What "Parallel Hz" Really Is

Hi:

Below is an example of "parallel hz"

http://img56.imageshack.us/my.php?image=clocksignalexample8is.gif

If each clock signal is 1 hz, and you have a billion of them, staggered
such that every 1ns part of the CPU can start, and finish, an
instruction - making the effective 'clock rate' 1 Ghz.

There is no real benefit to using a billion 1 hz clocks to make a clock
rate of 1Ghz and setting up such a system would be a large mess to CPU
designers. However, I find it fun to think about.

The image can be safely seen here, and is hardly worth the effort:

Using the OPs link above crashed my browser. Naughty boy.
Shields up.

Fun or just silly?

It's about as much fun as having 500 cans of beer with only
half a sip in each.

"stupid silly"

you could actually accomplish something with 500 half-sips of beer ;-)

It's silly in the quantities he mentioned but the technique is already in
use, on a more practical scale.

What equipment is it used in?

I used that clocking scheme in an FPGA design years ago. I'm sure
others have also.

There was a /. or Register note about 'Square Clocking' a few days ago:

Effectively running each quadrant of a chip 90 degrees out of phase from
the next, allowing electric power to rotate around the chip.

This would supposedly allow up 75% reduction in the total power budget,
which only makes sense if the process is nearly lossless.

I once built a "TV Typewriter" that used pipelining in the video data
path. :)

Not all problems can be paralelized. Most of the linear logic
type of problems are fundamentaly not paralelizeable.

The CPU you are talking about does exist. It is human brain.
Frequency 10 Hz, number of parallel units 10^10.

It works great for paralelizeable problems such as data-base
search and 3d navigation.
But it sucks at serial only problemes such as arithmetics and
boolean logic.

Isn't this like taking double/quadruple pumped bus and pipelining to
the extreme?

In a "parallel Hz" device the bits maybe completely in serial and the
algorithms and tasks maybe totally non-parallelizable. However, the
frequency is still parallel.

The device I am proposing is completely serial except for the clock
rate.

No. Not at all. As I said in another post, my proposed device is
completely serial except for the frequency. It uses "parallel hz" but
in terms of everything other than frequency, it is totally serial and
non-parallel. Only the clock rate is parallel.

Brain brain!! What is brain??
