Chapter 351 Heavenly Eye

!

After implementing the common logic circuit, Lin Hong was extremely excited.

This is understandable. After all, this is an important step for him to sell in his brain. At this level, his superbrain system has dawned, which is the hardware he made himself.

While the iron was hot, he immediately began to make the adder.

The addition principle of

binary is actually similar to that of decimal, and it is also the corresponding addition of bits to bits, such as one bit plus one bit, ten digits plus ten digits, which is calculated separately when it involves carry. Binary is also similar, and it is also a corresponding addition. Its basic principle is: 0 plus 0 equals 0

0 plus 1 equals 1,

1 plus 0 equals 1,

1 plus 1 equals 0 to 1.

According to this rule, the results are represented by two parts, one part is " sum" and the other part is "forward". The two parts can be calculated separately, which is much simpler than the addition of the decimal system.

The binary addition of

bit is the simplest. The result can be represented by a bit "and" and a bit "forward". The maximum value is "2" represented by 1 plus and 0 carry".

For larger numerical addition, you just need to use parallel calculation to expand the number of bits.

implements the simplest part, and it is much easier to expand. Basically, it is just a repetitive process, as long as the technology allows to achieve as many bits at will.

Since the current CPU bits have reached 32 bits, Lin Hong also plans to directly design a 32-bit adder.

Because the CPU design has ready-made reference materials, Lin Hong's next process is completely a "physical work", which is not challenging. All he needs is energy and time.

However, because his adder is designed for the real-time operating system, he did not copy the design of INTEL or AMD, but made certain modifications.

He directly divides the 32-bit adder into two, divided into low 16-bit adder and high 16-bit adder, and then takes the carry output of the low 16-bit adder as the selection signal to select the sum of the high 16-bit adder and the carry output of the 27th bit.

The decit output of the 27th bit is used in overflow logic judgment.

Through this processing, a 32-bit adder is simplified to 4 into two 16-bit adders, and finally divided into smaller modules with 4 bits as units. The structure of these modules is basically the same.

With such a design, Lin Hong only needs to focus on the 4-bit adder, realizes a total of 8 units, and then uses a transfer logic path to pass the results of the operation, and finally the final total result can be obtained.

After thinking about this, Lin Hong quickly drew out the logical design of the entire adder on the drawing.

After eating and replenishing energy, he continued to start the switching protein generator to produce the required switching protein in his brain.

The volume of these switching proteins is very small. Although they are molecular structure, their volume is much smaller than that of common molecules, with a diameter of only about 20 nanometers. Now Intel's latest CPU manufacturing process is 035 microns, that is, 350 nanometers.

Lin Hong produces these switching proteins in his brain. Although the amount is huge, the volume is small and can't be felt at all. However, he can still clearly feel the part produced by these switching proteins, which is located deep between Lin Hong's forehead and eyebrows.

This feeling is like he has generated a third eye. Lin Hong checked the information and speculated that this place is likely to be a place called "pine fruit body" in medicine.

pinealbady is located between the epithema of the brain and the thalamus. It is a reddish-brown bean-shaped body. It is a gray-red oval body with a length of 5-8mm and a width of 3-5mm, weighing 120~200MG. It is located at the top of the third ventricle, so it is also known as the cerebral gland.

The pine cones body is said to be a Western medicine. Lin Hong has also read the introduction in other books, saying that Chinese Taoists call this place the "eye of heaven", while the Buddhas call it "the sea of knowledge".

Lin Hong doesn't know why switching protein appears in this place, and he doesn't know what this place has to do with people's spiritual power. In short, the pineal gland is a very strange structure in the human body.

Lin Hong liked the saying of "Tianyan" very much, so he directly named the CPU of the superbrain system "Tianyan".

In the process of implementing the logic circuit and adder, Lin Hong's sequential circuit generator has been turned on, and the frequency is set at 133MHZ. This frequency is the working frequency of INTEL's latest CPU Pentium MMX. Although this CPU has almost been completed, it has not been completed yet. It is estimated that it will be officially launched in a month or two.

