The current graphics card is divided into independent and integrated graphics, the production of independent graphics chips are mainly 2 manufacturers monopoly, NVIDIA and ATI, production integrated graphics chip has inter,nvidia,ati,sis and so on. Major graphics card manufacturers to use the graphics card chip provided by the GPU graphics card design and assembly .

At present all the memory of the particles are made abroad, mainly made in Korea. Domestic production is only PCB bo
Friends who often pay attention to three piece market changes will find that the current large capacity of memory is getting cheaper, which makes many users have the idea of upgrading memory. Looking at the current memory market, new to dig up the brand is really a lot, in the frequency of memory, now DDR266, DDR33 memory has slowly faded out of the market.

"Teacher Zhu's IoT lecture" study notes

The first two sections of the teacher said a word, I forgot to write up, today to fill.
SoCs are basically read-write control of peripherals through similar gpio, memory controllers, and so on.
There are also special, like the watchdog, there is no peripherals corresponding to it.
Okay, let's start with our theme for today, Icache.
So, what is Icache?
It is a kind of memory, although it currently touches several kinds o
is more complex and usually has a pin:CE: Chip selection signal, low level active.R/W: Read and write control signals.RAS: The line address is a pass-through signal that is usually connected to the high-level part of the address.CAS: A column address is a pass-through signal, usually a low part of the address.Address: A set of addresses lines.Data: A set of bidirectional signal lines for data transmission.(3) features of SDRAM:
SDRAM means synchronous dynamic random access memory. Synchronizati

English full name is "error Checking and Correcting", the corresponding Chinese name is called "Bug Check and correction", from which we can see that its main function is "to find and correct errors", It is more advanced than parity correction technology mainly because it can not only detect errors, but also to correct these errors, these errors after the computer can correctly perform the following tasks, to ensure the normal operation of the server. It's not a memory model. That is because it

Up to now, there is still no proper solution. You can add a 4 K resolution video to an existing Blu-ray standard without compromising its compatibility. Although it is not necessary to improve the CD manufacturing process to update the h.265 standard, it is necessary to create a new player to play the new Blu-ray disc. Although some players ca

Install it to: C:/mingw. You 'd better download the automatic installation version to mingw.
2. Install msys to the mingw home page to download the latest version of msys: URL: http://www.mingw.org/download.shtmlIn the download list, current-msys is the msys Installer. Download its binary version (BIN) and install it under C:/msys/1.0. Specify the mingw position in the middle.
3. Modify the msys configuration fileModify/etc/profile (the Windows path is C:/msys/1.0/etc/profile)

7. Long Commands
When you write a long command in the AIX shell, you can use "\" as the line break tag. In this case, shell uses a ">" as the prompt.
8. variables in the Shell Environment
Variables can be defined in the shell environment for systems, users, shell programs and various applications. Variables can be defined by the system or by the user. You can also modify or delete the variables that have been defined by the system.
Example: HOME -- user's ho

There is also a variety of game hosts, such as PS2/PS2/gamecube/Wii, which are all variants of the standard ibm pc, designed for better computing and graphics capabilities. However, these buddies are not mixed up recently, because the iPhone has come out, and the computing and graphics capabilities of ordinary PCs are getting stronger and stronger. programmers who write games cannot use so many hardware resources at all, no more dedicated game host design is require
