It's one thing to store a small amount of data (a few thousand bits) very densly. It's another to be able to write and access large amounts data stored at that density reliably at high data rates. Just achieving a high density of data storage is not a big deal. The article doesn't indicate that they've actually solved the problems necessary for a successful commercial product.
They get a little better every time. This summer's race will be considerably longer than the usual race. 2500 miles is nothing to snuff at for these vehicles.
Two big factors in determining the leaders in the race are the reliability of the vehicle, and the driving strategy. That reliability is a factor is pretty obvious, you break down, you loose time. In a race of this length teams should design their cars so that things like changing a tire are not major headaches. Strategy is important because the sun doesn't shine all the time, and in all places. Teams need to get all the weather information they can and do a good job of planning. If they know some part of the day's route will be cloudy, they need to plan accordingly.
These aren't the slow cars of years ago, these things can move right along with a good charge and bright sunlight. They still look very uncomfortable to drive, though. No Air conditioning, and the suspensions are not usually very soft.
Competitive? It's Intel that's not competitive. For the highest performance x86 chips, including dual cores, AMD's leadership will not be threatened by intel for at least another year. AMD is in the driver's seat and can charge the high prices because of it. It's something that until recently they've really never had the luxury of doing before.
See Sharp's LH7A404. This puppy includes
* an 800x600 LCD controller
* A Codec for a modem
* A 100 Mbs Ethernet controller
* USB ports ( both sides )
* Touch screen controller.
* PS/2 Mouse and keyboard port
* Serial ports
I believe that's everything you asked for, but all on a single chip. Plus its ARM based, so I'm sure that's Knoppix is easily portable.
If you've been paying attn to the stock market, last quarter AMD did not make nearly as much as they were expecting on flash sales because Intel was dumping flash memory in order to depress prices of flash. Thoughts are that this was done specifically to hurt AMD's bottom line.
It's like the memory/speed tradeoff that programmers have to deal with
Memory - speed trade off? Hockey pucks. Because cache memory is so much faster than going to ram, programs these days are optimized for speed BY optimizing for size!
I'm not sure you'll be able to get down to 1 watt on a good desktop type cpu, but I'ld bet that you could get down to two or three watts.
From what I understand, the leakage current of the 90 nm chips is noticably higer than that of 130 nm chips, so first you'ld probably start by designing your chip to use 130 nm technology. (Maybe you could used something a bit smaller, depends on how much leakage curren you want to tolerate).
Secondly you'ld want to use an instruction set that's more power efficient to decode than that of x86 architecture, meaning it will probably be an ARM based architecture as it is quite efficient this way.
Thirdly you'ld probably get elimanate things like superscaler architecture and much branch prediction logic. Branch predicition logic takes quite a bit of room and would likely use a fair amount of power, however you're going to loose some performance.
Generally you'ld just keep subtracting things off until you got the power down to where you want it.
Take a looksie at Sharp's ARM based chips. These may be close to what you're looking for.
They're under 1 watt, but are not quite a general purpose CPU.
These appear to be MIPS based chips. Sharp has some
ARM based chips that are geard for similar applications and provide similar functionality. These also, IIRC, run with fairly low power and have 32 bit cores. The high power requirements of x86 architectures is due to their very high clock speeds and all the complexities of a general purpose CPU chip (mmu, floating point, cache, fancy branch prediciton logic, etc).
If MS refuses to service me, then they can refund my money.
The way I see it, is that MS is servicing you, the same way that a bull 'services' a cow. (Yes, this is the euphamism commonly used in the livestock industry.)
he weather has not changed significantly in 30+ years (lifespan or more for many of us),
I beg to differ. It has gotten significantly warmer in the area where I live. Very noticably warmer. I'ld say on average 5-10 F warmer. The growing season for crops has been extended by about two weeks.
P.S. I live near Podunk, Iowa.
Since working memory is known to predict many higher-level brain functions, the research calls into question the ability of high-pressure tests such as the SAT, GRE, LSAT, and MCAT to accurately gauge who will succeed in future academic endeavors.
I never thought that these tests were particularly high pressure. I took my ACT's (SAT equivalent in midwest) having only about four hours of sleep the night before (prom night). I did reasonably well.
there probably would be no kinetic interaction between the two if they were to "collide".
I would bet that there would be a number of stars in the galaxies that would have their motions markedly changed. You'ld probably have a number of stars being scattered around and exiting the galaxies at high velocities relative to other stars . There may even be an actual collision or two.
Well said. Back in college, emphasis was put on designing power supplies in my EE course (for non EE majors). It gives you some respect for what those designing these things have to deal with.
Meanwhile, like you say, the tests performed were very incomplete. You really need to know how they handle transient loads, and the ammount of ripple in the voltage when the supply is reasonably heavily loaded.
Also there are things like overvoltage and overcurrent protection. These will shut the power supply down in order to avoid damaging components.
I believe one or two of the PS in the tests did do this.
The overcurrent protection is one reason it is good to have a properly sized power supply, one that is neither too large nor too small. If you use a power supply that's overbuilt, it will happily toast your components by supplying them with amperage that obviously is indicative of a component failure. By not shutting down, the malfunctioning component can generate large amounts of heat that stress and destroy other components. You end up with a machine with loads of problems, not just one.
Yep, a good power supply is a lot more than a transfomer, diodes, and a few capacitors. Myself, I think I've only ever had one problem with a computer power supply. They've been pretty good to me.
In some apps, it turns out, that multithreading doesn't help much might be expected. When one really analyzes what's happening, one often finds that one thread locks a resource that's needed by the other threads, so effectively only one thread ends up running at a time because of record/resource locking. In fact a well written, non threaded code can frequently execute faster because they don't spend half their time making calls for acquiring and releasing locks on resources.
But I'm sure you're correct in that software designers will start paying more attention to how they can make their software run more efficiently on multi-core processors.
How many developers out there have yet to realize that size optimization is speed optimization? Reduce your data and code size and the processor can spend more of its time executing from cache, and less time fetching from that relatively slow main memory. Also avoid deeply nesting subroutines within major loops.
That's about where mine's at too. Actually at the stock speed, idleing, its about 40 C. Overclocked to 3000+ (2200Mhz) it idles at about 44 C. It will rise several degrees after it's been busy for awhile.
I haven't read much recently from AMD about what's happening with their schedule is for releasing their dual-core chips. I think the dual core Opteron was supposed to get released about the same time as Intel's dual core chip, and that the dual core amd64 was to be released about a half year later. I wonder if AMD is waiting for Intel's release before releasing their chip. That certainly would take the wind out of Intel's sails. I had heard that they had produced working dual core chips several months ago.
While Intel is certainly not down and out, I think they'll be finding it tough going this year until they manage to re-take the lead on top end x64 chips. AMD will be able to charge nice prices for its top of the line chips for awhile yet.
What do people here know about purchasing plans for IT managers for the coming year? Are they looking to get into 64 bit computing, or are they planning on waiting awhile yet until Intel gets their chips in order?
This chip would be a good fit fore one of those newfangled two slice toasters. I think we may have to wait somewhat longer for for a chip to power those four slice toasters, especially if it's to interact with the operator like the one on Red Dwarf.
I think you'll be able to screw them into a standard light bulb socket. I don't know how much light they'll give off though. Maybe quite a bit for a brief instant as you flip the switch on.
