Processor Processor is the brain of your computer.Some key conceptsClock : In a computer, clock speed refers to the number of pulses per second that sets the tempo for the processor.CacheA small but fast memory area.Levels of cache exists.Bus (FSB and BSB) : Collection of wires connecting different devices.Pipeline : Implementation technique where multiple instructions are overlapped.32/64 bit processorsThe amount of data a processor can process in a clock cycle. Clock speed and overclockingBUS SPEED x MULTIPLIER = CPU SPEED (Clock) Which processor is faster?100MHz x 10.0 = 1000 MHz133MHz x 7.5 = 997.5 MHz
Some commercially available processors Pentium I-IVCeleronAthlonDuronCyrix C3Itanium (64 bit)Opteron (64 bit)
Choosing the right Processor How do you pick a processor for your system? Performance & Cost How to measure performance?Clock speed is one measure of computer “power”, but it is not always direct…
