Select the correct registers of a CPU:

• PC(Program Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)

This register stores the current instruction being decoded and executed

• PC(Programming Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)

This register is used when carrying out ALU calculations; it stores data temporarily during the calculations:

• PC(Program Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)

This register stores the address of the memory location currently being read from or written to:

• PC(Program Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)

This register stores data which has just been read from memory or data which is about to be written to memory:

• PC(Program Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)

This register stores the address where the next instruction to be read can be found:

• PC(Program Counter)

• ACC(Accumulator)

• MAR(Memory Address Register)

• MDR(Memory Data Register)

• CIR(Current Instruction register)
