In Senxiale do not miss the ...... No, it was when I was discussing with my assistants and partners, and the E3 exhibition was gradually fermenting.

Unlike the Tokyo Game Show for players, E3 is a trade show for developers, resellers, platform providers, etc. - but in the future, the nature of E3 has gradually changed and it has become a game show that attracts the attention of the public.

This world line is also like this.

But that was before Senxia set foot in it.

After Senxia began to get involved, E3 was somewhat broken by Senxia.

Every day before the opening of E3, Senxia has to hold a grand press conference, and this game carnival directly turns the taste of the trade show into a carnival.

But what does it matter?

Pleasure is naturally the best.

However, some people at the scene were so happy, and some people at the Order of the Phoenix were not so happy.

While Mori Xia was working on the design, he had just completed tape-out for the next-generation GSII.

The GSII will use a quad-core CPU.

It is still a glue design, but it is a slight improvement compared to the current design, because there are two cores in each "glue chip".

In terms of design, according to Hitachi's suggestion, the part inside the chip was split, the IO control chip was separated, and two dual-core dies (chip cores) and one GPU core were placed in it, which became a four-point chip.

"Now let's see if it can be successful......" Tetsuro Fujiwara took a breath.

Tetsuro Fujiwara is a veteran employee who joined the Order of the Phoenix with Sega's development team.

He used to participate in the cooperation project with IBM, and now, he is in contact with Hitachi and other companies to develop new CPUs.

It's definitely not an easy job.

In fact, at the beginning, Senxia deliberately wanted to integrate all the cores on a die, because in this case, the internal architecture of the chip is the best, the design is simple and the latency is low, which can be said to be a very convenient design.

Therefore, after Hitachi and other companies came up with this four-point structure, Senxia did not approve of it.

In Senxia's view, except for the GPU, which is developed by another company and requires another "glue", it is better to integrate the others.

This design of four pieces of glue that hurts a little bit of egg pain will definitely not enter Senxia's eyes.

But at that time, it was Tetsuro Fujiwara who stood up and persuaded Mori Xia.

Tetsuro Fujiwara used a simple reason - product yield.

This kind of "glue" that splits the CPU, although it is a "glue", has a high product yield, and the improvement of product yield represents a decrease in product cost and an increase in production efficiency.

In the production of CPUs, it starts with a factory producing a large round wafer, which is then cut by people and the circuitry is carved into it.

In this way, the CPU becomes.

But when cutting wafers, there is a problem, that is, the wafers are round, and the chips are rectangular, which means that there will be waste in the corners of the wafer, and the smaller the core, the less waste.

It's not all.

On the wafer, not everything is perfect, and sometimes the core of the production may be damaged in one place.

The bigger the chip, the more so.

For example, if a chip with a high degree of integration is produced according to Senxia's idea, the cost may be $100, but if there is a problem on it, then the chip will be scrapped, the loss will be $100, and the entire chip will be scrapped.

But if it is cut into four small chips, one of them is damaged, so that the loss of the material costing $100 may only be $25, and the remaining three chips can still work.

Mori Xia was persuaded by Tetsuro Fujiwara's example.

- Glue is glue, just reduce the cost.

So, Tetsuro Fujiwara pitted himself.

He was promoted.

Promotions are a good thing. But after Tetsuro Fujiwara's appreciation, the problem to be solved will be great.

The yield and cost of the "glue chip" can be reduced, which is in the material.

But the design of this chip is not so easy.

If it is a fully integrated chip, the communication inside the chip is relatively smooth, which means that the product can save more resources.

The result is higher performance, lower latency, and easier resolution of internal conflicts.

But if it's glue, the coordination between each die is sometimes a big problem, and if one is not done well, it will lead to a sharp increase in the delay between the chips, and there are also problems with the coordination of work between dies and dies.

The manifestation of this is that it is easy to have a situation where one core is working, but the other cores are onlookers.

This is the mildest side effect. If the design is not good, there may be other problems, such as duplicate commands sent to the core, blue screens and errors caused by conflicts, and so on.

In other words, this glue design not only improves the hardware yield, but also slightly reduces the efficiency of the product, and the requirements for architects are increased by several grades, and the cost of design is actually increased.

And the person in charge of this part is Tetsuro Fujiwara.

GSII will be launched next year, and whether GSII can have a stronger "heart" depends on the results this time.

If the trial production of chips can be successful, then GSII will be found, and the development machine will be able to come out and be sent to other manufacturers within the year.

But if that doesn't work...... Congratulations, the product needs to be redesigned and taped out, and millions, or even tens of millions of dollars, will be wasted like this.

It is for this reason that Tetsuro Fujiwara is under a lot of pressure at this moment.

