Factors Affecting Procesor Speed

Question 1

Number of cores?

Answer 1

Each core performs its own fetch execute cycle, sp different applications can be allocated to different cores.

Question 2

Cache memory?

Answer 2

Small portion of fast memory.
Cache stores frequently used info and reduces time wasted, the more cache a processor has the more information it can store and the less time it wastes fetching the same information.

Question 3

Clock speed?

Answer 3

Frequency of the pulses. The higher the frequency the more cycles can be completed in a period of time.

Question 4

Word length?

Answer 4

Higher word lengths allows for more bits to be transferred and manipulated as a single unit.

Question 5

Address bus width?

Answer 5

Number of parallel words that make up the bus. Increasing width of the address bus increases the range of addresses that it can specify.

Question 6

Data bus width?

Answer 6

Increases the volume of data that can be transferred over the bus at any one time . Wider bus= more data reducing the number of cycles required to fetch a lot of data
