Chapter 197 cpu, gpu and apu

Bob is a third-rate director at Universal, but he has changed his career this year. He is now a second-level agent for Dazzle TV.

I have to say that Dazzle TV is indeed very good. Such outstanding display effects are indeed unmatched by anyone now. There is no problem in meeting the general visual needs of families.

Although he is an agent for Dazzling TV, Bob's own home has only just installed a Dazzling TV.

Maybe it was because during those days when Hollywood was struggling to get up and down, Bob didn't like watching movies, he preferred to watch the news.

In particular, Catherine's Angel News Channel, which broadcasts 24 hours a day, is his favorite.

"...The Internet is a network composed of multiple computer networks connected to each other. People can communicate, transmit data, etc. on the Internet at any time. The network using optical fiber has excellent confidentiality performance. In the line

The possibility of being eavesdropped is almost non-existent, so it can be used in the military..."

Although it was already ten o'clock in the evening when Bob got home, when he turned on the TV, the hourly news had just started.

"...This plan will build a network that runs through the east and west of the United States, closely connecting the east and west..."

What is playing on the TV is an analysis of the White House press conference.

The term intercom is not new. In fact, there have been advertisements about intercom in California for a long time.

Although Bob left Hollywood, he still settled in Los Angeles.

"Hey, what a great little guy."

What Bob is talking about is Catherine.

The first time I got to know this girl was when I went to visit my old friend Homan. He thought Catherine's acting skills were pretty good, so he gave her a business card.

After that, Bob quickly forgot about the incident until Catherine actually started filming a movie, which made him remember this girl again.

Immediately afterwards, this girl soared into the sky and became the boss of a large company, which shocked people everywhere.

Bob originally thought that the girl named Catherine would eventually become a movie star, but the result was beyond his expectation.

"intercom..."

This thing does seem interesting.

…

The federal government showed off to the Soviet Union as a response to the other party's theft of information.

As for Catherine's project, it was quickly launched after preliminary planning.

According to the argument, one billion US dollars is definitely not enough.

But as long as the north-south route is connected, the rest will be easy to talk about.

Now, all Catherine has to do is to quickly fix this network.

However, Catherine was unable to help with specific technical issues. Regarding the fiber optic network, the matter had to be left to Ralph and Kao Kun.

Catherine has no control over the fiber optic network. She can only wait for good news.

These days, Catherine has taken out a lot of videos of Bruce Lee and various fighting masters, showing them to herself every day.

Although I already have a gun license, it is still very interesting to learn some self-defense skills.

Most of the techniques are performed with the feet, which is not stressful for Catherine. After all, she studied ballet before. Although Catherine's legs look very slender, they are very powerful.

But she didn't expect that the good news would come through in just a few days.

——16-bit CPU has been developed.

This 16-bit CPU has 18,000 transistors and can reach a frequency of 3mhz.

In order to commemorate this first 16-bit CPU, Catherine named it "fc", first-cpu.

Catherine's thinking is a little different from that of people of this era. People of this era like to study supercomputers and mainframe computers. Even Olson's previous company mainly focused on the research of small computers - so-called minicomputers.

The size is also huge.

Catherine thought that she had squeezed out the name fc. Maybe it would be interesting to name her CPU fc.

Of course, this fc is somewhat different from the historical family-uter.

The meaning of this CPU is "first hit". Catherine will soar into the sky with the 16-bit CPU.

Of course, the performance of fc is still a bit poor. Catherine's second 16-bit CPU plan is sfc, which is super-first-cpu.

Catherine thought this meaning was very good. Of course, people of this era would not know what this was about.

Catherine's goal has always been personal computers.

Even the Internet is, in a sense, a tool that serves personal computers.

In addition to this good news, there is also bad news.

——IBM introduced the floppy disk.

To be precise, this was a 32-inch giant floppy disk with no practical value at all, but for Catherine, the news was not very good.

The emergence of floppy disks will change the entire computer market. This type of disk occupied the entire market until it was replaced by USB flash drives.

Fortunately, IBM seemed not to pay enough attention to personal computers and gave Catherine more time.

At this time, Catherine also started her own new plan. First of all, she wanted to meet the legendary Eight Rebels.

they are--

Robert Noyce, Gordon Moore, Julius Blanc, Eugene Clare, Kim Hurney, Jay Rust, Sheldon Roberts and Victor Greenick.

