bio-inspired architectures are very relevant today
The CMOS industry is facing a number of hurdles to continue improving processors in terms of size,
performance and dissipation. While the number of transistors keeps increasing, since 2005, their frequency is stalling due to the
extremely large thermal dissipation. In order to keep on increasing performances, computer architects have introduced parallelism
in their systems via multi/many-core architectures. Nevertheless other technical complications will have to be solved such as
and the increasing number of defective components due to their shrinking dimensions.
In this context, bio-inspired computing architectures are seen by
as a pertinent solution to complement classical processors
Indeed, bio-inspired architectures are massively parallel, large scale, and highly interconnected. This confers them extremely
interesting qualities such as speed, low energy consumption and high tolerance to component defects and variability. The best example
is our our brain, which can interpret complex scenes in fractions of seconds, demands only a few meals a day (less than 10 MJ, to be compared to
105 MJ for a supercomputer) and manages to compute despite the fact that we lose about 104 neurons a day.
