1. Overview
With the development of telecom technology and business, the competition in the telecom market is becoming increasingly fierce. In the fixed-line telephone market, mobile's distribution of fixed-line voice services is intensifying. In the broadband market, the dominant position of the value chain is gradually lost. In the wireless market, the growth of PHS is weak. These are a true portrayal of the severe challenges facing fixed network operators in China, and are also the main drivi
I. Huge Market Demands
Users' needs are the most basic driving force of FMC. With the emergence of a wide range of IP multimedia applications on the Internet, the majority of end users are no longer satisfied with the use of PC terminals to access the Internet, but want to use a multi-functional mobile terminal, no matter where to move, the access method, such as Cellular mobile Cellular system, Wi-Fi/WiMAX coverage, and indoor ADSL/Cable access, can
vc709e Enhanced Xilinx Vertex-7 FPGA V7 xc7vx690t PCIeX8 interface card based on FMC interface
first, the Board of Cards overviewBased on Xilinx's FPGA xc7vx690t-ffg1761i chip, the board supports FMC connectors with PCIeX8, 64bit DDR3 capacity 2GBYTE,HPC, Board supports a variety of interface inputs, and software supports Windows.second, functional and technical indicators:1, Standard PCI-E int
I have a piece of stm32f429 discovery Board, for some reason need to use 8080 interface lcd, and the block Development Board comes with the LCD interface using LTDC drive, so on the right atom here bought a 4.3 inch capacitive touch screen, driver IC for the NT35510.In order to quickly build a software engineering, I use the STM32CUBEMX tool to generate code templates, and write the LCD.C and nt35510.c two files, the code is as follows:Lcd.ctypedef struct _LCD_DRV{UINT32_T (*checkid) (void), voi
Due to the differences between the fixed network and mobile network in terms of access bandwidth, terminal authentication, and terminal mobility, how to view and solve these differences has become a key issue for IMS-based FMC.
The concept and architecture of IMS was initially proposed by 3GPP In R5. As a new domain in the third generation mobile communication, IMS provides multimedia services for users and achieves separation of business and control.
This article describes how to search for a geographical location in PHP and how to calculate the distance between two geographical locations. The example of a geographical location search uses the MongoDB database. For more information, see
Geographic location searchLBS stores the longitude and latitude coordinates of each location, searches for nearby locations, and establishes geographic location indexes
ObjectiveMost apps now have the ability to find nearby features, simply have to find the surrounding sports venues, complex with drops, and worship to find the vehicles around. This paper mainly describes the general implementation of locating nearby locations. Searching for nearby people is the same idea.Scenario ComparisonScenario 1 (performance is good)Database directly to the latitude and longitude, and then calculate the rectangle boundary value,

SkyDrive is a perfect cloud storage service combined with the system, and it is a service that Microsoft provides to the user conveniently. But in the windows8.1 built-in SkyDrive system default storage location, so that some users find it inconvenient to use, want to change a storage location. So what should we do to achieve our goal?

memory address, so the calling function is the memory address of the value has changed, so a point of the memory address in the value changed. Our print function prints the value in the memory address pointed to by a, not a itself, and a is still the same.Here's the code that implements the interchange of array elements, and we'll try to understand it ourselves: // 交换两个元素 private void exchange(int[] nums, int x, int y) { int temp = nums[x]; nums[x] = nums[y];
Why would they say shorter, not shortest? In the process of exploration, you can always find a shorter path, in this article, will tell the author of the exploration process of the rough description.The distance between the two locations, there are many in the natural environment, and in fact, the distance between the two positions is often preferred. But the problem is in the straight line, how to judge the path is a straight line it! In mathematics,
