(4) Fault tolerance
Not fault tolerant
The system is single fault tolerant
The system is single fault tolerant
(5) Reliability
As the system is not reliable therefore, the online repairability is not possible
As the system is fault tolerant therefore, it is reliable and hence, online repairability is possible.

The system (the NiP, using HXN and PNN as IoC) has shown 100% efficiency for the single and double pair of communication among the NoC. For quad pair of communication, the system has 75% efficiency for HXN, whereas the same system has 62.5% efficiency for PNN
