Advantages of biological computer

1983, the United States put forward the concept of biological computer. Since then, various developed countries have begun to develop biological computers. Biologists have applied bionics to the field of biological computers, resulting in the viewpoint of biochemical molecular framework biological computers. At present, the biological computer is still in the stage of vigorous development, and new biochips are being actively developed at home and abroad. Although the biological computer has not made significant subversive progress, some scholars even pointed out a series of shortcomings of the biological computer, such as the interference of external environmental factors, the undetectable calculation results, and the failure to guarantee the success rate of biochemical reactions. In addition, it is difficult to run a text editor on a chip based on protein molecules. However, these problems will not affect the rapid development of bio-computer, a very tempting field. With the continuous progress of human technology, these problems will eventually be solved, and the commercialization of biological computers will come.

Biocomputer is the subject with the most vitality and development potential in the global high-tech field. This kind of computer involves many disciplines, including computer science, brain science, molecular biology, biophysics, bioengineering, electronic engineering and other related disciplines. Its main raw material is protein molecule produced by bioengineering technology, which is used as biochip. Biocomputer chip itself also has the function of parallel processing, its operation speed is 654.38+ million times faster than that of the latest generation computer, its energy consumption is only one billionth of that of ordinary computer, and its information storage space is only one billionth. Biocomputers have many advantages, mainly in the following aspects:

1. Small size and high efficiency.

The area of biological computer can accommodate hundreds of millions of circuits, which is hundreds of times higher than that of current electronic computers. At the same time, biological computers that no longer have the appearance of computers can be hidden in places such as table corners, walls or floors, and at the same time, heating and electromagnetic interference are greatly reduced.

2. Persistence and reliability of biochips.

Biocomputers are permanent and highly reliable. If the repair mechanism of the organism itself can be exerted, it can repair itself even if the chip fails. This is an attractive potential advantage of biological computers. ) protein molecules can self-assemble to generate new microcircuits, which are active, so biological computers have biological characteristics. Biological computers are no longer like electronic computers, which cannot automatically repair damaged chips. Biocomputers can play a biological adjustment function and automatically repair damaged chips. Therefore, the bio-computer has high reliability, is not easy to be damaged, and can be automatically repaired even if the chip fails. Therefore, the bio-computer chip has certain durability.

3. Storage and parallel processing of biological computers

Compared with traditional electronic computers, biological computers have great advantages in storage. One gram of DNA can store as much information as one trillion optical disks, and the storage density is 654.38+000 billion to 654.38+000 billion times that of common disks. Biocomputers also have super parallel processing capabilities. Logical operations can be realized by biochemical reactions in narrow areas, and tens of billions of DNA molecules constitute a large number of DNA computers for parallel operations. In particular, biological neural computers have good parallel distributed storage and generalized fault tolerance. It shows great potential in dealing with Boltzmann automaton model and some non-numerical problems. Really let go of the von Neumann model and realize intelligence.

The data transmission and communication process of biological computer is simple, and its parallel processing ability can be comparable to that of super electronic computer. The different arrangement order of DNA molecular bases is used as the original data of the computer, and the corresponding enzymes can perform basic operations on DNA bases through biochemical changes, which can realize various functions of the electronic computer.

Biocomputers contain a large number of genetic material tools, which can perform millions of calculations at the same time. The traditional electronic computer tests all possible solutions one by one at the current speed, and the biological computer processes all the molecules in each molecular library at the same time, instead of analyzing the possible answers one by one. An electronic computer is equivalent to having a string of keys, and unlocking with one key at a time, while a biological computer uses millions of keys at a time, and the calculation speed will be1100,000 times faster than the existing supercomputer. The number of operations of a biological computer can be as high as one second or more. Further development and combination with other high and new technologies will have broad prospects.

4. Heating and signal interference

Biocomputer components are biochemical components composed of organic molecules, which work by chemical reactions, so; It only needs a little energy to work, so it won't be like an electronic computer. After working for a period of time, the body will get hot, and there is no signal interference between the circuits of the biological computer.

5. Data error rate

Another important property of DNA chain is the double helix structure, in which base A and base T, base C and base G form base pairs. Each DNA sequence has a complementary sequence. This complementarity is the unique advantage of biological computers. If there is an error in the double helix sequence of DNA, the modifying enzyme can refer to the complementary sequence to repair the error. Double helix structure is equivalent to RAID 1 array of computer hard disks, and one hard disk is the mirror image of another hard disk. When the first hard disk is damaged, you can repair the data through the second hard disk. The biological computer itself has the characteristic of modifying errors, so the data error rate of the biological computer is low.
