Overclocking with more clocks

Is it possible to use a billion 1Hz clocks to make a clock rate of 1 GHz?

How would this be done?


Thanks

Most 1Hz "clocks" use a higher frequency standard, and divide down from
there. If the frequency standard was 1MHz for example, one could
multiply it 1000 times to get 1GHz at the same standard frequency base
as the 1Hz "clock". There are many kinds of multiply and divide circuits.

No.

Not really possible, you could make lower frequencies eg 1/2, 1/4, 1/8 Hz
but not higher ones (well you might manage 2 and 4 Hz possibly)

Nerves can fire up to 1 KHz max. At pitches above 1 KHz our cochlea
makes-up for this by firing different lines of neurons at succesive
cycles.

"Volley Principle: The volley principle reconciles the fact that the
cochlear microphonic mimics the sound pressure waves with the
implausibility of the temporal code. Wever suggested that while one
neuron alone could not carry the temporal code for a 20,000 Hz tone,
20 neurons, with staggered firing rates, could. Each neuron would
respond on average to every 20th cycle of the pure tone, and the
pooled neural responses would jointly contain the information that a
20,000 hz tone was being presented."

"Phase Locking is an empirical observation that supports the volley
principle. When 8th nerve neurons fire action potentials, they tend
to respond at times corresponding to a peak in the sound pressure
waveform, i.e., when the basilar membrane moves up. The result of this
is that there are a bunch of neurons firing near the peak of each and
every cycle of a pure tone. No individual neuron can respond to every
cycle of a sound signal, so there must be different neurons firing on
successive cycles. Nonetheless, when they do respond they tend to fire
together."


Is it possible design an overclocking scheme similar to that of the
cochlea?

I think the trouble is you need a 1 ghz clock to syncronise the waves.
So yes, you can make a 1 ghz clock, *if* you already have one.

Yes, it is the offset that is the bear... Plus, I assume you are referring
to the cheap xtal oscillators...they DO need to be run for around 168 hours
(aged) before they become fairly stable.

You'd basically be time division multiplexing them (i.e., each would have
it's own time slot for it's pulse...it isn't practical, but theoretically
possible). You'd also have to shorten the pulses appropriately.

Yes and TMD would required a 1GHz clock, so your using a 1GHz clock
and billion 1Hz clocks to produce a 1GGz clock.
Obviously the billion 1 hz clocks are surplus to requirements.

Huh? I can make one if I already have one?

You ***just*** VBG need the 1GHz clock to initially get the phase offsets
right. After that, you've got the billion 1Hz clocks running asynchronously
and everything will be fine (because we all know how stable crystal
oscillators are). C'mon now, we gotta help this guy clear out the 1 billion
oscillators in his closet!
