Frage 3
Frage
The three main parts of the CPU include: [blank_start]the control unit[blank_end] (CU), [blank_start]the arithmetic and logic unit[blank_end] (ALU) and the [blank_start]cache[blank_end].
Frage 4
Frage
The control unit controls what the user can and cannot access
Frage 5
Frage
The cache is very fast memory in the CPU. Recently used applications are stored here so they are quick to access.
Frage 6
Frage
The ALU does all of the calculations. The accumulator is stored here
Frage 7
Frage
The [blank_start]program counter[blank_end] (PC) holds the [blank_start]memory address[blank_end] of the instruction for each cycle. The accumulator ([blank_start]ACC[blank_end]) stores results of the [blank_start]calculations[blank_end] in the ALU. The Memory Address Register (MAR) stores the any memory address for [blank_start]the next instruction[blank_end] to be carried out by the CPU. The Memory Data Register (MDR) stores data or instructions that have been [blank_start]fetched or waiting to be written[blank_end] to memory.

Frage 8
Frage
The fetch in the FDE cycle does:
Antworten
-
Copy memory addresses from PC to MAR
-
Increments the program counter to the address of the next instruction
