Reliability of malfunction tolerance

Resilient computer system design

“…Fault tolerance of RAM structures can be implemented using already proposed generalised algorithm of fault tolerance (GAFT) (Schagaev 1990) further extended in (Schagaev 2008), .…”

Redundancy + Reconfigurability = Recoverability

“…Flynn's [1] classification was used to reference these architectures. The need for reconfigurable architectures in future to produce possible performance gains has been clearly explained: in [2] and [3] with a view to performance and [4] and [5] introducing options for increased reliability. The Passive zone is known: in the form of static and dynamic memories, flash memory, etc.…”

“…GAFT was introduced in [5] and has been applied to various memory structures (Passive zone) [6][7][8] and processors (Active zone) [4,5,10]. Note also that recoverability is practical, if it is invisible for the applications of a CC system.…”

“…The recovery phase of a GAFT implementation might use various redundancy types, as per [4,5,7,8]. Imagine we are capable of implementing GAFT over a CC system.…”

“…The problem is that all these algorithmic implementations are not, in fact, simple sequences. They are most likely to follow a pattern, as presented in [5] and illustrated by Figure 8, where the various steps of the algorithms are dependent on and have feedback loops with other steps.…”
