Class of Triple Error Control Array Code Applied in Control System
Liu Yun-qing · Journal of Chinese Computer Systems · 2010
With the rapid development of modern industrialization,control system becomes more and more complex,and the possibility of occurring fault is steadily increasing.In order to solve the problem that the security of control system gradually downwards with the expansion of the scale,and therefore encoding method as a kind of software redundancy technique has been applied in control system.For the reason that control system has the requirement of real-time,so Array code has become the mainstream.Although Array code has comparatively short correcting time,the fault-tolerant capacity is limited,it can only correct one or two disk errors.This paper which aiming at the deficiency above puts forward a new kind of encoding method-Extension X Code,this method can recover datas in the case that three disks are in error,Also,encoding and decoding algorithms are presented and it can be applied in the control system used by rocket.
