Chapter 101: Those who play with hardware are also confused

The X-ray came, and the red hat also came, Xiao Liu immediately turned off the phone, and then handed the tablet to the red hat with some nervousness.

Of course, the red hat here does not mean an agent with a red hat, but a title similar to the red-top director and the red-top businessman, which is probably the name of those technicians who have defected to the official.

Their knowledge of the hardware itself is far beyond that of ordinary computer industry practitioners, some of them may be from the manufacturing industry, and some of them are simply civilian, but no matter what, they can find a few scrap computers from the scrap yard and change the hardware equivalent to the best brand machine of our time. It can be said that if the legendary guys who pricked the lattice with needles and used magnets to collect tapes really existed, it must be this group of red hats.

Seeing the person operating the security equipment next to him put the tablet under the "lens", Xiao Liu couldn't help but get nervous again-

"Well, boss, do we want to put a layer of radiation protection film?"

"Don't make a fuss, I'm still taking an X-ray of that thing!" Lao Zhang glanced at Xiao Liu, and then signaled to start.

The invisible X-ray hits the tablet, and the monitor on the other side shows a strange picture, although at first glance, it looks similar to an ordinary microcontroller, which is composed of various electronic components and a substrate, but that is only for people who do not know how to do it, and in the eyes of the red hats, it is a completely different feeling.

So, everyone with the relevant knowledge makes a SAN check.

Due to the different knowledge systems, the whole failed and fell into temporary madness.

Crazy genre – gibberish.

"It's not scientific! This arrangement is completely unscientific! ”

"Am I crazy or is the guy who made this tablet crazy?"

"Why is it made into such a long strip, and I am afraid that two-thirds of the crystalline silicon will be lost when cut into such a piece? You can't be so early if you have money! ”

"Does this symmetrical structure make any sense? Why can I connect processors together? How did he solve the compatibility? ”

"This solution, without overheating? Or are you not tested? ”

……

A large series of chaotic and crazy words, but with a rather professional nature, came out of the mouths of different red hats, and it was not until five minutes later that someone finally stopped.

System Data ......

The red hat at the head lowered his head, and suddenly such a sentence came out of his mouth.

"What?"

"I said system data! There are a total of twenty-four processors on this board, although fortunately it is relatively small, but regardless of priority, even if each one is one core, there are twenty-four cores, and there is no enough exquisite core solution to unify these processors! Red Hat pointed to the three-layered octagonal processor on the screen, his face grim, his eyes bloodshot, as if all his life's learning had been overturned in this instant.

"If we can understand it, we won't ask you for help, but the computing power of this tablet is at least dozens of times that of an ordinary octa-core processor, and from the core language to the computer language and the existing computer language are completely two concepts, this thing is completely different from the computer I know except for the basic operating principle and appearance."

"How is it different? Except for a little symmetry, there is no difference, huh? Captain Zhang didn't know where to take an ordinary tablet and put it on X-ray, compared the two tablets and looked at them for a long time, and suddenly found that he didn't see anything.

"Zhangtou, how many black squares do you have on that board first?" The red hat glanced at Lao Zhang and asked as tactfully as possible.

"CPU is CPU, and black square, are you mocking me?" Lao Zhang's face turned dark, even if he didn't understand electronic products, he still knew what the CPU was, "You mean these black bars are all CPUs?" Looks like a little bit more...... Isn't it true that computer performance is better with more CPUs? I remember that there seemed to be tens of thousands of the lights of Shenwei Taihu Lake! ”

"Boss, this can't be counted like this, how big is our family's divine power, how big is this thing? And the problem is not in the quantity, but in this arrangement! You see, there are 12 CPUs in it that are placed diagonally! ”

"That's true, is there anything in that?" Lao Zhang looked at the layout of the twenty-four CPUs, and it did look a little strange, as if it was three regular octagons with rings in each other.

"Generally speaking, the layout of the circuit board itself needs to be specially designed, every resistor and every line on it must be carried out in accordance with the basic rules as much as possible, and at the same time, saving space on the substrate is also necessary, but not to mention anything else, the substrate itself not only causes a large number of redundant lines in pursuit of symmetry, but also has a lot of gaps that should not exist, such as the octagonal interior surrounded by the twenty-four CPUs, which is enough to put down a standard CPU or several resistors. However, it would rather squeeze these things into a pile and make such a large space, which is completely inconsistent with the basic law of substrate design! ”

Red Hat scratched his head a little franticallyβ€”

"If only that's it, but the problem is that the layout of this CPU itself is problematic! Generally speaking, the advantage of multiple CPUs is multi-threaded computing, and the parallel CPUs in groups of three here are laid out like this, that is, it can make these three CPUs calculate different data at the same time, but the problem is that the eight groups of CPUs themselves are connected in series! That is to say, a set of data has to be repeatedly entered into eight sets of CPUs to calculate eight times, so that the actual computing power should only be calculated for those three parallel CPUs, but you tell me that the computing power of this tablet is dozens of times that of ordinary octa-core processors? ”

"Maybe there's something to be meant by this layout?" Lao Zhang didn't understand much after listening to it for a long time, so he could only say it vaguely.

"Connotation? I don't see anything other than a crazy symmetry fetish! Anyway, you're not kidding us, are you? Redhat stared at the tablet as if he wanted to take it apart.

Xiao Liu immediately pulled the tablet out and hugged it back into his arms, looking at the red hat with a vigilant face, very unhappy with the other party's sarcasm-

"Don't talk nonsense about what you don't understand, binary is still deduced from the philosophy of planting flowers! How do you know that symmetrical layout doesn't play a role in the layout of the board line? ”

"Everyone is a materialist, don't confuse philosophical beliefs with science, the so-called binary refers to the yin and yang gossip, it's just a gimmick, you let the Taiji diagram make a calculator and try it!" Red Hats have the typical characteristics of a technician – more realistic.

But his words just woke up Xiao Liu-

"Yin and yang? Tai chi? Gossip? I understand! I know why this is laid out the way it is! ”
