is called the IP register by Intel and it stands for the Instruction Pointer. It contains the address of the current/next instruction to be executed.
What is the function of instruction register?
The Instruction Register (IR) stores the instruction currently being executed. In simple processors each instruction to be executed is loaded into the instruction register which holds it while it is decoded, prepared and ultimately executed.
Which register can be changed directly using pop instruction in 8086?
stack segment register
Draw and explain the bloack Daigram of Von Neumann machine?
Block diagram of the von Neumann architecture: MQ, multiplier quotient register; IR, instruction register; IBR, instruction buffer register; MAR, memory address register; MDR, memory data register
