in addition, Kirin 810 continues the excellent communication ability of flagship chip, supports al cards and al volte, and realizes stable and fast mobile communication connection in various complex communication scenarios. At the same time, Kirin 810 launched a self-developed intermediate operator format, which greatly enhanced the compatibility of Huawei hIaI and accelerated the implementation of more AI applications
3. The utf-16 version that encodes different a's occupies one byte of English and two bytes of Chinese characters in memory. The utf-16 version has two bytes of English and two bytes of Chinese characters. The UTF-32 version has four bytes of English and four bytes of Chinese characters. The utf-16 version does not exist. It is better to apply to different situations

Qilin 990 is better than Xiaolong 855 plus
{rrrrrrr}
extended data
Qilin 9905g outperforms snapdragon 855 + in performance and energy consumption. Even some indicators have left snapdragon 855 + behind. Of course, this has a lot to do with the more advanced 7Nm + EUV process
in addition, Qilin 990 5g has integrated 5g baseband that snapdragon 855 + does not have. In the 5g era today, Kirin 990 5g is the best choice for users to experience 5g. For users who love taking photos, the mate 30 series with Kirin 990 5g is obviously a better choice

6. In the driver of sound card, one is OSS (open sound system) and the other is alsa (Advanced Linux sound Architecture). OSS is a commercial sound card driver, you need to pay for it. Generally, we are using the sound architecture of alsa
Advanced Linux sound architecture is abbreviated as alsa, which translated into Chinese means advanced sound architecture of Linux. Alsa not only includes the support and driver of sound card< Its features are as follows:
1. Efficient support for all audio interfaces, from ordinary user's sound card to professional level multi-channel audio equipment
2. The sound card driver is completely molar< 3. SMP and thread safe design.
4. The development library (alsa LIB) provides a simple and convenient way for program design, and has advanced effects and functions
5. Support the old version of OSS API interface, which can provide compatibility for most OSS applications; OSS is a commercial driver. A simplified version of OSS code has been moved into the kernel and alsa, among which alsa OSS is; It is said that OSS does not exist at present; We don't need to use the commercial version provided by OSS company; It is enough to use alsa and OSS
how to view hardware chip
in Linux operating system, all hardware is distinguished by chipset, and brand is not the most important; The most important identification of hardware is chipset; So when you ask for help in the discussion area, you only say the hardware brand, but do not provide chipsets. We can't help you, remember
when we look at the chipset of the hardware, the command is lspci - V or dmesg, because the output information of dmesg is not too much, it is not intuitive; So lspci - V is often used; It can also be obtained by lshal; The most convenient is lspci - V; It is better for beginners to use lspci - V
code:
[ root@localhost Beinan] # lspci - V
after we run lspci - V, if we look at the sound card chipset, we will send the following paragraph< br />[ root@localhost beinan]# lspci -v
Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M)
AC' 97 Audio Controller (rev 03)
Subsystem: Hewlett-Packard Company: Unknown device 3080
2.6.11-1.1369_ FC4 i686 i686 i386
the above shows the kernel version and processor architecture of the system; Lsmod view the loaded kernel mole
If a device is loaded as a mole ring kernel compilation, it is mainly viewed through lsmod< br />[ root@localhost Beinan] # lsmod
maybe the buddies of Linux will ask, where is the kernel's mole? Can we manually load the mole; For example, in Fedora 4.0, we can see the following:
[ root@localhost beinan]# ls /lib/moles/2.6.11-1.1369_ FC4 / kernel /
arch / crypto / Drivers / FS / lib / net / sound / where sound is the storage directory of the sound card mole, most of the hardware drivers are in the drivers directory, and FS is the directory of the file system mole; Net is the storage directory related to network, such as some moles supported by network protocol and firewall; Arch is about CPU...
if we want to load moles by ourselves, we can check the information of corresponding moles in these directories, and then use modprobe to load them< br />[ root@localhost Beinan] # modinfo snd-intel8x0
to view the information of a mole, we use modinfo to view it, and the mole we want to view should not bring. Ko or. O and so on; For example, you can view information similar to the following< br />description: Intel 82801AA,82901AB,i810,i820,i830,i840,i845,MX440; SiS 7012; Ali 5455
through this, we can know that this is Intel integrated sound card. The sound card information obtained through lspci-v feels that they are very similar; So we can try to use this mole to drive< br />[ root@localhost Beinan] # modprobe snd-intel8x0
load the mole with modprobe, and then we can see it through lsmod; The sound card mole is loaded in this way, so is the driver mole of other devices.

7. Based on 3518a and 3518c, hi3518e is developed. As a new generation of IP civil camera SOC, hi3518e integrates a new generation of ISP, optimizes the image processing algorithm before encoding, and adopts a new generation of H.264 encoder. At the same time, it adopts instry-leading low-power technology and internal low-power architecture design, which makes hi3518e continue to lead the instry in low bit rate, high image quality and low power consumption. Hi3518e integrates DRAM, por, RTC, audiocodec, sensor level conversion and various clock outputs, which will greatly rece the EBOM cost of IP cameras. Similar to Hisilicon DVR / NVR chip, the SDK design can support the rapid mass proction of customers' procts and realize the system layout of DVR / NVR and IP cameras
the design of hi3518e embedded DDR can further rece the proction cost and development cycle of solution providers and manufacturers. It is especially suitable for the price sensitive and "short, flat and fast" characteristics of the consumer market, and will become a "sharp weapon" for manufacturers to seize the civil market<
hi3518e is implanted into danale IOT cloud platform service, which further reces the secondary development workload of manufacturers, improves the plug and play function of IPC cameras, and provides IOS, Android, PC and other client software. The software includes basic functions such as P2P viewing, alarm push and other value-added services such as cloud storage, cloud push, cloud watch and cloud sharing. In addition, Dana can provide services including user management interface, standard API and client, personalized customization, etc., which can save the cost of self built platform, deployment and maintenance of server, renting IDC service, paying license fee, etc., and greatly shorten the technology development cycle.
