thank you Colin...it would be nice to have the researchers who did that work confirm power savings

Don't have any numbers for silicon retinas, but the long-term goal IBM's cognitive computers is to simulate corelets on a supercomputer that consumes mega-Watts, then execute them on a cognitive computer that consumes kilo-Watts--1000-to-1 less power.

I think everyone understand it will be much lower power, otherwise you would not bother doing it...but the key questions is how much lower? 10x? 100x? 1000x?

Agree...this is just a small test chip demonstrating technological capabilities...long way to human retina

Regarding power dissipation it should be drastically less, because artificial neurons dissipate very little power except when firing voltage spikes, which typically only occurs every few hundred milliseconds.

Regarding using smart silicon retinas in humans, that would probably be a decade or more away, but in the shorter term the fact that cognitive functions can be built-in should make human-like perception possible for robots.

Pretty cool...it would be interesting to see power dissipation comparison between this approacha nad standard digital computation

Its amazing to see how much science and technology has progressed. Will this be of use to human vision, I mean peeople with damaged retina.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
