Is it possible to use a billion 1Hz clocks to make a clock rate of 1 GHz?
How would this be done?
Thanks

half_pint said: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?
George said: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.
half_pint said: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.
half_pint said: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.
Curious said:Huh? I can make one if I already have one?

rate of 1hz then wouldn't placing a billion 1 Hz clocks in parallel
[each sample getting its own sampling] to gain a 1 GHz rate be safer
than 1 clock running at 1 GHz? The advantage I see is less heat
generated by the CPU. A CPU with one 1 GHz clock clock will certainly
get hotter than a CPU with a billion 1 Hz clocks. Higher-frequency
generates more heat given the same voltage. A billion 1 GHz clocks
each doing the work in parallel generates much less heat with same
effiency as one 1 GHz clock doing all the work in serial.

is one of the reasons that SATA can go faster than PATA.

Parallel *bit stream* is possible. Is parallel *clocking* possible?
