I. The concept of PWM and duty-free ratio ①PWM: Also known as pulse width modulation technology, is an analog control mode, the PWM waveform as shown below. ② duty cycle: refers to the proportion of the high level in a period. For example, a duty cycle of 50% means that the high level accounts for half of the period. Two, PWM fixed frequency speed regulation principle In the PWM speed regulation syste

How to improve PHP running speed? To improve the speed of PHP operation? One of the biggest advantages of using PHP is that it's fast. In general, PHP always has enough speed to support the dynamic generation of Web content, and many times it is not even possible to find a faster method. However, when faced with massive traffic, high-load applications, limited b

(1) thoughts on improving database insertion Performance: Try to write Data to the Data File at a time and reduce the checkpoint operation of the database. The following four configuration items are modified:1) set the innodb_flush_log_at_trx_commit configuration to 0, and set it to 0 based on past experience, which greatly improves the insertion speed.0: Write the log buffer to the log file and flush the log file every second, but do nothing at trans

Due to abnormal project requirements, database records need to be rapidly increased in a relatively short period of time (due to the increase of 0 to 0.4 billion in two or three days ). The optimization process is very difficult throughout the process.

1GHZ=1000MHZ1MHZ=1000KHZ1KHZ=1000HZ calculates the time unit of the pulse signal period and the corresponding conversion relationship is: s (seconds), MS (MS), μs (microseconds), NS (nanosecond). Among them: 1s=1000ms,1ms=1000μs,1μs=1000ns. P42.4ghz, refers to the CPU's main frequency. The CPU clock frequency (cpuclockspeed) of the CPU core. What is commonly referred to as a CPU is how many MHz, and this number of MHz is "CPU frequency." Many people think that the CPU clock is the

With USB3.0 control chip motherboard, although has become the mainstream of the market, but for most users still use USB2.0, USB2.0 file transfer speed also seems to be unable to meet their requirements. In fact, now USB2.0 speed there is room for improvement, we can use the speed-increasing patch to explore the potential of USB2.0. USB 2.0 Why not reach the 60m

1. Use embedded HTMLCodeInstead of the PHP echo statement. Because PHP is an embedded web Programming Language To embed HTML code and PHP code into each other.

What is the difference between stack and stack? Why is stack speed fast and stack speed slow? Both stacks and stacks are places where Java is used to store data in Ram. Unlike C ++, Java automatically manages stacks and stacks, and programmers cannot directly set stacks or stacks. The Java heap is a runtime data zone and class (the object allocates space from it. These objects are created using commands suc
