Chapter 418: A "brand-new" 486
However, PKUnity86-3 is a strange thing,The reason why I say this,This is because it is a processor that uses both MIPS and X86 dual architectures,The two architectures exist in a processor at the same time,The manifestation is,It has a built-in X86 microprocessing core,A MIPS architecture microprocessing core,In addition, there is a GPU display core、Sound card core、Network card core、 USB and ps2 and other computer external interface processing core multimedia processing and computer management core, these three independent core integration in the same chip, of course, seems extremely strange, and its purpose is to turn this MIPS processor into a processor that can be compatible with the indos operating system to a certain extent.
Obviously, if it is only positioned to serve the X86 architecture, then it does not need to be born at all, after all, the K6 and Pentium 2 level processors have been reduced to antiques in 2014, and were thrown off by Intel's latest generation Core i7 or AMD's Super Pile Driver FX9590 processor at that time. The birth of y86-3 is mainly to enable the MIPS processor to run under the INDOS operating system, so as to realize the execution of programs under the MIPS architecture on the computer with the indos operating system.
This can be seen from its customers, which are basically customized laptops and embedded computers for some enterprises and units, such as military rugged laptops or on-board computers. These customers can install some special versions of the INDOS operating system on military laptops, for example, and use the INDOS graphical interface to operate the software under the MIPS architecture and run on the MIPS microprocessor core inside the processor.
Therefore, in order to achieve security, Beizhong Chronicle carried out a large-scale investigation of all the microstructures on the X86 instruction set microprocessing core in this processor, and redesigned all the microstructures that could not be figured out, and eliminated the backdoor left by Western processor companies in the design, so as to eliminate the hidden risks.
What Hu Yiting did was very simple, that is, to take out the X86 architecture microprocessor core designed by Beijing Popular, first castrate the floating point coprocessor computing core included in the original design, and then castrate the architecture design of the Pentium processor that belongs to the Pentium processor in the X86 computing core similar to the Pentium MMX or K6 level, and only retain the built-in 486 processing core, because the 486 chip does not need a multimedia instruction set at all. Of course, if you need it in the future, you can add this part of the castrated design module to it, anyway, it was originally deleted from it, and it will be seamless to put it on it in the future.
Then when the time comes, this 486 can be smoothly upgraded to Pentium MMX or K6 level processor, which can be described as a smooth upgrade.
Originally operating at 1.8GHz and 40nm process, this chip has excellent power consumption control, with a peak power consumption of only 5, which is a typical embedded processor suitable for laptops and in-vehicle system computers that need to control power, such as radar vehicles, missile vehicles or command vehicles.
Hu Yiting's work this time is just to copy the simplest of the three cores,That is, the X86 microprocessing core that has been safely redesigned by the Beijing Mass Chronicles with all the microstructures,And it's not all copied,After all, after castrating a coprocessor,There's not much left,After a little adjustment on the wiring,You can use it directly,The original 40nm process design,It can be easily scaled up to 0.8 micron process for production,After all, the process amplification is much smaller than the difficulty of process reduction。
In the design process of this chip, Hu Yiting continues to save on the company's internal server every day, and saves the daily design progress as a new file, so the colleagues of the processor division can follow up its design every day.
It's like someone else has solved the answer to a math problem, and it takes you longer to understand the answer than someone else has to solve the problem. And this process continued until the end of the 486 design!
Regarding Hu Yiting's performance, Wu Shihuan and Jiang Yunshun, two old friends who had seen him design the Shadow Overlord at the Computing Institute, were not surprised, and said: "A strong life does not need to be explained. The rest of the engineers deeply imprinted the name of Hu Yiting's genius in their hearts, and felt that as long as Chongguang was led by him, he could do anything!
The internal technical conference was held for three days, and Hu Yiting asked the engineers of the processor project team to come to the stage one by one to sort out and elaborate on all the microstructures in the design, but he sat in the audience to listen.
The reason is that he copied it too quickly, and he didn't remember the functions of the design everywhere too much, and he didn't have the time to understand it thoroughly, so he simply took this opportunity to discuss with you and gain an in-depth understanding of the 486 processor he designed.
Fortunately, everyone is more tired than him these days, and everyone in the processor division is working overtime almost every day, and they don't dare to ask him and disturb his research and development progress, so they have to keep discussing and understanding his design in groups.
So at this time, everyone was very excited, thinking that Hu Yiting was going to test their knowledge, so they all came to the stage with panda eyes in high spirits, elaborated the results of the team's discussion one by one, and helped Hu Yiting review the design of this 486 processor in detail.
After the meeting, everyone agreed that Mr. Hu used his unparalleled genius wisdom to single-handedly carry out a deep redesign of the 486 processor into the microstructure, completely sweeping away all the dead ends in this processor, this product can be called the 486 processor with independent intellectual property rights, is a "brand-new" 486, the reason why he is new is that it is in its microstructure design. And based on this, this is a product that can be called perfect security, and should be the first choice of the Chinese government and defense and even all levels of industrial departments, especially suitable for all kinds of embedded applications.
As for the specific power consumption and working frequency of this 486 processor, it will not be determined until the chip is projected, but everyone has reached a consensus through discussion and research these days, this 486 processor that uses many new microstructures, must have a good performance in terms of frequency and power consumption.
Hu Yiting also realized this through the comprehensive combing and in-depth review of this meeting, and found that many of the microstructures in this 486 processor have adopted advanced designs, and can apply for at least more than 100 IP core patents, many of which seem to be the classic designs of Quanmeida in the previous life.
Thinking of Quanmeida, Hu Yiting felt sorry in his heart, it was a company that embarrassed Intel in low-power IP design, and had a unique solution in the chip design of software and hardware, so that after Intel acquired them, they successfully made the famous Core series processors known for their high performance and low power consumption. But these are all later words, not to mention for the time being, Hu Yiting just flashed in his mind, and then refocused on the work in front of him.
Next, Hu Yiting gave everyone a day off, there is nothing more precious in the world than health, Hu Yiting feels that the health of the staff is as important as his own.
These days, everyone accompanies him to serve this 486 processor day and night, and he is too tired, and he really needs to rest and relax.
