Chapter 688: The technological innovation of personal computers

Through the research and development of Hanxin No. 1, Gong Ni and others have mastered the internal structure and design process of the chip. The team they led has thoroughly understood the design of the CPU. Then, specializing in the development of DSP chips will also be more effective.
Now, working with the 114 Institute in joint research and development, it is certainly much better than using a general-purpose CPU. With the help of Hanxin Technology, the research and development will definitely reach the goal soon.
The director nodded: "If possible, great, we will immediately appoint dedicated personnel to form a team!"
Nigong nodded: "Mr. Qin, we can too, and we plan to continue research and development of several chips in the next step. For example, it is not enough for us to have only the CPU, and there are matching north and south bridge chips."
For a qualified computer, only a powerful processor is certainly not enough.
If a computer motherboard takes the CPU socket as the north, the connecting chip close to the CPU socket is called the "North Bridge Chip".
The north bridge chip is the chip closest to the CPU on the motherboard. This is mainly because the communication between the north bridge chip and the processor is the closest, and the transmission distance is shortened in order to improve the communication performance.
The north bridge is used to process high-speed signals, usually CPU (processor), RAM (memory), AGP port or PCIExpress, and the communication between the south bridge chip.
The south bridge chip is located on the motherboard far below the CPU slot, in front of the PCI, that is, the side in front of the main box. This layout takes into account that it is connected to more I/O buses, which is farther away from the processor. Conducive to wiring.
The South Bridge chip is responsible for the communication between I/O buses, such as PCI bus, USB, LAN, audio controller, keyboard controller, real-time clock controller, advanced power management, etc.
Now, the Hanxin No. 1 chip has been built. After having such a chip, it is absolutely a waste to continue to use the existing North and South bridge chips. Therefore, Gong Ni has also made a series of plans.
Even the CPU is there. Others are not trivial?
"Of course it can, and the head office will strongly support it." Qin Guan said: "If the funds are not enough, the head office can further invest in the research and development of these projects. The head office will also support the required technology."
In terms of technology, you can exchange those technical materials yourself, which can greatly accelerate the speed of research and development.
As long as the computer of Hanxin Technology Company appears, L Xiang Group should know that it has to work hard, right?
Whenever there are difficulties, as long as you talk to Qin Guan, Qin Guan will definitely come to solve them.
"We still have one last problem." Then, Gong Ni continued to speak: "It is our storage problem. With floppy disks, we can't store the new operating system, and the existing hard disk is too bulky."
As the performance of the CPU improves, peripheral peripherals need to be synchronized to improve, and chip problems can all be solved. Then, the last problem is how to store it.
The computer that L thinks now uses a floppy disk, which is the most economical thing, but the capacity is pitiful.
In the beginning, the computer storage method was a magnetic drum. Later, a hard disk appeared. In 1956, IBM manufactured the world's first hard disk.
The disc diameter is 24 inches, the number of discs is 50, and the weight is hundreds of kilograms, which is equivalent to the volume of two refrigerators. But its storage capacity is only 5MB.
Although the volume is too large and the performance is inefficient, compared with the magnetic drum, the performance has been developed by leaps and bounds. Since that time, IBM has taken the lead in this area.
Just in 1973, IBM proposed the "Winchester/Winchester" technology and successfully developed a new type of hard disk IBM3340. This kind of hard drive has several coaxial metal discs coated with magnetic material. They are sealed in a box together with a movable magnetic head, and the magnetic head reads changes in magnetic signals from the rotating disk.
This structure is very similar to the hard disk structure of later generations. It is the ancestor of the hard disk of several terabytes in later generations.
Just this year, IBM invented thin film magnetic head technology, which can significantly reduce the distance between the magnetic head and the magnetic sheet and increase data density. The volume of the hard disk can be further reduced, the read and write speed can be faster, and the capacity is larger.
For example, the first truly gigabyte-capacity hard drive finally appeared, with a capacity of up to 2.5GB. It seems more than enough.
However, although the capacity has increased, the volume remains the same. It is still a large device like that of a refrigerator. It can't fit in a personal computer at all. At the same time, the price is high and it cannot be used by individual users at all.
Ni Gong has trouble in this regard. If you launch a window operating system, you will have to use five or six floppy disks. Each time you start the computer, you must insert these floppy disks in turn, which is quite cumbersome.
What about the hard drive? It's too heavy.
Qin nodded his opinion: "This is indeed a problem, but we don't have to worry too much. We can research and develop our computers while seeking international cooperation. Perhaps we can know the hard drive for our personal computers."
Qin Guan is not worried, because he remembers the history of later generations. Just next year, a company founded by two former IBM employees developed and launched the first 5.25-inch hard drive ST-506. Although the initial capacity of the hard drive is only 5MB, this It is the first hard drive product for individual users.
This is the famous Seagate company in later generations. In other words, don’t look at the problem that you are currently limited to storage, but it will be resolved soon, which coincides with the time of Seagate’s hard disk next year. When the operating system is developed, add the hard disk control program. , You can fully mature.
At that time, it will definitely be a sensation.
By the way, when the Godson-1 was released at the time, but it was proposed that the Godson-2 was to be built by the end of the year, do you want to play the game?
Qin Guan suppressed this idea, um, time will prove everything, he still needs to be a kind person. If L wants to eventually go bankrupt due to poor management, he can try to acquire it.
Before entering the factory for inspections, Qin Guan had already begun to arrange many specific matters. Now, Qin Guan is full of enthusiasm and is ready to continue wearing dust-proof clothing, but he has received new news that the delegation of David’s country has come to Han country!
It is Qin Guan's unshirkable responsibility to receive representatives of the Kingdom of David, and it is also Qin Guan's task to deceive the representatives of the Kingdom of David. Therefore, Qin Guan looked at the gate of the workshop where he was about to step into, and stopped, go back, and can't neglect the guests. As for the company, he will come again later when he has time.
"After our personal computers are built, we will give priority to satisfying the domestic market, especially scientific research units." Before leaving, Qin Guan made a decision again.
L can’t wait to make a big hit. The world is famous and the price of the product is very high. Qin Guan doesn’t care about this. His own products must first meet domestic demand and contribute to the country’s technological development!
