- Factors affecting processor performance
- Address bus width
- Can address more unique memory locations
- Increases max potential memory usage
- Increasing number of cores
- Multiple processors can carry out tasks in parallel.
- A task can also split up to be run on different cores in parallel to speed up execution.
- Increasing word length
- CPU can process more data
- Processor can have larger amount of memory through direct addressing
- Larger instruction set
- Cache memory
- Instructions or data needed frequently are placed in a temporary area of memory (separate from main memory), allowing it to be quickly used by the CPU, speeding up execution
- Depending on how close those cache memories to the CPU, they can be classified as level 1,2, 3 etc.
- Increasing data bus width = move more data around per unit time
- Increasing clock speed allows processor to execute more instructions per unit time
- Address bus width
