Important changes in the electronics industry (1)

With the separation of software and hardware, an important change has occurred in the electronics industry. Vertical integration from the original company

Integrating the entire industrial chain is "vertical integration", which has become "horizontal integration"-that is, each enterprise

Both join the global supply chain and find their own division of labor and position.

Let's start with an American, his name is von Neumann. Is an amazing mathematician, he proposed "Von ·

Neumann structure", so it is called "the father of computers."

Regarding the "von Neumann structure", where is the groundbreaking? If an electronic product wants to work normally,

It is nothing more than inputting a signal or data, and then processing the signal or data. For example, a radio, input through the antenna

The radio wave signal sent by the radio station is processed inside the radio and turned into a sound that can be heard by human ears.

Play it out.

When you turn on the radio, there are various electronic components, such as transistors, resistors, capacitor, etc.

. These components are combined to become a circuit; more complex combinations are integrated circuits.

The characteristics of the previous electronic products we are talking about are: a single purpose, a radio is a radio, and a TV is a TV.

The telephone is a telephone, which is very different and cannot be mixed. Because their internal hardware is different, the signal processing process

The order is different.

The earliest computer in the world is composed of a large number of components, and calculations are performed by the combination of components. So

Therefore, when performing different calculations, it is necessary to change the combination and wiring of components, which is of course very inconvenient.

Therefore, von Neumann proposed a new idea, which is to divide a computer into roughly five parts:

1. Input the number

Data and program input equipment;

2. Memory for storing programs and data;

3. A calculator that completes data processing;

4. The controller that controls the execution of the program;

5. The output device that outputs the processing result.

The computer we are using now,

Mobile phones are also a combination of these five parts.
