IntroductionThe AXI protocol is probably a protocol that we often encounter in our usual circuit design, and it's a good deal, and we'll be familiar with this section.At first glance, the AXI protocol signals are numerous, dazzling and easy to Fameng. But in fact its basic idea is very simple. Just grasp the following points:1,valid/ready protocolThe Axi protocol is a typical bus protocol based on the Valid

capacitor is usually large.By the way, it is pointed out that the charge and discharge time constants of the filter capacitors of the switching power supply are usually large, dozens of times the Switching Power Supply frequency period, or even hundreds of times. Therefore, the energy storage filter capacitor can be charged according to the sine curve or discharge according to the exponential law. We can regard it as charging and discharging according to the linear (straight line) law. This is

In a digital system, a clock pulse of multiple frequencies is often required as the driving source, which requires the frequency of the FPGA's system clock (too high) to be divided. The frequency divider is divided into odd frequency, even frequency, half-integer and fractional, in the FPGA system where the clock is not very strict, the frequency divider is usually realized by the counter loop. Even divide: Assuming n-frequency, by the clock to be divided by the counter count, when the counter f

Minimum system board Design(1) using AMS1117 to achieve 5V voltage stability of 3.3VThe AMS1117 series of regulators are available in adjustable versions with a wide range of fixed voltage versions designed to provide 1A output current and operate with a low dropout voltage of up to 1V. At maximum output current, the dropout voltage of the AMS1117 device is guaranteed to be

1. Power supply is the lifeblood of the system and cost-saving. This is very beneficial to product stability and passing various certifications.1. Try to use the fill filter to increase the 104 H inductance. Each chip power supply pin must be connected to a bypass capacitor;2. Use a Varistor or transient diode to suppress the surge;3. Separated by mode and digital power, large current and small current circuits are separated by magnetic beads or zero euro resistance;4. The

mentor and Cadence is as ugly as it is. Especially that line. It's really not easy to draw a line that doesn't bend. Later, because of the relationship between a project and learn the mentor company software, give me the most impressive is the mouse gesture recognition, other because of the basis of CR-5000, learning is still very fast. Later I used cadence, orcad, some work needs, some self-taught, and not very deep. The general feeling is that no matter what the software is, it is only a too

For Java programmers, mastering object-oriented design theory and some design patterns is an essential skill. To start programming without learning a theory is similar to learning a language without studying the alphabet. There's a lot of object-oriented theory, design patterns and best practices on the market, but only a few

will be significantly increased, this is the piezoelectric resonance, similar to what we often see LC loop resonance. due to the importance of crystal oscillator in digital circuits, we need to handle it carefully when using and designing: 1. Crystal Internal quartz crystal, by external impact or fall prone to damage to quartz crystals, resulting in crystal vibration does not start, so in the design of the cir
