Chapter 215 Be Our Own Processor
In 1989, the Mitsubishi Group of Japan acquired New York's Rockefeller Center for US$846 million, which was called the economic Pearl Harbor by Americans.
Before that, the economic prosperity had already made the right wing of the Little Japan country full of self-confidence.
In the 1960s and 1970s, with the support of the United States, the small country stumbled into the semiconductor industry.
By the 1980s, China's DRAM chips had controlled 80% of the global market. By 1988, cheap DRAM chips flooded the global market. Intel almost went bankrupt and was forced to lay off its DRAM storage division. Motorola and Micron were also forced to lay off more than 50% of their employees, and have been languishing ever since.
In the United States at this time, they were surprised to find that not only chips were defeated by Little Japan, but also the photolithography machines for manufacturing chips. Little Japan also firmly grasped the high-end market. The products of Nikon and Canon occupied the world's high-end optics market. 60% of the engraving machine.
"The United States is in trouble. They are lazy and lack vitality. Economically, the United States has collapsed!"
This is the consensus of the elite of China at this time.
In fact, this is indeed the case. Dark clouds are hanging over Silicon Valley. It seems that if there is a final kick, Silicon Valley will collapse.
Noboru Takeshita, the Prime Minister of Japan, said publicly at a government press conference: "The prices in Japan are too high, and the U.S. troops stationed in Japan have no money to go out on the streets. They can only spread AIDS to each other on ships..."
Takeshita Noboru's foreign minister was named Etsutaro. When reporting to Congress, he laughed and said: "The United States is the dog of the people of Japan. It is the country of Japan that paid these American soldiers to come here to guard their doors..."
Under such circumstances, Akio Morita found Japan's right-wing politician Shintaro Ishihara and wrote this book "Small Japan Can Say No"...
Well, Zhao Guoqing also admired the brain circuit of the little Japanese country. The United States was worried about how to find a reason to punish the little devil, and the little devil took the initiative to hand over the knife.
He shouted in need of a beating: "Come and kill me! Come and kill me, don't mean it..."
Teacher Xiao Zhao received a call from Motorola President Tommy and vividly described the scene just now.
"Mr. Zhao, haven't you seen that when the island left, it looked like a lost dog..."
"...?"
This sentence is still very inappropriate when it comes from Tommy, but you can also feel Motorola's resentment towards Xiaoriguo.
"Mr. Zhao, the people of Xiaori are clowns who steal technology. After they obtain the technology, they will kill everyone. I sincerely remind you that if the people of Xiaori seek technology from CITIC, please do not agree to them. History has proven that what I said!"
Um, Teacher Xiao Zhao is not satisfied with this. You Motorola has directed all your decisions to Zhongxun.
"...!"
President Tommy, I am a businessman. If the country can afford the price, I have no objection to providing WCDMA technology!
But he would not say this to Tommy.
Zhao Guoqing hung up the phone. It was so late at night, Tommy must have gone crazy...
Teacher Xiao Zhao was lying on the bed, unable to sleep, so he turned over.
Yang Qing next to him felt something strange and asked: "National Day, what's wrong?"
Zhao Guoqing said: "I was woken up by Tommy about work matters and I couldn't fall asleep!"
Yang Qing turned over, didn't say anything, just stayed there quietly, while her hand gently played with the little National Day.
Teacher Xiao Zhao was ignited, and ten minutes later, with a hearty and deep roar...the two fell asleep contentedly...
…
The next day, the office of the director of Institute 102...
Assistant Pan Chunhua walked into the office and said: "Director Zhao, Wang Yugang from ARM Company in the UK is back!"
Teacher Xiao Zhao raised his head, his eyes lit up, and said, "Let him come in quickly!"
Wang Yugang went to the UK to cooperate with ARM. Zhao Guoqing learned that ARM has designed five CPUs, ranging from ARMv1 to ARMv5. The mobile platform ARMv6 processor is currently being developed.
There are three IP licensing modes for ARM processors.
The first is processor authorization, which refers to authorizing cooperative manufacturers to use processors designed by ARM. The other party cannot change the original design, but can adjust the frequency, power consumption, etc. of the product according to its own needs.
The second is POP authorization, POP authorization (Processer Optimization Pack, processor optimization package), which is an advanced form of processor authorization. ARM sells optimized processors to authorized partners to facilitate their design and production of high-performance products under specific processes. Guaranteed processor.
The third is architecture authorization. ARM will authorize partner manufacturers to use their own architecture, and manufacturers can design processors according to their own needs.
What Teacher Xiao Zhao is interested in is the ARMv6 processor, which is a 32-bit processor with risc core architecture.
The standard version uses a one-micron manufacturing process, 800,000 transistors, a base frequency of 30 MHz, an 8kb data cache, and a 4kb instruction cache.
Unfortunately, the data cache and the instruction cache cannot be transmitted at the same time.
This is a processor with extremely poor performance for low power consumption, but it is also a processor with great potential for transformation.
32-bit ARMv6 includes SIMD, Thumb, Jazelle, DBX, VFP, and MMD instruction sets. Users can choose the instruction set they want. They even designed original MMD multimedia instructions, which can efficiently process some multimedia data.
Not only that, when ARM designed ARMv6, they fully considered the manufacturer's expansion of processors. They proactively designed the internal communication standard of the chip as the communication bus for each processing unit, and designed the data processing algorithm. In this way, If manufacturers feel that ARMv6 performance is insufficient, they can stack processing units, up to 16 processing units.
ARM has designed a topological structure for the processing unit, which can enhance the performance of the processing unit by adding structures.
Just like a display screen, in order to make the power consumption of the display meet the power consumption requirements of mobile devices, coupled with the limitations of the manufacturing process, ARM removed the color function of the display, adjusted the pixels to the lowest, and also adjusted the brightness to the lowest , only has the most basic display functions.
If you need the original performance, you only need to reset it.
Zhao Guoqing said to Wang Yugang: "Have we told ARM engineers about our needs? What did they say?"
Wang Yugang said: "Mr. Zhao, Dr. Sylvain Monsolo said that if we meet our needs, the manufactured processor can be used as an electric stove or can be used in the Arctic!"
Zhao Guoqing said: "How we use it is not his consideration. I need them to design the processor!"
What Zhao Guoqing means is to increase the number of floating point calculations to sixteen, the integer operation units to eight, the data cache and instruction cache, increase according to demand, and data and instructions can be accessed at the same time...
Wang Yugang said: "Mr. Zhao, Dr. Sylvain is here. He said he can accomplish anything impossible!"
This has cost money. The British economy is very bad, ARM has not many customers now, and the finances are quite difficult. We only need 80,000 pounds of business trip expenses to mobilize the enthusiasm of ARM's best engineers!
