Transistor Density On MicroChips & Associated Problems

Transistor Density on Micro Chips is rapidly growing and it could pose a new problem in repairing of these chips. Few companies and universities in Europe have come up with a solution that allows creation of self-repairing chips. #-Link-Snipped-#.

Quoting from above source -


"Because of the rapidly growing transistor density on chips, it has become a real challenge to ensure high system dependability," said Hans Kerkhoff of The Netherlands' University of Twente, and part of the CRISP (Cutting-edge Reconfigurable ICs for Stream Processing) consortium. "The solution is not to make non-degradable chips, it's to make architectures that can degrade while they keep functioning, which we call graceful degradation."

In order to make that graceful degradation possible, the CRISP chip incorporates multiple cores. Different tasks are assigned to different cores, by a built-in resource manager. The connections of those cores are continuously tested, and when a fault is detected, the task assigned to that core is simply reallocated to another one.

Wondering what type of problems are associated with this. Can anyone shed some light on it?
