25th Qualcomm held the 2018 Qualcomm China Technology and Cooperation summit in Beijing, announcing the 5G pilot program. Lenovo, OPPO, Vivo, Xiaomi, ZTE, Chantai technology at the summit said it will open cooperation and jointly accelerate the launch of the commercial top 5G terminal in 2019.The media rated this as "half of China's mobile phones for Qualcomm pla
The resources provided here are suitable for mobile phones with Qualcomm chip hvga and WVGA resolution.
1. How to view the mobile phone chipset

2. Enter the mobile phone model + GPU into Baidu Google
For example, if you enter the v880 GPU, you will soon find that the v880 uses adreno200 and then the adreno200 is Qualcomm GPU.

Small details: When we implement our own HAL Layer module and write an application to test whether the module is working properly, the following parameters should be written when compiling:

The following is an initialization process analysis of the MMC host Controller drive on the Qualcomm 8x50.
Analysis based on kernel version 2.6.29 (the main code is DRIVER/MMC/MSM_SDCC.C and msm_sdcc.h and Arch Code)
1. Types of buses involved in MMC
The code in the MMC directory mainly involves three kinds of buses, one is platform bus, the MMC host controller as a kind of platform device, it is need to register to the platform on.

the CPU instruction set, the instruction set is the most primitive prerequisite for the birth of a CPU, simply speaking, it is the command that instructs the CPU to do something and give it the order.For now, there are two companies that have the ability to develop mobile CPU instruction sets: ARM and Intel.ARM's ARMV5/ARMV6/ARMV7/ARMV8 instruction setCommon chip design vendors such as Apple, Samsung, Qualcomm, MTK, Nvidia, HiSilicon and other chip m
Qualcomm ultrasound 3D fingerprint scanner: Finger replacement password just around the day
Sound waves are not only applicable to sound, but also very suitable for accepting your fingerprints. Maybe one day it will replace the hard-to-remember password.
You can't even imagine recording your fingerprints.
At present, your secure fingerprint scan is only available when your skin is in good condition. The reader may not be able to accurately retrieve

Qualcomm msm8926 camera debugging notes, msm8926camera
Debugging a set of cameras on Qualcomm msm8926 a few days ago, ov5648 + imx135 was previously properly lit up, but a mini configuration version solution was needed in the future and must be compatible with ov2685 + ov8865, therefore, we should prepare for the preliminary debugging, and ask the camera module factory for the module spec and The datasheet
