Based on the well-known common sense in the era of the popularization of smart mobile devices more than ten years later, this "6d" or "Liuhe" wireless data transmission technology is similar to the wireless technology standard bluetooth pioneered by Ericsson.

It’s just that the name comes from a Scandinavian king who is comparable to the Chinese Emperor Qin Shihuang's style-Bluetooth Harald. Don’t be embarrassed to be lazy and cut his beard, so he simply found such a king from Eastern culture. A noun, it also happens to describe its own wireless connection solution covering all directions from top to bottom, east to west, north to south.

In fact, this kind of lead is not a cut-off, after all, there is not much room for choice of civilian wireless communication methods, nothing more than infrared, shortwave and other types. And Zheru’s "6d" wireless connection technology solution uses the shortwave industrial_scientific_medical_band——ism frequency band for communication.

The so-called ism frequency band, as the name suggests, is mainly open to industrial-industrial, scientific-scientific, medical-medical, three major radio frequency bands. Institutions in related fields do not need licenses or fees when using these frequency bands, as long as they comply with certain transmission power limits, such as less than 1w, and do not cause interference to other frequency bands.

The rules formulated by the Radiocommunication Department of the International Telecommunication Union have different implementation conditions in different regions of the world.

For example, the United States has three frequency bands for the ism frequency band-902-928mhz, 2400-2484.5mhz and 5725-5850mhz; while Europe uses part of the 900mhz frequency band for gsm communication in the 2g era.

Fortunately, there is still a common rule reached, that is, 2400mhz, that is, 2.4ghz, which becomes the universal ism frequency band for all countries.

The microwave oven is a well-known example of the ism band application, and the microwave used for its high-frequency oscillation is 2.45GHz.

"6d" can also work in the 2.4ghz frequency band, and thus has a relatively easy to promote foundation.

Most of the people in the venue were veterans in the technical circle. Tang Huan woke up when he mentioned it casually, and then developed a keen interest in the "tidy desk".

There was a guy with a detached personality who wanted to use the microphone and joked: "Tang, are you too aggressive in environmental protection, and then developed the 6d wireless connection technology so that all cables can be killed?"

The richest man laughed and said: "In all fairness, regardless of cost, selling price and other factors, only from the point of use, compared to wireless connections, the benefits of cables in some cases, such as graphics, games, etc., are currently It's hard to be replaced."

Having said that, Tang Huan clicked the slide with a wireless mouse and switched to the page of comparing 6d and infrared communication technologies.

The biggest advantage of using infrared to transmit data is that it is simple and easy to use, and the implementation cost is low.

Zheru is quite authoritative in this application field, ranging from remote controls for home appliances such as TVs, VCRs, and air conditioners in the early 1980s to small mobile devices such as laptops, personal digital assistants, mobile phones, and even desktop computers. For example, data exchanges such as address books are covered.

Unfortunately, the limitations of infrared communication technology are also very obvious-due to the direct characteristics of infrared, it is not suitable for applications with many obstacles, and there are shortcomings with too short transmission distance and low transmission rate.

Pointing to the comparison table, Tang Huan used specific data to explain the reason for introducing 6d, "Infrared communication technology has a 15-degree minimum conical limit in angle, while Liuhe does not have this limit in the upper, lower, east, west, south, and north. In the application process, the typical sweet spot of infrared communication technology is the range of 5 cm to 60 cm from the transceiver, and Liuhe can reach 5 meters; in terms of transmission speed, the most supported mode of infrared communication technology is the lowest speed definition of rs-232— —9.6kbps, Liuhe can reach up to 720kbps."

"It can be said that in addition to the implementation cost, Liuhe has completely surpassed the currently widely used infrared communication technology, but as our experience suggests, this cost problem will be solved naturally as the scope of application expands."

"More importantly, everyone has seen that 6d can perfectly solve the interconnection problems between multiple devices-6d mouse, 6d keyboard, and the 6d printer that I will use soon can all be able to communicate with the host To communicate, and infrared communication technology is completely defeated."

After explaining this paragraph, Tang Huan tapped the print button on the 6d keyboard, and the 6d printer quickly spit out a comparison table of 6d and infrared communication technology.

Many engineers in the audience were full of admiration for Tang Huan, the Taishan Beidou with IT technology, so the atmosphere was warm and relaxed, so someone curiously asked: "Tang, you are the world's No. 1 under construction. Technology mansions, these wireless technologies must be applied."

Tang Huan nodded and replied earnestly: "We don't care about the gimmick of the world's No. 1 technology mansion hyped by the media for the time being. This project does have the mission of driving cutting-edge technology research and development-6d mainly provides a set of personal wireless local area network. Technical solutions, and true wireless local area networks, have more extensive communication functions."

Although the richest man was just a quick mention, many smart people immediately sketched the tip of the iceberg in the roadmap of philosophical technology research and development in their minds.

Seeing that everyone had digested the meaning of 6d, Tang Huan turned the topic to the support of Tang’s it Kingdom for 6d. “As you can see now, in the upcoming five-generation Fangyuan personal computer, The bottom layer provides driver support for 6d, striving to make it a standard configuration among notebook computer products; at the same time, 2g cellular mobile phone products are also an extremely important support platform."

"Of course, although the 6d technology I demonstrated to you just now seems to work normally, there is still a lot of work in areas such as low power consumption, low cost, anti-interference, compatibility, security, and industry promotion. It needs to be completed. I hope that through the formation of the widest 6d technology alliance, everyone can work together to solve these problems."

