Hardware Faults

Chapter explains hardware faultsHardware faults, their origins, dependency on technology used and some known solutions of fault toleration using error correction codes and redundancyRedundancy hardware schemes. Shown that with growing density of hardware there is a risk of multiple temporary fault faults grows at order of magnitude prime concern for designers of new computer systems for safety critical application. Hardware faultsHardware faults occur due to natural phenomena such as ionized radiation, variations in the manufacturing process, vibrations, etc. We present in this chapter a short introduction to hardware faultsHardware faults, show the typical fault types and patterns and also give examples how to deal with these faults.
