Cards in this deck (8)
- 1What is the purpose of the CPU?To fetch, decode and execute instructions.
- 2What is clock speed?Clock speed (Hz) is how many fetch, decode and execute cycles the processor can perform per second.
- 3What is a cache?A small high-speed memory that is used to store frequently used instructions from the CPU.
- 4What is the ALU?The arithmetic logic unit carries out the calculations and logical decisions in the CPU to help decode the instructions.
- 5What do multiple cores within the CPU do?Each core can perform a fetch, decode and execute cycle at the same time at another, which will speed up the CPU.
- 6How can the RAM help the fetch, decode and execute cycle?The RAM can be used to fetch instructions by the CPU but it is slower than the Caches.
- 7What does the Control Unit do?The Control Unit is responsible for decoding the instructions within the CPU. It sends signals to control the flow of data within the system.
- 8What are the names of the four registers?The Accumulator (ACC), the Memory Address Register (MAR), the Memory Data Register (MDR) and the Program Counter (PC).
