I.Ilayaranimangammal, R.Sornalatha

To detect and correct the errors in the Flow diagram of all digital systems using RAPTOR.By analysing the characteristics of PAD and structured flowchart, and a structure identification and coding algorithm are put forward for structured flow diagram and PAD. Finally a integrated development platform is developed using such algorithms, including flowchart modelling, code automatic generation Fault tolerance technique using TMR for exposure and expulsion the soft errors in the digital systems. Faults are detected and eliminated without interrupting the normal functioning of the circuit. Single point of failure, is eliminated and implemented as a fault tolerant using a Triple Modular Redundancy (TMR). Conventional lockstep scheme uses duplication with comparison (DWC), the presence of fault is detected, but it fails to indicate the location of fault which is overcome in enriched lockstep by triple modular redundancy (TMR). TMR technique incorporates both transient and permanent faults. The new intensifying lockstep scheme requires significantly shorter recovery time than conventional lock step. It uses significantly less number of slices.
