1.1 Processors Flashcards
What are the three factors affecting CPU performance ?
Clock speed, Cache memory, Number of cores.
What is Clock Speed ?
The number of FDE cycles the CPU completes per second.
What is Cache Memory ( 2 points)
The amount of storage within the CPU.
It stores frequently used instructions.
What are cores/Number of cores ? ( 2 points)
Linked processors within the CPU.
And the number of Arithmetic and Control units the processor contains.
How does Clock Speed work ? ( 3 points)
The CPU broadcasts a signal of 1, then 0, in a loop.
All other devices use this signal to time their actions.
A faster clock means more actions, but more heat.
How does Cache Memory work? ( 3 points)
Data is transferred faster from cache than other sources.
Therefore the CPU can process instructions quicker.
More Cache means more instructions.
How does multiprocessing work ? ( 3 points)
Each core can complete a different task at the same time.
Several problems can be completed simultaneously.
Therefore most programs can run faster.
