Advantages of Parallel Hz

Hi: Below is an example of "parallel Hz" http://img56.imageshack.us/img56/242...example8is.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. With a billion CPUs, the leakage current would kill you. If you want real processing speed at low power, you should look at using 3 phase clocks. There are several advantages to this. You only have to swap two lines of the 3 phase clock to invert the order. This means that the processor can back step. It doesn't really make a general purpose computer but it would be very handy if you were playing jeopardy. |

In addition, pipelining uses buffers and has significant latency. Not something I am found of. My dream PC does not have any buffers or latency. My dream PC uses RAM chips -- instead of magnetic discs -- in to store information. It is entirely chip-based. This PC is built in such a way that it freshly generates the correct electric signals ["on the fly"] instead of playing them back from its ROM chips. There are sets of instructions stored in ROMs. In the case of most PC, these instructions load before the CPU "knows" it has a hard drive or other peripheral devices. However, in my dream PC, those instructions be generated in real-time instead of storing them. I am aware that EEPROM is reliable, low power, customizable, reprogram- able, cheap and proven. But just out of personal preference, my dream PC is hard-wired in such a way that it does not need any ROM. Other specs are below. The stuff below also do not need any ROM memory because they are physically-built to generate the signals which correspond to the following. OS: Windows 98SE Browser: Mozilla Suite 1.8b No fans, no discs, no moving parts, no ROM [except for the CD/DVD recording/playing and re-writing]. IOW, my dream PC would work perfectly but would not need any moving parts, discs, or fans. The "HDD" would consist of silicon RAM chips in place of disc-platters and electric parts in place of magnetic parts. No moving parts, no noise, no fans, no magnets, no hazardous heat. You can buy and/or build a PC like that right now. Solid state IDE hard drives are available, and there are plenty of low power industrial embedded PC's around that don't need fans and can run on couple of watts. You could run 98SE on almost any low power embedded hardware platform. If you don't want the IDE drive you could even use DiskOnChip. Dave. |

I really like my old SB16 card because of its FM synth. |

I hear that if you have nine women working in parallel, you can get a baby in one month, too. You are confusing *clock-rate* and *processor speed*. Although related, they are two different things. |

I really like my old SB16 card because of its FM synth. If it has an ISA bus slot, then yes. PC-104 format is popular with low power embedded PC's, but ISA and other connector and form factors are available. You can get PC-104 format SB compatible sound cards. You can plug a solid state IDE hard drive into ANY PC. If that PC is low enough power not to need a fan, then you have your "dream" machine with no moving parts or noise. Dave. |

Noboby gives a darn about clock rate. It is work done per Watt-second that is the real issue. The 3 phase clock is the lowest number that has an unambiguous order and thus is the lowest power one with the property of a reversible order. With a single clock or a two phase one, the forwards order is always assumed. This greatly limits what the processor is able to do. Consider a simple case like this: You have a list of values that you need to fit a curve to. You know that a program like this: for I=1 to 10 print F(I) next I would print: 1 17 33 105 117 119 67 52 37 23 Given this you can burn a lot of CPU time figuring out exactly what F(I) is. With a 3 phase clock, you only need the list, the program to call the F(I) and a copy of the compiler. You simply invert the C and B clock lines and then look at source code for F(I) to find out what the function is. A great deal of energy is saved by doing this. |

Hi: Below is an example of "parallel Hz" http://img56.imageshack.us/img56/242...example8is.gif erm, didn't you go through this last year too? The benefit of using a billion 1 Hz clock signals to make a clock rate of 1Ghz is that such a system would not get as hot as system running one 1 GHz clock signal . While the overall amount of heat generated by both systems maybe around the same, the system running a billion 1 Hz clock signals will have less heat per area than the system running one 1 billion Hz clock signal. Hence, the former system is far less vulnerable to thermal damage than the latter. Erm, wouldn't this simply be achievable by making a physically bigger 1Ghz chip? A single fast chip is also much more likely to perform better for the same amount of heat since most general computing problems are not readily parallelized, at least as far as I understand it. Let's say two CPUs of different frequencies have been running at the same voltages and amperages and for the same amount of time. The CPU with a higher-frequency will be hotter than the CPU with a lower- frequency. erm, DUH. Quite obviously something like a P4 running at 3Ghz will be hotter than a P4 running at 2Ghz if both used the same voltage. The P4 3Ghz will also do more work than the P4 2Ghz, so what's your point here? This design would go great for any application that cannot be efficiently parallelized [in terms of bits]. Examples of such are arithmetics and Boolean logic. How so? Perhas you can illustrate with an example of 1 single 40x speed chip versus a 10 1x speed "parallel hz" chip? As far as I can see it, if my next instruction was waiting for the result of the preceding boolean logic result, my single 40x chip will get me to the next result 10x faster than your 4x //Hz chip. Since you mention the application cannot be efficiently parallelized, I take it to mean the instructions are highly dependable on each other's results. Thus the faster each instruction gets finished, the faster the next can go. Not much point having 3,999,999 //Hz units waiting 1sec for the result of one instruction compared to a 4Ghz chip that could spit out the next 1million instructions within the same time. But of course I hardly qualify as a chip architect so feel free to point out where I'm mistaken :P -- A Lost Angel, fallen from heaven Lost in dreams, Lost in aspirations, Lost to the world, Lost to myself |

OS: Windows 98SE Browser: Mozilla Suite 1.8b In other words, your system is not upgradable and has to live with whatever bugs there are for the entire "useful" life of the system since everything's hardwired? To put it simply, what I am describing is a PC that does not need to store any information because all of the signal codings for the info is generated in real-time. A PC that does not store any information... what good is it for? Most importantly, though, my dream PC uses parallel-Hz and is massively-serial!!
