A video game console is just a semi-finished product, it also needs a game card to be considered a complete game console, and in arcade, this game card is directly contained in the circuit board, if you want to replace the game, then you have to replace the entire circuit board, so, the cost of the arcade machine is the highest.

And now the personal computer is not an expansion slot, and there is no bus protocol for the expansion slot, all of which requires IBM to jointly launch the expansion slot based on the ISA bus after Intel launched the 286 chip, so the personal computer motherboard and arcade motherboard at this stage are a dense integrated circuit, especially read-only memory and random access, just like the army, a large piece of neatly arranged on the circuit board.

In the circuit structure of the arcade machine, there are 3 parts that require read-only memory and random access, and the first part is needless to say, it must be the microprocessor responsible for the core of game processing; The second part is the four-layer picture circuit that stores the synthesized game image, and the third part is the circuit that controls the sound, which is controlled by the image control microprocessor, which reads the data related to the sound or sound effect from the read-only memory and sends it to the special integrated circuit to synthesize the analog audio signal.

If that's the case, why not integrate all of these memories on a single circuit board and connect them to the motherboard via expansion slots? In this way, it can completely simplify the complexity of circuit design, reduce the size of the motherboard circuit, and by the way, it can also be used to save costs for customers, so that customers can be sticky to their products.

Moreover, the 3 parts that need memory, add up to a total of dozens of integrated blocks, made separately on a circuit board, not only to replace the game is convenient, copy the game of the four-layer picture is also very simple, only need to make a special program copy machine, soldered the blank memory of the circuit board into the machine, through the computer is very convenient to copy into the program, very suitable for mass production.

However, in order to simplify the number of pins in the expansion slot, a priority selection circuit must be added to this circuit board, so that nearly 40 data lines output by the four-layer picture circuit become 8-bit video data signal output through this selection circuit.

As a result,This circuit board and expansion slot have the possibility of realization.,I'm sorry.,IBM and Intel, which developed various standards for personal computers in the previous life.,Brother is about to take away the glory that belongs to you.,However,These standards are also very kind.,After registering a patent,All are promoted for free.,Anyone can use it.,Brother doesn't block everyone's money in these small details.。 Because, only if everyone adopts Ge's standards, then Ge will have the right to speak in this industry.

Ye Kai thought excitedly, picked up the white paper and pen next to him, and began to formulate the ISA protocol, since it is his own 'invention' standard, then it must not be copied from this name, Ye Kai didn't bother to use his brain to think of those lofty names, directly named the "P-1" protocol, and then named the 112 pins of the expansion slot of this protocol.

Of course, the expansion slot of the game console should not use so many pins, because the CPU is different, so the protocol must have changed, and it is called the "P-11" protocol, which is a standard for arcade games.

After these are done, Ye Kai began to draw the circuit block diagram of this circuit board on another blank piece of paper, as for the specific circuit schematic diagram and which integrated circuit pins need to be led to the expansion slot, that is the work of the hardware department, Ye Kai doesn't plan to use his own brain, so many employees under his hands, maybe this little thing can't be done?

Ye Kai put down the pen and paper, left the scratch paper full of words and block drawings on the side, picked up the circuit board, looked at the microprocessor chips of Motorola and Zilog on it unwillingly, and sighed in his heart, I don't know when I will be able to use my own chip?

Ye Kai had just finished sighing in his heart, when he smelled a smell of perfume belonging to a woman, and couldn't help but raise his head to take a look, only to see that he didn't know when, after reading the document, Roland had already walked to his desk, holding the manuscript paper that Ye Kai had just finished, and looked at it in surprise.

Can you not be surprised? Although Roland doesn't know much about the circuit of arcade games, after all, the circuit of the game console and the personal computer are figured out in many aspects, so when he saw the "P-1" protocol formulated by Ye Kai, he was very shocked, this protocol, for the future design of the personal computer motherboard, can not only simplify the circuit structure and mass production, but also reduce the complexity and difficulty of the circuit.

This will play an epoch-making milestone role in the design and production of personal computers!

Therefore, in addition to being shocked in his heart, Roland also felt a hazy spring heart for this handsome and handsome man. What's more, Roland is such a professional future beauty president!

"Boss, are these some of your ideas for the future of PC motherboards?" Roland asked Ye Kai excitedly, his blue eyes revealing a hint of imperceptible spring. "I'm getting more and more glad about my decision."

"Yes, this is just a very one-sided idea, and I need you to help me refine and improve." Ye Kai said modestly. "You've read the information, right? Tell us what you think. ”

"Boss, what I think doesn't matter for the time being." Roland restrained his careful thoughts and said. "The important thing is that I found a very important project in these materials, and if this project can be successful, we can launch our own CPU."

What the? Own CPU? Ye Kai was taken aback in his heart, he didn't know how many times he sighed for this idea today, he didn't expect that there would be a chance?

Ye Kai will not doubt Roland's exaggeration at all, after all, Roland's professionalism and work ability in his previous life are determined by history, and there will be no mistakes!

"Roland, what do you say?" Ye Kai suppressed the excitement in his heart and said. "What did you find?"

"In the data, I found out that the previous Atari company actually secretly designed its own 16-bit CPU, and it is expected that the CPU will contain 134,000 transistors, and the clock frequency can reach about 20MHz. It has a 16-bit internal and external data bus, a 24-bit address bus, and addressable 16MB of memory. Roland replied excitedly. Moreover, it has a great advantage over the 8088 chip launched by Intel Corporation last year. ”
