At the international test conference, Gadi Singer, vice president and vice general manager of Intel, pointed out in his speech entitled "Meeting the challenges of spectrum nanotechnology and gigabit complexity" that since 1940, the number of MIPS per cubic foot or per pound has increased 100 times every 10 years. Although it has been changing exponentially on the smooth curve, there are still many discontinuities and deformation points at that time. "At present, four different trends are extending the curve in all directions," Singer said. First of all, IC complexity and diversity are being affected by [Detailed]

Without constructive opinions on the future workforce, our fear of AI may become a self fulfilling prophecy. Our obsession with AI is not difficult to understand: over the years, from Elon Musk and Mark Benioff to Bill Gates, many of the most famous entrepreneurs in Silicon Valley have warned about the upcoming automation wave, saying that they may threaten our work and lifestyle. At the World Economic Forum held in Davos this year, Jack Ma, the founder of Alibaba, reiterated his prediction that AI and robots will not only occupy a large number of jobs, but also launch the third world [Detailed]

Principle: The key to this project is, FSK is continuous phase, and the frequency of high level and low potential is not a multiple (1200Hz and 2200Hz). It is difficult to determine the rising edge and falling edge by measuring the pulse width. Theoretically, the rising edge and falling edge can be determined by checking the time table with the amplitude after A D conversion, but the software and hardware are too complex, so it is better to buy a finished product of fsk to demodulate IC. My method is to measure the pulse width, Because the data is asynchronous serial communication, the clock is determined by the falling edge from 1 to 0, that is, the clock is determined by the change from 1200hz to 2200hz. The key is 12 [Detailed]

With the development and progress of the automobile industry, people put forward higher requirements for the power, economy, safety and emissions of automobiles. The traditional mechanical control system has been far from meeting these needs. Electronic control system has gradually replaced mechanical control system with its characteristics of high precision, high speed, flexible control, stability and reliability, which is the development trend of automobile control system. As the requirements for control performance become more and more strict, the requirements of automotive electronic control system on the controller become higher and higher. The development and design of the controller generally go through the steps shown in Figure 1, that is, from the top to the bottom [Detailed]

Although the fingerprint identification application was first adopted by Apple's iPhone, the flagship phones of other camps also quickly caught up, but the middle and low level phones have not caught up because of cost considerations. However, the mobile payment trend has been achieved, and the quotation of fingerprint identification module has also rapidly slipped. Brand mobile phone manufacturers in mainland China intend to comprehensively add fingerprint identification functions. IC design companies across the Straits forecast that the shipment of fingerprint identification chips in the third quarter will be expected to double compared with the first half of the year, and the annual growth rate of shipment in 2017 will reach more than 100%. Although foreign investors still occupy half of the global fingerprint identification chip market [Detailed]

DC-DC circuit principle: DC-DC is the abbreviation of DC to DC in English, so DC-DC circuit is a circuit that converts a DC power supply into different voltage values. DC-DC is a branch of switching power technology, which includes AC-DC and DC-DC. DC-DC circuit is divided into: Boost converter: circuit that converts low voltage to high voltage. Step down converter: circuit that converts high voltage to low voltage. Inverter: circuit that changes voltage polarity, including positive power supply to negative power supply and negative power supply to positive power supply. ... [Detailed]

The landing of new projects gave Li Weiqiang some hope. "Fifteen wall mounted AC charging piles and three vertical AC charging piles are relatively large orders". After more than two years of entrepreneurship, the general manager of Beijing Blue Ocean Xinghua Technology Development Co., Ltd. talked about the charging pile industry and repeated several times that "business is not easy to do". Li Weiqiang's feelings are quite representative in the industry. In the past two years, China's new energy vehicles have ushered in explosive development. A large number of people and capital have poured into the field of charging piles, and the market has experienced phased overcapacity. The industry even said jokingly, "The speed of selling cars can't catch up with the speed of piling..." [Detailed]

Today, when the scale of bridges is getting larger and larger and bridge damage accidents occur frequently, it is very urgent and necessary to establish a durable and reliable structural health monitoring and safety monitoring and early warning system for important long-span bridges. However, because the bridge structure is directly exposed to traffic noise, dust, extreme temperature, marine corrosive climate and other harsh environments, the structural health monitoring and early warning system is required to be stable, reliable, durable and anti-interference. By distributing NIPXI chassis and signal conditioning and acquisition modules at appropriate distances in different positions of the bridge structure, stable and reliable acquisition of various types of sensor signals nearby can be completed. Each [Detailed]

As shown in the figure, it is a single-phase quantitative power supply control circuit. The circuit consists of load detection circuit, electronic switch, monostable timing circuit, relay control circuit, etc. The load detection circuit is composed of transformer B and D1, C1, W1 to detect the load of the circuit. The electronic switch consists of BG1, DW1 and R1, which are controlled by the detection signal. The timing time of the monostable timing circuit composed of IC (555), R3, C4, etc. is td=1.1R3C4, and the time corresponding to the parameters in the figure is about 4 minutes. When the power consumption exceeds the load, the voltage stabilizer tube DW1 breaks down, and BG1 is saturated [Detailed]
