, but Apple is not in the rest, not only in the product progress, but there is a decline in suspicion. In contrast to the two moves, Samsung can be described as "should be the trend and seek," and Apple is "riding, behind." From the consumer's point of view, the Galaxy A9 High Edition with the iphone SE, a six-inch large screen, a four-inch sketch, a different user experience. 　　 Galaxy A9 High Edition "fully armed", competitive advantage outstandingOf course, Samsung's competitors in China are

ASUS Low-priced mobile phone zenfone launched on the market topic, many people also on the use of the Intel Atom processor Zenfone, the deep fear that its compatibility problems can not be properly executed application app, what is this?Intel has been trying to move into mobile or tablet mobile markets in recent years, especially with the Android operating system (Forget Meego!). ), the tactic is to try to lower the power of the low Atom series of processors to meet the requirements of long-time

TP–Link and snake into the phone industryMany people are not unfamiliar with the Tp-link brand, because most of the routers used in the home are from this brand. Even the millet routers, polar routes and other new products, but still can not really shake tp-link in the Router Market Foundation. And its launch of the smartphone, perhaps you have not seen. In fact, as early as 2015 Tp-link on the creation of the independe

In February 2013, the next generation of 3DMark, in addition to the traditional Windows platform, added Android, iOS, and Windows RT three mobile platform versions to achieve Cross-platform test comparisons. 3DMark test Results The Android and iOS version 3DMark tested the graphics capabilities of the device through the Icestorm and Icestorm extreme two load scenarios, each with two pieces of animation to verify the graphics pro

In this year's domestic mobile phone, Huawei, Millet, OPPO, vivo performance eye-catching, including Oppo/vivo in the third quarter and even the reverse attack Huawei/millet, become the highest shipments of smartphone brands. Tall tree catches, now on the internet can often see a lot of people look down on oppo, Vivo, this is why? OPPO r9s In fact, the root of the contempt is: the OV manufacturers to avoid high price low match! Why these two brands of mobile phones, obviously

receiving devices at the same time. Currently, 802.11 communication is actually a point-to-point communication. If the same video stream needs to be sent to three clients, it needs three times times the bandwidth. With 802.11AC, bandwidth usage will be more efficient. the future of 802.11ac 802.11AC will become faster and quicker, as we mentioned earlier, the theoretical maximum of 802.11ac can reach 7Gbps. Although in real life and application will not really reach the theoretical maximum, but

information: Device utilization%-the total GPU time occupied by rendering. >95% means that the application is bound to the GPU. Renderer utilization%-the GPU time occupied by drawing pixels. Tile utilization%-the GPU time occupied by processing vertices. Split Count-the number of times the frame splits when the vertex data does not match the allocated buffer. PowerVR is a tiled-based delay renderer, so the GPU timing of each draw call cannot be obtained. However, you can use the Unity built-in

to obtain the corresponding Udevice device from the device chain list of Gpio Uclass and use its operation set Gpio Uclass links All Gpio udevice devices belonging to the Uclass provide a unified set of operation interfaces for the driver of Gpio Udevice Bank and Gpio on some platforms, some of the gpio using the same set of registers constitute a bank, for example, Samsung's s5pv210 of course, not all platforms have a bank concept, such as Qualcomm,

between electronic devices, exchanging data within 10 centimeters (3.9 inches).The technology evolved from contactless radio frequency identification (RFID), developed jointly by Philips Semiconductor (now NXP Semiconductors), Nokia and Sony, based on RFID and interconnect technology. Near Field communication is a short-range high frequency radio technology that operates at a distance of 20 centimeters at 13.56MHz. Its transmission speed has 106 kbit

bugs but lack global understanding. However, some content may be relatively simple for them. In addition, our statistics show that NFC and GPS have very few problems. According to the interview, it is also important to know about The datasheet of the NFC chip (GPS should be without such public information. However, this book does not consider NFC, GPS, and Wi-Fi HAL. On the one hand, I feel that the Wi-Fi driver layer is very closely integrated with the protocol. readers with a bit of research

Linear algebra4x4 Unit matrixThe 4*4 matrix represents 4 rows and 4 columns:Transpose of matrix: the new matrix obtained by replacing the line of matrix A with the column of the same ordinal is called a transpose matrix, which is called the transpose of the Matrix.Inverse matrix: Set A is an n-order matrix on a number of fields, if there is another n-order array B on the same number field, it makes: ab=ba=e. Then we call B a inverse matrix, and a is called a reversible matrix.Multiplication of m

Using RTOS programming, allocating the stack space for each task is a technical work: allocating more wasted system resources, less allocation, and I'm afraid a stack overflow will occur. Because of the presence of interrupts and preemptive schedulers, it is very difficult to estimate how many stacks a task requires, and today we present a way to get the remaining stack space for each task. This paper takes NXP lpc177x_8x series microcontrollers as an