The Philosophy Developers Conference has developed into a pivotal technical event on a global scale. Therefore, during its holding, various media are paying close attention to any developments in it.

Undoubtedly, 6d, which appeared in the most vivid packaging of "beauty of simplicity", has become a star in technology news. Industry observers also analyzed that 6d, which can connect mobile devices such as mobile phones, PDAs, and laptops, is more like a pioneer of wireless LAN technology, and Tang Huan has a great plan.

6d, the popular fried chicken, not only brings you a freshness, the 6d technology alliance web site, which is almost online, has a group of well-known companies on its member directory page, which makes people have to admire Tang. The appeal of the richest man.

...

However, the rapidly popular 6d is not the most important technical topic at this Spring Developer Conference of Philosophers.

For a long time, compared with other microcomputers, the Fangyuan computer architecture has always occupied a leading position in technology.

Take the Fangyuan personal computer, the competitor ibm-pc, working in real mode, the code including the driver, etc., is rigidly defined to a fixed memory address space when it is loaded, and it is increased New features and new hardware have brought many restrictions.

For example, in the early 1980s, the size of the floppy disk drive was only about 360kb. In just a few years, it has evolved from 720kb and 1.2mb to the current standard 1.44mb. Even on this basis, 1.68mb and 2.88mb have been derived. Such niche specifications.

Let’s talk about another important internal memory—the hard disk. The 5-inch hard disk first equipped in the Fangyuan personal computer industry had a capacity of only 5mb. Now it is not only measured in hundreds of megabytes, but also 3.5-inch hard disks and 2.5-inch hard disks. They are popularized in desktop computers and notebook computers respectively.

In addition to the new functions brought by these new specifications, there are zip super floppy disks, cd-rom, usb, and the recent 6d wireless transmission standard, and even higher-end scsi, raid and other new technologies and new equipment have been added.

These new developments of personal computers by leaps and bounds require or similar implementations to provide the lowest level of support within a few seconds after the user presses the power button of the host. And these increasingly large number of system codes are limited by the insufficient memory address allocation space of ibm-pc in the design.

Tang Huan launched the fourth-generation Fangyuan personal computer mmx after the fourth-generation Fangyuan personal computer, and the fifth-generation Fangyuan personal computer has always been shrouded in a veil of mystery, because there is a big move related to the entire system in the research and development process. .

Fangyuan computer platform has an advantage that competitors can hardly match, that is, it can perfectly integrate cpu-central processor, dsp-digital signal processor, and other types of processors or hardware accelerators.

At this Philosophy Developers Conference, a new concept was proposed by Tang Huan. Compared with the traditional central_processing_unit-the central processor is the cpu, the graphics_processing_unit is responsible for graphics calculations-the graphics processor is the gpu. .

The richest man today did not show the "beauty of simplicity" of 6d, but used a traditional Fangyuan computer as a demonstration device.

When expounding the concept of gpu, Tang Huan’s tone was impassioned.

"We all know that the display output part of the main circuit board of the personal computer is only responsible for the auxiliary CPU at the beginning, which simply converts the digital signal into an analog signal and outputs it to the display."

"With the emergence of fonts with various artistic effects, as well as more extensive graphics and image processing needs, the burden on CPU display has increased significantly. Semiconductor chips with corresponding functions have naturally emerged as a matter of course. Until now, it has been quite mature. 2d accelerator."

"It's just that, although the functions of these display chips are becoming more and more powerful, even outstanding people have all the video generation functions including line drawing, area filling, block image transmission, and even a set of self-contained instruction sets, etc., and share Many tasks that could only be done by the CPU have significantly reduced the computational pressure of the entire system, but they have never been taken seriously enough to be regarded as an independent computing unit."

"Now, I think it's time to put forward the new concept of GPU, which will help everyone to have a clear understanding of the realization of computer graphics, and attract the industry to develop it into a vibrant industry, and promote the conversion of hardware coordinates and Light source, three-dimensional environment material mapping and vertex blending, texture compression and concave-convex mapping mapping, etc. The hardware implementation of the core technology of three-dimensional drawing operations in computer graphics theory~lightnovelpub.net~ usher in the 3d era as soon as possible Is coming."

"The next generation of Fangyuan computer platform will further integrate CPU, gpu, dsp and other processors with hardware accelerators to reduce the overhead of data scheduling and transmission between various components, so that these specialized chips can maximize the performance. effect."

"More specifically, programmable components like GPUs will be uniformly and transparently presented to programmers, which in turn enables personal computers to have considerable parallel processing capabilities."

"The benefits brought by this are self-evident. Ordinary users can get a better digital multimedia and electronic game experience."

"Even, we can also imagine that when the Internet is sufficiently popular, we can extend this parallel computing to the entire Internet, such as assisting in DNA cracking."

...

Tang Huan’s technical layout is still old and has successful experience to follow. After proposing the concept of gpu, Fangyuan’s computer platform integrates CPU, gpu, dsp and other processors with hardware accelerators, which is essentially equivalent to the original time and space. More than ten years later, opencl, cuda, firestream, and other general-purpose computing technologies will enable more powerful GPUs to handle other operations besides graphics operations.

In Tang Huan's view, the original development process of personal computers in time and space was determined by market interests rather than technological advancement. General computing technology should have been taken into consideration from the stage of infrastructure design.

With these most basic driving forces, maybe gameplay similar to Bitcoin mining can appear earlier.
