Chapter 877 Innovate and Decisively Occupy the Pit

...

Judging from the common sense in the era of popularization of smart mobile devices more than ten years later, this "6d" or "Liuhe" wireless data transmission technology is similar to Bluetooth, the wireless technology standard pioneered by Ericsson.

However, this name comes from a king in Scandinavia who is comparable to Qin Shihuang in China-Bluetooth Harald. Tang it was embarrassed to be lazy, so he simply found such a king from the oriental culture. The noun also just describes the all-round coverage of its own wireless connection solution up and down, east, west, north and south.

In fact, this kind of one step ahead is not considered a cut-off. After all, there is not much room for civilian wireless communication methods, which are nothing more than infrared rays and short-waves. 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. Organizations in related fields do not need licenses or fees when using these frequency bands, as long as they abide by a certain transmission power limit, such as less than 1W, and do not cause interference to other frequency bands.

The rules formulated by the Radiocommunication Sector of the International Telecommunication Union are implemented differently in various 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, which is 2.4ghz, has become the common ism frequency band in all countries.

The microwave oven is a well-known application example of the ism frequency band, 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 promotion basis.

Most of the people in the venue were veterans in the technology circle. When Tang Huan mentioned it casually, they all came to their senses, and then became very interested in the "tidy desk".

There was a guy with an out-of-the-ordinary personality who asked for the microphone and joked: "Don, are you too aggressive in environmental protection, so you developed the 6d wireless connection technology to kill all the cables?"

The richest man smiled and said: "In all fairness, regardless of factors such as cost and selling price, only from the point of use, compared to wireless connections, the benefits of cables are in some cases, such as drawing, games, etc., are currently Hard to replace."

Speaking of this, Tang Huan clicked on the slide with the wireless mouse, and switched to the page comparing 6d and infrared communication technology.

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, from the remote control of household appliances such as TV sets, VCRs, air conditioners in the early 1980s, to small mobile devices such as laptops, personal digital assistants, mobile phones, and even desktop computers. Data exchanges such as address books have been covered.

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

Pointing to the comparison table, Tang Huan explained the reason for launching 6d with specific data, "Infrared communication technology has a minimum conical limit of 15 degrees in angle, while Liuhe does not have this limit in the up, down, east, west, north, south; in reality 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 the distance 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, and the highest speed of Liuhe can reach 720kbps. "

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

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

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

Many engineers in the audience had admiration for Tang Huan, the Taishan Beidou of IT technology, so the atmosphere was warm and relaxed, so someone asked curiously: "Tang, your world's number one under construction High-tech mansions must use these wireless technologies.”

Tang Huan nodded, and replied seriously: "Let's ignore the gimmick of the world's number one high-tech mansion hyped by the media for the time being. This project does have the mission of stimulating the research and development of cutting-edge technologies - 6d mainly provides a set of personal wireless local area network. Technical solutions, and the real wireless local area network has a wider range of communication functions."

Although the richest man only mentioned it superficially, many smart people immediately sketched out the tip of the iceberg of the roadmap for the research and development of Zheru technology in their minds.

Seeing that everyone had almost digested the meaning of 6d, Tang Huan changed the topic to Tang's IT Kingdom's support for 6d, "As you can see now, in the upcoming fifth generation of Fangyuan personal computers, there will be At the bottom, it provides driver support for 6D, and strives 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 be working normally, there is still a lot of work to be done in terms of low power consumption, low cost, anti-interference, compatibility, security, and industry promotion, etc. It needs to be done. I hope that by forming the widest range of 6d technology alliances, everyone can work together to solve these problems."

...

Zheru Developer Conference has developed into an important technical event in the world, so during its holding period, various media are paying close attention to any developments in it.

Undoubtedly, 6d, which debuted in the most vivid packaging method of "beauty of simplicity", has become a star in the technology news. Some industry observers pointed out that 6d, which can connect mobile phones, PDAs, laptops, and other mobile devices, is more like a pioneer in wireless LAN technology, and Tang Huan has a lot of plans.

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

...

However, the rapidly becoming popular 6d is not yet the most important technical topic at this Zheru Spring Developers Conference.

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 among them as an example, the competitor ibm-pc works in real mode, and the codes, including drivers, etc., are hard-defined to a fixed memory address space when loaded, adding New features and new hardware have brought a lot of restrictions.

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

Let’s talk about another important internal memory—hard disk, the 5-inch hard disk first equipped in the Fangyuan personal computer industry. It is widely used in desktop computers and notebook computers respectively.

In addition to the new functions brought by such new specifications, new technologies and devices such as zip super floppy disk, cd-rom, usb, and the latest 6d wireless transmission standard, and even higher-end scsi, raid, etc. have been added.

These rapid new developments in personal computers all require or similar implementations that provide the lowest-level support for a few seconds after the user presses the host's power button. However, these increasingly large number of system codes are limited by the insufficient memory address allocation space in the design of ibm-pc.

After the fourth generation of Fangyuan personal computer, Tang Huan launched the fourth-generation Fangyuan personal computer mmx, which seems to be a transitional product. The fifth generation of Fangyuan personal computer has always been shrouded in a veil of mystery, because there is a big move in the development process that concerns the entire system. .

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

At this Zheru Developers Conference, a new concept was proposed by Tang Huan. Compared with the traditional central_processing_unit——central processing unit, or cpu, the graphics_processing_unit, which is specially responsible for graphics computing——graphics processing unit, or gpu .

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

When explaining the concept of gpu, Tang Huan's tone showed a kind of impassioned

"We all know that the display output part on the main circuit board of a personal computer was originally responsible for assisting the CPU, simply converting digital signals into analog signals and outputting them to the display."

"With the emergence of fonts with various artistic effects, and the need for more extensive graphics and image processing, the burden on the CPU for display has increased significantly, and semiconductor chips with corresponding functions have emerged naturally, 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, and even outstanding ones have all video generation functions including line drawing, area filling, block image transmission, and even a set of self-contained instruction sets, etc., share the A lot of work that can only be done by the cpu has obviously reduced the computing pressure of the entire system, but it has 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 have a clear understanding of the realization of computer graphics, and attract the industry to develop it into a vibrant industry, promoting hardware coordinate conversion and Light source, three-dimensional environment material texture map and vertex blending, texture compression and concave-convex mapping texture, etc. are still in the hardware implementation of the core technology of 3D graphics calculation based on computer graphics theory, so as to usher in the 3D era as soon as possible.”

"The next-generation 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 exert their maximum potential. effect."

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

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

"We can even imagine that when the Internet is popular enough, we can extend this kind of parallel computing to the entire Internet, such as assisting in DNA cracking."

...

Tang Huan's technical layout is still old-fashioned and has successful experience to follow. After proposing the concept of gpu, the Fangyuan 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 allow GPUs with more powerful performance to handle other operations besides graphics operations.

In Tang Huan's view, the development process of personal computers in the original time and space was determined by the pursuit of market interests, not by the advancement of technology. General-purpose computing technology should have been considered from the infrastructure design stage.

With these most basic driving forces, maybe games like Bitcoin mining can appear earlier.