Historically, they couldn't stand Fairchild's unlimited transfer of profits to the parent company, so they left the company one by one in anger.

In this era, because Fairchild Company's profitability became stronger, conflicts broke out in advance. Because of this, the Eight Rebels also left faster.

As soon as they walked out of the door, Catherine pulled them to the intel next door.

——Katherine has been paying attention to and instigating rebellion against them.

"Hello everyone."

Catherine received them in the drawing room.

"Hello, Miss Edson."

Compared with history, these eight people are still very young.

Perhaps because of the change in status, they still seem to yearn for Intel, the holy land of semiconductors.

"Welcome to the Intel family."

Sanders smiled.

All eight people were clearly very excited.

At this time, Catherine glanced at the eight people, especially Robert Noyce who proposed light calculation, and the legendary Gordon Moore.

However, Catherine almost stopped laughing at this scene.

The "historical" president of AMD welcomes the leader of Intel, who has been suppressing him, to join the Intel company of the current Ark Group...

After meeting them, Catherine returned to her office and asked Sanders to receive them. If she stayed there any longer, Catherine might actually laugh.

Because of the addition of the Eight Rebels, Catherine's ambitions have become even greater.

The development of GPU was put on the agenda, but Catherine soon thought of APU.

APU, the full name is elerated-processing-units, and its Chinese name is acceleration processor. Historically, it is a product of AMD's convergence concept. It is the first time that the processor and independent graphics core are built on one chip. It has high performance at the same time.

The processing performance of the high-performance processor and the latest independent graphics card supports "accelerated computing", greatly improving computer operating efficiency and realizing the true integration of CPU and GPU.

Historically, after AMD launched the APU, Intel laughed at it. But later, Intel saw that this product was very good and began to secretly study it.

Finally, they quietly launched their own core graphics CPU and integrated the graphics card into Intel's CPU.

However, this one is no longer called APU. Intel changed its name to - but as far as Catherine is concerned, he still thinks APU sounds better.

But even in Catherine's era, APU was still not as good as the combination of CPU and GPU.

The reason is mainly because the technology of CPU has always lagged behind that of GPU.

In fact, Intel, a latecomer, has done worse than AMD. After all, in Catherine's era, AMD acquired ATI, a company that produces graphics cards. As for Intel's core graphics cards, the advertising is very flashy, but in use... then

It’s just whoever uses it knows.

Although future GPUs still have advantages. But in Catherine's view, if APU is at the same technical level, it still has a great advantage compared to the combination of CPU and GPU. Even if the graphics card has CUDA technology that can afford CPU computing, it is still better than the combination of CPU and GPU.

Not the integrated apu.

The integration of apu is divided into four parts.

The first step is the physical integration process, which integrates CPU and GPU on the same silicon chip, uses high-bandwidth internal bus communication, integrates high-performance memory controllers, and promotes heterogeneous computing with the help of open software systems.

Integrating them together can increase the transmission rate between the two. This one is better than separate CPU and GPU.

The second step is platform optimization, the interconnection interface between CPU and GPU is further enhanced, and bidirectional power management is unified.

——This part is the most critical.

The third step is architectural integration to achieve unified CPU/GPU addressing space, GPU uses pageable system memory, GPU hardware is schedulable, and CPU/GPU memory is coordinated.

The fourth step is architecture and system integration. The main features include GPU computing environment switching, GPU graphics priority computing, PCI-E collaboration with independent graphics cards, real-time integration of parallel task running, etc. These require software support. Of course, Catherine herself

It is the largest software provider.

Good steel is used on the blade, this saying is very good.

Talents should also be used wisely, this is Catherine's idea.

Of course, in the era without 3D, GPUs were of little use, let alone APUs.

The core of the graphics card that Catherine plans to use on the next generation of personal computers is 2d-renderer, which is a 2D renderer.

Catherine's requirements are not high. She hopes to achieve 4096 color display within the next two years, which is enough. As for enhanced color and true color... it is too early to say.

Catherine wrote the plan for the accelerated processor, and then gathered the Eight Rebels to form a new research group. She wondered whether she could set up a laboratory in the future. If it could be independent, it might be more efficient.
