RPAGF Chapter 713 The cheat code is really powerful!
Chapter 713 The cheat code is really powerful!
The outcome of the competition was self-evident.
However, things were different when Jiang Xia came to summarize.
"How many years did it take Sister Zhang to achieve what she has today? Ten years? Twenty years? How many people can match her hard work and talent?"
"And now?"
Jiang Xia patted the young worker next to him who was looking at him with starry eyes: "No need for ten years of hard work, no need for special talent. As long as you can recognize numbers and know what multiplication and equal signs mean, anyone can use them to calculate the accurate result in a few seconds."
"That's its significance. It doesn't require you to be a 'calculator'; it makes the most complex calculations as simple as drinking water and eating. It's not a toy for racing against an abacus; it's a tool that can give the abilities of a 'calculator' to every ordinary person!"
Jiang Xia's summary became the conclusion of yesterday's competition.
This was only because Jiang Xia saw they were all on his side and didn't do anything malicious. If he had really broken down and explained the intricacies of the circuit boards inside the calculator, Yang Erlengzi, upon hearing this detailed explanation, would probably have to recite the dictionary two or three times, and the strict and disciplined Secretary Liu would have prevented him from even leaving Beijing.
why?
Tsk tsk, Jiang Xia's calculator even has a universal interface. If you connect it to "Big Yellow Doppelganger," you don't even know how fast the current transistor computer's processing speed will be improved.
Why do I say that? Because at the most basic level, the processing core (CPU) of a transistor computer can only perform very basic operations.
The main operations are "addition" and "bitwise operations". More complex mathematical operations such as multiplication, division, and square root are ultimately decomposed and transformed into a series of time-consuming addition and shift operations at the software level.
The calculator assembled by Jiangxia actually contains two dedicated digital logic circuits: a hardware multiplier and a hardware divider.
Their design goal is singular: to complete the relevant calculations as quickly as possible. They have specialized internal circuit structures (such as array multipliers, Booth-coded multipliers, etc.) that can directly process the multiplication of two binary numbers and output the product result in one step.
This means they don't need to break down multiplication into many additions and shift operations like a CPU does.
This is equivalent to equipping the computer's CPU with two powerful "external engines"!
When this calculator is connected to "Big Yellow's Doppelganger" via the interface, it is no longer just a standalone calculator. It transforms into a dedicated coprocessor or accelerator card for this mainframe computer!
In this mode, when the Big Yellow clone needs to perform multiplication or division, the CPU simply issues a single instruction through the expansion interface: "Hey, multiplier/divider, calculate these two numbers for me!" The actual calculation is then performed in parallel and at high speed by these dedicated hardware circuits. After the calculation is complete, the result is sent back to the CPU through the interface.
In this way, complex multiplication and division operations that originally required the CPU to execute dozens or hundreds of instructions can now be completed with just a few instructions (sending commands and waiting for results)!
This efficiency improvement is orders of magnitude! It completely frees the CPU from the most demanding mathematical calculations, allowing it to focus on other tasks. Large matrix operations, complex physics simulations, advanced graphics processing, and other tasks that were previously impossible to handle in real time due to CPU speed limitations are now possible.
The overall computing power (throughput) of the entire computer system will be dramatically improved!
Hehehe, does it look familiar? Does it have a bit of a "graphics card" vibe?
Brilliant! That's exactly right. Computers are just about adding functional modules to them!
Therefore, Jiang Xia's statement that "even he himself doesn't know how much the computing speed can be improved" is by no means an exaggeration! This idea of accelerating specific calculations through dedicated hardware is absolutely revolutionary in this era of extremely limited CPU performance!
It's like giving a bulky mainframe computer a pair of wings specifically designed for high-speed mathematical calculations!
If someone in the know were to find out, they would be absolutely amazed!
No wonder Jiang Xia kept it a secret, only showing the calculator's surface functions. This core "plug-in engine" design is the real "killer app"!
Therefore, it's quite reasonable that Jiang Xia, who is usually careless with naming things, gave this calculator such a powerful name as "Red Dragon's Eye".
……
Thinking of all this, Jiang Xia snorted smugly. The original members of the Dongfeng 113 project looked at this designation with surprise.
Yes! Jiang Xia rushed to create this "cheat code" because he wanted them to experience the powerful auxiliary role of a computer with the "cheat code" in numerical calculations on the project.
Hehehe, seniors, just watch quietly as I silently rant!
Jiang Xia tossed the calculator to Yang Erlengzi, letting him play with it. He then ran to the "Iron Mule" to try and contact his senior brother from Yunnan and Guizhou via digital radio to discuss precautions for testing the "cheat".
As is customary in Jiangxia, backups are still in place. Before setting off in the morning, Master Weng had already prepared another calculator, and Jiangxia had instructed Secretary Liu to pack Master Weng and the calculator and send them to the Academy of Sciences early in the morning.
On one hand, they had the senior apprentice from Yunnan and Guizhou calculate just how fast the "cheat code"-equipped Big Yellow clone could perform in scientific computing. On the other hand, Master Weng's micro-carving skills were considered a waste of his talents in the machine factory.
His true calling lies in playing with lithography machines...
Look, our little ahoge has evolved once again. It can even "assign duties according to its abilities" now.
Although his evolution speed is somewhat slow compared to other main characters—he can only painstakingly add modules to his "Big Yellow clone" right now—others would probably have already built a quantum computer by now…
"Senior Brother Yungui! Did you receive the items?"
"Damn it! What's wrong with your brain?! Ah... ah... ah!" Senior Brother Yun Gui delivered a triple blow to the soul over the radio.
"You son of a bitch, why didn't you come in person! Didn't you see? 10 16-bit floating-point operations! 0.863 seconds! 0.863 seconds..."
"Ah...ah ah! You little rascal, come here to your senior brother, your senior brother is going to kiss you to death..."
Well, it seems this cheat is working well; even someone as scholarly as Senior Brother Yungui is swearing now...
Jiang Xia expressed understanding regarding the minor matter of being scolded.
You should know that when using "Big Yellow" to perform 8-digit integer calculations before, it would take more than 10 seconds to get the answer...
The contrast is quite striking.
Just as Jiang Xia was about to say something more, Senior Brother Yungui left with the words, "There are still tests to be conducted. I'll contact you later!" and hung up the radio.
"Tsk, why the rush? I wanted to ask about the lithography machine..."
"If a lithography machine is developed, that 'brick' should be much smaller..."
Little Dumb Hair grumbled as he climbed down from the armored vehicle, about to ask Old Wang when they were going to have to wait.
"Woo..."
A deep and powerful whistle, like the roar of a sleeping dragon, came from afar and tore through the silence!
Immediately afterwards, the earth seemed to begin to tremble slightly! A powerful pressure, carrying a metallic chill, surged from the end of the railway tracks like a tidal wave!
"My God... what... what is that?!" Yang Youning was the first to exclaim, pointing into the distance with his eyes wide open!
After glancing at it, Old Wang turned his head blankly and looked at Jiang Xia, who was standing on tiptoe looking into the distance.
"This little brat is way too pampered, how come they even brought this up?"
