Objectives :
Develop low cost but highly reliable system (Note that reliable system costs more)
Expand the use of FTS in everyday ES
Contribute for the safer society
Method
Rasberry Pie (RP) board as baseline board
Integrate two RP with heartbeat mechanism
Find worst case failover time to identify the use of RP-DMR
Perform FHA, FMEA, & FTA to assure the safety of RP-DMR
