The main registers of the CPU are:
Program Counter, Current instruction Register, Accumulator, Memory Address Register, Memory Data Register
Program Current, Current instruction Register, Accumulator, Memory Adding Register, Memory Data Register
Program Counter, Current instruction Register, Accumulator, Memory Adding Register, Memory Instruction Register
Program Compiler, Current instruction Register, Accessing, Memory Address Register, Memory Instruction Register
Which register is described: The register holds the address of the next instruction to be executed. This ensures that the program runs in order and the correct thing is fetched for the next cycle.
Program Counter (PC)
Memory Address Register (MAR)
Memory Data Register (MDR)
Current Instruction Register (CIR)
Accumulator (ACC)
Which register is described: The register is a important register which holds the results of any processing – it is essentially the working memory of the CPU, so anything which has been calculated by the ALU will be sent to this register.
Program Counter (PC)
Memory Address Register (MAR)
Memory Data Register (MDR)
Current Instruction Register (CIR)
Accumulator (ACC)
Which register is described: The register holds the current instruction during processing. The next stage of the F-D-E cycle – the MDR is copied to this register. At this point, the PC is incremented.
Program Counter (PC)
Memory Address Register (MAR)
Memory Data Register (MDR)
Current Instruction Register (CIR)
Accumulator (ACC)
Which register is described: The register holds the memory location of data/instructions which must be fetched. This is instrumental to the fetch-decode-execute cycle – each cycle, the PC is copied into this register to get the next instruction.
Program Counter (PC)
Memory Address Register (MAR)
Memory Data Register (MDR)
Current Instruction Register (CIR)
Accumulator (ACC)
Which register is described: The register stores data/instructions which are coming from or going to the memory. Again, this is needed to run the F-D-E cycle. The next instruction will be fetched to this register from RAM, so that it can be decoded.
Program Counter (PC)
Memory Address Register (MAR)
Memory Data Register (MDR)
Current Instruction Register (CIR)
Accumulator (ACC)
Which step of the Fetch-Execute Cycle happens first?
The PC is copied to the MAR
The contents of the memory location in the MAR are fetched to the MDR
The MDR is copied to the CIR
The PC is incremented by 1
The instruction is decoded and executed.
At the start of the F-D-E Cycle the PC copies its value to the (a)
In the F-D-E cycle the pc increases by?
(a)
In the F-D-E Cycle when the instruction is fetched from memory by the MDR the instruction is copied to the?
(a)
