No matter which processor you are learning, the first thing you need to understand is the registers and working mode of the processor. ARM has 37 registers, including 31 general registers and ...[Details]

Introduction Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]

1. Disadvantages of choosing too high a voltage level Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]

With concerns about the growing energy crisis, motor efficiency has become an important and timely topic. This is because motors use 63% to 70% of the electricity produced in the United States and ...[Details]

The most important components of new energy electric vehicles are power batteries, electric motors and energy conversion control systems. The power battery must achieve high performance such as fas...[Details]

Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]

High specific energy lithium/thionyl chloride (Li/SOCl2) batteries are widely used in multi-functional intelligent meters (such as smart meters, water meters, etc.) as real-time clocks and memory b...[Details]

1. Sensor According to the national standard GB7665-87, a sensor is defined as a device that can sense the specified measured quantity and convert it into a usable output signal according to a...[Details]

This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]

UPS is an uninterruptible power supply (UPS). This device can ensure that after a power outage in the computer system, users can continue to work for a period of time and save files urgently, witho...[Details]

The construction of voltage and current feedback amplifier application circuits is generally the same, except for a few key points. Current feedback amplifiers have higher sl...[Details]

Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]

In the field of video surveillance, video compression encoding formats have evolved from M-JPEG, H.263, MPEG4 to H.264. Currently, H.264 is the mainstream compression algorithm. Its biggest advantage ...[Details]

“Productivity determines production relations, and the development of productivity determines the change of production relations”, yes, society is always full of changes, and advanced science and t...[Details]

In recent years, the rapid development of high-performance digital signal processing chip DSP (Digital Signal Process) technology has made it possible to realize real-time speech recognition. Amo...[Details]
