Fetch Execute Cycle + Others

What is stages 1-2 of the fetch execute cycle?

1=Processors sets up the address bus with the required address.

2= The processor activates the read line on the control bus

stages 3-4 of fetch execute cycle

3= An instructions is fetched from the memory location using the data bus and stored in the instruction register.

4= the instruction register is then interpreted by the decode and carries out

what are the four factors that affect the performance of the computer?

Number of processors(cores), Width of Data bus, Cache memory, Clock speed

The more cores a processor has,

The more sets of instructions the processor can Receive and process at the same time, this improves system performace

a dual processor is not as fast..?

as a single processor running at twice the speed.

What is clock speed?

This is the electronic unit that synchronises related components by generating pulses at a constant rate.

the clock rate is the..?

frequency at which the clock generated pulses

by increasing the data bus from 32 wires to 64 wires, the computer..?

can transfer twice as much information in a single fetch

What is cache?

cache is a small amount of fast accessible memory, usually on the same chip as the processor

the processor checks for this data..?

or instructions before accessing the main memory if it finds the data and instructions then this is termed as cache hit resulting in an improved performance
