Hello,everyone

2

00:00:01,433 --> 00:00:06,700

Today let's learn about Intle's 4th and 5th generation low-power CPU architecture

3

00:00:07,633 --> 00:00:14,166

This is the Intle 4th and 5th generation low-power CPU architecture diagram of the notebook motherboard

4

00:00:14,366 --> 00:00:19,233

The middle part is called CPU, the real thing is as shown on the right

5

00:00:19,633 --> 00:00:25,666

The eDP (Embedded DisplayPort) here refers to the display signal output by the CPU and sent to the screen

6

00:00:26,100 --> 00:00:30,433

This DP (DisplayPort) refers to the DP display signal output by the CPU

7

00:00:30,533 --> 00:00:33,533

For DP interface and CRT (Cathode Ray Tube) interface

8

00:00:34,233 --> 00:00:36,466

The middle refers to the conversion chip

9

00:00:36,633 --> 00:00:40,633

For example, convert DP signal to analog display signal

10

00:00:41,566 --> 00:00:43,500

This is the LPC bus (Low pin count Bus)

11

00:00:43,966 --> 00:00:46,466

For communication between CPU and EC

12

00:00:46,666 --> 00:00:49,200

EC manages keyboard, touchpad

13

00:00:49,733 --> 00:00:52,633

EC is also connected to SPI Flash (EC's program)

14

00:00:53,000 --> 00:00:57,000

CPU also manages the card reader through the PCIE bus

15

00:00:57,733 --> 00:01:00,466

Also connected to the MINI PCIE slot

16

00:01:01,100 --> 00:01:03,033

which is the wireless card slot

17

00:01:03,566 --> 00:01:06,166

It also manages wired network cards

18

00:01:06,633 --> 00:01:09,933

This "RJ45" refers to the network cable interface

19

00:01:09,933 --> 00:01:12,033

This is the network card chip

20

00:01:16,633 --> 00:01:22,533

CPU manages the accelerometer and temperature control circuit through the SMBUS (system management bus)

21

00:01:23,333 --> 00:01:26,000

And NFC (Near Field Communication) communication

22

00:01:26,200 --> 00:01:29,933

The SATA bus of CPU is connected to the hard disk

23

00:01:30,166 --> 00:01:31,666

and mSATA modules

24

00:01:31,900 --> 00:01:37,333

USB 3.0 device connected to the CPU's USB 3.0 bus

25

00:01:37,566 --> 00:01:43,200

The CPU's USB 2.0 bus is connected to many USB 2.0 devices

26

00:01:43,500 --> 00:01:46,633

For example, the USB 2.0 interface

27

00:01:47,966 --> 00:01:48,766

Bluetooth

28

00:01:49,633 --> 00:01:50,733

fingerprint

29

00:01:51,233 --> 00:01:52,600

camera and so on

30

00:01:53,800 --> 00:01:55,966

Also goes to the wireless card slot

31

00:01:56,200 --> 00:01:59,566

The sound card bus of CPU manages the sound card chip

32

00:01:59,933 --> 00:02:02,966

CPU also manages memory through the memory bus

33

00:02:03,533 --> 00:02:07,100

The memory used here are DDR3, DDR3L

34

00:02:07,133 --> 00:02:11,466

These are the architecture of the 4th and 5th generation low-power CPUs
