How did the seniors deal with it?They used three different lines to transmit the data: address bus, control bus, data busWork in the following ways:5. Address Bus

1. Logical Address
Logical Address is the most vague concept.
The explanation in understanding the linux kernel is related to virtual addresses. Based on the concept of hardware MMU and Software Memory Management, you can refer to the second chapter of UTLK memory addressing, I have a very detailed explanation.
However, the

First, let's talk about the evolution of the bus. PC architecture series: the development history of CPU, ram, and Io bus.

The AHB is primarily used for connections between high-performance modules such as CPUs, DMA, and DSP, and acts as an on-chip system bus for the SOC, which includes the following features: Single clock edge operation, non-tri-state Implementation mode;Support burst transmission, support segmented transmission, support multiple host controllers, configurable 32-bit ~128-bit bus width, support byte, half-byte

Now we have many identities on the Internet. For example, I have three or four MSN accounts, QQ, GTalk, and web-based blogs and vblogs, in short, there are many. For small-sized mobile phones and MID-sized handheld devices, we cannot open N clients and N webpages like desktop. In fact, we don't care about the software we are using, we only want to find the contact. D-Bus provides the basis for IPC communication. Many mechanisms are built on D-

I just started technology after graduation, and now I am getting started, and I have been recognized by my colleagues and leaders. So I firmly believe that I don't need 10 years to achieve anything better than him. People are forced out. Only a firm belief will prompt us to grow and we will not be on the road to success.

By the way, record this blog: the Linux USB driver development of Mingyue may be available in the future.
The three important concepts of the Linux device model are bus, device, and driver. that is, bus, device, driver. In fact, the kernel also defines such data structures. They are struct bus_type, struct device, struct device_dr

In the process of application development, communication between objects is often handled. Generally, communication between objects is implemented through dependency and reference of objects or interfaces, which is normal, however, if there are many objects to communicate with each other, the reference relationships between objects may be the same as tho