A promotion is indeed a promotion, but if you don't get this one right, it's quite dangerous.

But fortunately, Tetsuro Fujiwara knew that he was not the most nervous.

In Tetsuro Fujiwara's view, the most square ...... right now Actually, it's the handheld department.

The handheld department is now waiting for the new process to mature, and the concept prototypes produced before this will always be just prototypes.

What's more, the handheld sector can't replicate its previous successes.

You must know that if the CPU switches the process, even if it is just a process adjustment, the design of the CPU itself cannot directly adopt the original design, but needs to be adjusted on this basis.

In this way, it can be used effectively.

But because of this, this design is very exquisite.

But that doesn't mean Tetsuro Fujiwara is easy.

Because glue is not so easy to mix.

Of course, the so-called "glue multi-core" processor is not really filled with glue into the CPU, but a package of two kinds of die in one CPU, which has been said before, and will not be shown here for the time being.

The first to pioneer this and engage in commercial glue was actually Intel - this was the case with the Pentium Pro series they released in 1995. The Besturn Pro is the world's first processor to support more than 4GB of "super-large" memory, and it is also the first CPU to put the concept of "glue process" into practice.

It's just that Pentium Pro is not necessary for ordinary users, and commercial users who need it directly buy a motherboard with multiple CPUs (that is, a motherboard that supports multiple CPUs).

As a result, this ancient glue process was temporarily submerged in the sea of people.

Until another world line, the AMDX2CPU of the home adopts the "true dual-core" scheme.

But that's another dimension.

After I didn't touch the glue much, IBM has actually been silently developing it, otherwise Senxia wouldn't have been able to ask the other party for this technology.

"I've heard that the development of the next generation of PS consoles has begun. Just as Tetsuro Fujiwara was resting, a colleague came over with coffee.

"Got news?" Tetsuro Fujiwara was a little surprised.

"Well, after the news of our cooperation with IBM came last year, Sony also found IBM to develop a 'big guy', which Mr. Xia Sen speculated was the core of the preparation for the new generation of PS. ”

In the Order of the Phoenix, there are many people who are fans of Mori Xia.

There are book fans, game fans, and animation fans.

Behind the scenes, these people will also call Sen Xia "Teacher Xia Sen".

Well, in fact, a lot of this habit was learned by them and Company A, because there are many people in Society A who secretly call Sen Xia that.

"Sony's news is so poorly kept secret?" Tetsuro Fujiwara was a little surprised.

Sony's ability to keep secrets is not bad.

But...... However, Senxia is a "special channel"!

"I guess the document will come down soon, and I'll be able to see it then. ”

My colleague was right.

In the afternoon of the same day, Tetsuro Fujiwara got a non-disclosure agreement.

After signing the agreement, he saw some design materials for a game console.

But Tetsuro Fujiwara knew at a glance that this was not a next-generation game console developed by himself.

Because this machine is fundamentally wrong.

The tentative name "P" is based on the embedded Freebsd operating system, which is not correct at all - because it uses the Vista system.

The CPU of the game console is a processor codenamed "C".

This processor idea is also not in line with its own.

Senxia's route is similar to that of today's PC, which is the route of CPU+GPU, but Senxia takes the fusion route.

And this C processor is a single-core eight-coprocessor.

- That's right, that's the PS3 specs.

It's just a PS3 with another world line.

In this world line, a lot has changed.

For example, Sony found IBM to cooperate, in fact, some reasons were stimulated by Senxia's side, and part of the reason for their cooperation was because of the dual-core on Senxia GS.

As for whether there will be a PS3 with the same specifications in this world line, Senxia is actually not sure, because many of these things have changed - maybe someone else will come up with another PS3?

But although there is none, there is still reference value, so Senxia will take out this product that Sony may not have at home, and give it to you for a little reference.

C processor is the famous CELL.

But Tetsuro Fujiwara didn't know.

However, Tetsuro Fujiwara was a little surprised, because the architecture of this product is very strange, it is a single core, but there are 8 SPE (equivalent to coprocessor cores) CPU inside.

The main memory of the machine is 256MB.

"So small?"

Tetsuro Fujiwara muttered.

The product line given by Senxia here, the next-generation GSII, has a memory of 256MB.

But if the PS3 is only 256MB, this product is not an iterative upgrade product, and when it is launched in the future, it seems to be a little small.

——You know, on the product roadmap of your own product, when GSIII, the memory capacity of the entire product will reach 1GB!

According to Tetsuro Fujiwara's judgment, GSIII should be right for PS3......

"This should be the initial design and will definitely be adjusted later. He muttered.

Although his colleagues had revealed a lot of information before, he felt that even if the document was correct, it was not necessarily final—because what should be done when the product was established and the final product could sometimes be very different......
