EmbeddedLinux Bare Metal Development (12)--inand Introduction First,Inand Introduction in and is a memory chip developed by SanDisk company, which can be considered as an SD card or MMC card chip. Inand is the SanDisk company complies with the EMMC protocol chip family name, the internal use of MLC storage particles. The Inand interface circuit is designed to be complex and fully functional, providing a

First it is specifically for Datafab company's products, and second, although CompactFlash reader is a flash device, but obviously not a U disk. Because the code in the Drivers/usb/storage directory is for a device such as the USB mass storage, not for a particular device. The USB flash drive is just one of the mass storage devices. Another example:101 Config Usb_storage_sddr55102 bool "
Microsoft, together with Intel, AMD, ATI and Nvidia, released the basic recommended configuration requirements for Windows Vista certified PCs. Many common hardware appears in the list, so users who buy computers in recent years can be reassured. The recommended configuration requirements are as follows (including but not limited to):
-MB memory
-Use any of the following Cpu:intel core Duo, Intel Core Solo, Intel Pentium M, Mobile Pentium 4 (no Hyper-Threading technology is available), Intel C
List of graphics cards supported by WINDOWS7 (the following are the minimum requirements. If your graphics card is antique than the following, please give up or wait for a third-party driver in the future)ATI GPUsDesktop:ATI Radeon? X1900 SeriesATI Radeon? X1800 SeriesATI Radeon?

But it also brings about some problems, such as restarting X-Window and slowing down, but it solves the problem that the lower right corner of the page is not normal for a long time. I will not comment on my personal wishes, only the installation steps are provided:
In addition, GNOME is recommended for the desktop environment. In my personal test, I think 3D is not very stable in the KDE environment.
1. Pure systems with no old drivers installed and the upgrade is complete.

relatively low compared with the independent graphics card and need to occupy the memory. Although the performance of the independent graphics card is strong, the heat and power consumption are relatively high, and the memory is not occupied.
Q2: What are the current independent graphics card models? What is the performance?
Answer: The mobility Radeon series of ATI: 9200, 9600, 9700 (9700se), x300, x600, and x700; NVIDIA geforce go series: 6200t

1. Storage media (Storage Medium), also known as storage media, stores the physical vectors of binary information.Main categories:1. Semiconductor Memory: A semiconductor circuit as a storage medium memory.Divided into random access memory (RAM) and read-only memory (ROM) by functionDivided into bipolar transistor memory and MOS transistor memory by manufacturing process2. Magnetic surface Memory: the magnetic material coated on the carrier surface has two different magnetization states represen
digital devices are the primary markets for flash. As mentioned above, the mobile phone industry is dominated by NOR flash memory, and Flash memory chips are directly deployed on internal circuit boards, however, digital cameras, MP3 players, handheld computers, and other devices require that the storage media be replaceable. Therefore, interface standards must be developed to achieve connection. The flash card technology came into being. A flash card uses flash memory as its core storage devic
Inand is a small, easy-to-integrate high-speed NAND Flash SD interface chip. Embedded flash memory is a popular storage solution for high-end consumer electronic products such as MP4 players, GPS communication devices, personal media players, and mobile phones. SanDisk inand is a complete sub-system that integrates a serial controller and high-speed nand flash memory on a single device. The inand controller saves the CPU and RAM buffer of the primary

For this type of devices, there are special documents and specDescribes the communication or physical power-on characteristics of such devices.Disks are only one of them. The communication protocol used by such devices is called bulk-only transport.Protocol. For example, for config_usb_storage_sddr55This option, kconfigThere i

"comparability." My humble opinion is that 1300 yuan, you can only buy about 500GB capacity of solid-state drives, but Seagate is 5TB, 10 times times the difference in capacity of the temptation to imagine.
From an ordinary consumer point of view, at a price of about 1000 yuan 1TB capacity WD Blue, for example, Sandisk nm TLC flash type, reading and writing aspects are in 500mb/s ability, as the main computer hard disk is indeed excellent, The inher
