Mobile phone camera Basics Http://blog.csdn.net/qikaibinglan/article/details/5882821 As a new mobile phone shooting function, the built-in digital camera function is the same as the low-end (0.1 million-1.3 million pixels) digital camera we usually see. Compared with traditional cameras, traditional cameras use "film" as their carrier to record information. The "film" of digital cameras is their imaging and photosensitive device, which is the heart of digital photography. The sensor is the core

performance Computing. At present, the mainstream PowerPC processor manufacturers have IBM, Freescale™semiconductor (formerly Motorola Semiconductor Division), AMCC, LSI and so on. One of the most popular PowerPC processors is IBM and Freescale. This article on the two companies based on the PowerPC processor, started to tell the PowerPC family. IBM's PowerPC family IBM currently has a total of 3 major P

product of EEPROM. Its biggest feature is that it must be erased by block (the size of each block is not fixed, and products of different manufacturers have different specifications ), the EEPROM can only erase one byte at a time ). Currently, "Flash Memory" is widely used on the motherboard of a PC to save BIOS programs and facilitate program upgrade. Another major application area of Ram is used as a replacement for hard disks. It has the advantages of earthquake resistance, fast speed, no no

science, Alan. On this day, at the "2014 Turing Test" conference held by the Royal Society, the chat program "Yukin Gustmann" (Eugene Goostman) First "passed" the Turing test. Von Neumann architecture: The computer should use binary; the computer should have as large a memory as possible to store program code and data; Directives should be stored sequentially in memory and addressed by program counters, but should also allow for conditional transfers, a design thought called stored-pro

Five years ago, one of almost every 10 TV ads was bound to be a mobile phone advertisement. in that era, mobile phone advertisements were unprecedentedly prosperous. According to CCTV statistics, at that time, mobile phone advertisements ranked first among the three categories in terms of revenue and quantity. Five years later, it may be a luxury for the audience to see mobile phone advertisements on TV. The reason for this is the new changes in the mobile phone industry chain with the arrival o

accordance with the contents of the BIOS. To be precise, the BIOS is an interface between the hardware and the software program or a converter, which is responsible for the immediate requirements of the hardware and executes the hardware requirements according to the software. Computer users in the process of using the computer, will be exposed to the BIOS, it plays a very important role in the computer system. What is CMOS? CMOS, namely: complementary Metal Oxide

, optimized architecture, power management mode, ultra-low power peripherals, energy-saving USB functions, and exclusive ultra-low power manufacturing process. Stm32l0 reduces the power consumption in the running mode to 87 μA/MHz. When all Ram data is retained, the power consumption in the stopped mode is set to ipvna, and a low-power timer is integrated to quickly wake up 3.5 μs, this allows Application designers to make full use of different low-power modes. With the megal0 series, designers

features of stable wavelength, adjustable and high speed and low chirp of the modulator. There are several integrated light sources: One is the DFB semiconductor laser and the electronic absorption modulator monolithic integration. The second is the single chip integration of the DFB semiconductor lasers and the m-z modulator: There are also distributed Bragg reflector (DBR) lasers and modulator monolithic

less than the Vosa and vosb change time, it can be considered that v osa and vosb remain unchanged during ts time, and the following can be obtained: The AD855X series adopts the optimal design, that is, AA = AB, BA = BB> 1. Therefore, the above formula can be reduced: As can be seen from formula (11), the AD855X series amplifier has a signal magnification of aaab, while the inherent offset of the amplifier (Vosa + vosb) is only AA. It can be seen that the use of a d855x series amplifi
