Hello everyone, today let's learn about the bus between CPU and memory

2

00:00:05,866 --> 00:00:09,166

This bus is also what we often call the memory bus

3

00:00:09,900 --> 00:00:17,166

The communication bus between CPU and memory includes data line, address line and control line

4

00:00:17,666 --> 00:00:22,100

We can look at the data cable on the memory slot through the memory slot

5

00:00:22,733 --> 00:00:28,833

From DQ0 to DQ63, there are a total of 64 data lines

6

00:00:29,166 --> 00:00:30,400

Here are 64

7

00:00:30,666 --> 00:00:37,333

Its address lines are from A0 to A15 here, a total of 16 address lines

8

00:00:38,000 --> 00:00:45,866

The rest is the control signal line, and its power supply, clock, reset and other signals

9

00:00:46,733 --> 00:00:50,066

There is a memory controller inside the CPU

10

00:00:50,566 --> 00:00:54,300

Dedicated to managing memory, and memory communication

11

00:00:54,800 --> 00:01:01,833

All data information and address information between CPU and memory are transmitted through these data address lines

12

00:01:02,333 --> 00:01:04,666

OK, this is the memory bus
