The first embedded processor Xingguang intelligent No.1 independently developed in China was born
China’s first embedded neural network processor (NPU) was born after more than five years of efforts. It was successfully applied to embedded video monitoring chips for the first time in the world and achieved mass production on March 6 this year. Zhang Yundong, executive director of the State Key Laboratory of “digital multimedia chip technology”, […]
Technical comparison between analog and digital cameras
The analog camera adopts interlaced scanning. When a picture is composed of odd field and even field pictures at different times, the moving objects in the picture are prone to generate sawtooth, flicker and other adverse reactions. In order to eliminate sawtooth, it is necessary to do software anti staggered image processing, which will also […]
Ultra low power standby solution based on MSP430
There are many kinds of electronic devices, such as computers, televisions, mobile phones and even wearable devices. These products have a lot of energy loss in the use process, and some power consumption in the case of standby. The number of electrical products used in private homes and offices is growing at an extremely rapid […]
Intel multiple test models processor exposure
Advanced manufacturing technology used to be Intel’s most powerful weapon, but didn’t want to stumble on 10nm. There is only one ice lake in the mass production of consumer products, and only the low-power sequence of the light and thin platform. In fact, ice lake was originally the second generation of 10nm process product planned […]
What new experience will flash bring
The future development of NAND flash memory involves more layers and bits per storage unit. At the same time, nvme of, memory like memory and other new technologies will fundamentally change the application and development of memory and memory. It is never easy to predict the future development of any technology, so is memory technology. […]
Using ARM microprocessor and ZigBee module to realize the design of wireless serial port hub
1. Introduction With the continuous progress of science and technology in the 21st century, wireless and mobile communication have been developed rapidly. New concepts and products, such as convenient wireless access and wireless interconnection, have been gradually integrated into people’s work and daily life. Nowadays, due to the large use of wireless frequency, the wireless […]
How to keep low temperature in high and low temperature test chamber
The analysis of the refrigeration failure of the high and low temperature test chamber with low temperature can not be maintained. First, observe whether the high and low temperature chamber refrigeration compressor can be started in the operation process of the high and low temperature test chamber. If the high and low temperature compressor can […]
Application analysis of bidirectional RS232-RS485 converter in TV monitoring system
In the TV monitoring system, in order to collect the information of each information point (video, audio, alarm signal) and control the front-end equipment (PTZ, lens, shield, light, etc.), we need to lay a large number of cables. These cables are mainly wired in two ways: star connection and T-connection. Star connection is the most […]
