- 2one cycle of a cpufetch, decode, execute and store
- 3how to improve CPU performance- increase the number of cores, allowing more cycles to be performed simultaneously
-increase the clock speed of the CPU, allowing more instructions to be completed per second
- increase the size of the cache, allowing more commonly used data to be stored closer to the cpu. - 4CLU(control unit)
sends out signals to control how data moves around the parts of the CPU. - 5ALU(arithmetic logic unit)