Just one day after the retreat, Lin Hong realized the adder.

This is already a relatively complex structure. Although focusing on the whole CPU, it is only the simplest component, just like a mechanical screw, but at the beginning, it was not easy to make screws. At the beginning, China even wanted this small thing. Imported from abroad.

The adder was made, and Lin Hong had a lot of fun.

He simply started by using 32 switching proteins to indicate the addition, and the other 32 switching proteins to indicate the addition, and then started the operation. In an instant, the switching protein used as the output changed and outputted an accurate value.

Lin Hong's observation results now still needs to count switches. For example, assuming that the result is 2, then the front is from left to right, the first 30 switching proteins are disconnected, the 31st is closed, and the thirty-second is also disconnected.

This was designed by Lin Hong himself. Although he knew that there must be no mistake in it, he was still happy to convert the decimal system to binary. After the calculation is completed, he converted the binary back to the decimal system.

Compared with the standard answer, the result is correct, and if you find it is correct, you will be very happy and excited.

This is a tedious and boring process. If people who don't understand see such a device in real life, they will definitely think it's just a toy.

However, it was such a toy in those years, and it finally became today's powerful computer. From doing mathematical calculations to heaven and earth, it is inseparable from its assistance.

Lin Hong redesigned the timing circuit. After adding the frequency modulation circuit, the drawings of the timing circuit were preliminarily determined. He concentrated the circuit diagrams on a small motherboard the size of a matchbox, whose energy source was a rechargeable battery, which was similar to that of a mobile phone, and then designed a relatively round appearance. The slippery shell can just fit the motherboard and the battery together.

Then Lin Hong sent the drawings to Pan Pan. However, he asked the factory to make him a batch of such devices. The first batch was 200 pieces, which were used as samples. The shell was required to use titanium alloy with very high strength, regardless of cost.

Although others basically can't understand anything when they get this drawing, in order to avoid trouble, Lin Hong asked Pan Pan to do this secretly. When looking for a factory for processing, it is divided into several steps, such as a manufacturer for motherboard printing, a manufacturer for welding components, a manufacturer for titanium alloy shell production, and finally The assembly is done by our own people.

Pan Pan didn't know what this thing was, but when he saw that Lin Hong was so careful and cautious, he naturally would not take it lightly.

At this time, he is no longer the time when he just graduated from high school. After such a long period of training, he has become much more stable. Due to the smooth development of tricolor fire technology, he has gradually met a lot of people and mastered some resources. It's natural to make something like this.

At present, three-color fire technology has become well-known in the industry, and the assembly machine market continues to grow. Three-color fire technology has a first-emptive advantage. It has not only won the agency rights of many brands, but also launched many cost-effective computer combination solutions. More importantly, the price of these assembly machines is more convenient than that of It is appropriate. For ordinary people, attraction is fatal.

In addition, Tricolor Fire Technology is the first company in the industry to publicly establish BBS. It has gathered a large number of computer enthusiasts on the forum, which has also promoted the sales of computers. However, BBS brings more of a foreign image to Tricolor Fire Technology, which makes everyone see that this is a serious and technological company. Before that, no company had such an open mind, and even put the after-sales problem on the Internet.

Lin Hong told Pan Pan to continue to increase the recruitment of technicians. The newly recruited employees can't let them rest. They need to constantly assign projects to them to do, in order to cultivate their technical ability.

Next, what Lin Hong has to do is to continue to complete other modules in the "Tianyan" CPU based on the adder, such as subtraction, multiplication and division, arithmetic logic unit, program counter, coprocessor, floating point calculation...

Although the project is huge, Lin Hong already has a very clear plan. It is only a matter of time to make it, and he no longer has no clue as before.

However, after all, the super brain is different from the computer, or there is a very big difference, and it cannot be directly copied. Lin Hong still has a long way to go to develop Tianyan smoothly. No module needs to be repeatedly designed and tested many times to finally find the best solution.

After Lin Hong sent the drawings to Pan Pan, he returned to the school dormitory. The next work did not need to be completed in the laboratory. He directly took the sample of the timing generator he made to the dormitory.
