Cards in this deck (9)
- 1What is the purpose of a CPU?To Fetch, Decode and Execute instructions
- 2What three factors affect CPU performanceClock speed, multi-core, cache size
- 3What is Clock speed?How many Fetch, Decode, Execute cycles a core can
complete per second - 4What is Cache?A small high speed memory used to store frequently used instructions
from the CPU (multiple levels for overflow) - 5What does it mean to have multi-cores?It is having multiple cores to run instructions at the same time
- 6What is the role of the Control Unit?Responsible for decoding the instructions and It
sends out signals to control
how data moves around the
parts of the CPU - 7What is the role of the ALU?Carries out calculations/logic decisions required to decode the instructions
- 8What does ALU stand for?Arithmetic Logic Unit
- 9What are the four registers?Accumulator ACC, Memory Address Register MAR, Memory Data Register MDR, Program Counter PC
