Clock part(1) clock domains5pv210 there are altogether three clock domains: Msys,dsys,psysMSYS: (main system) master clock domain, including cpu,ddr memory, Irom and Iram, etc.Dsys: (display system) shows the clock domain, which is generally related to video in this clock domain, such as hdmi,tvenc ...PSYS: (peripheral system) Peripheral clock domain, is the Gpio interface, I²C interface, UART interface, and so on these peripheral devices on this clock domain.Each clock domain is connected by a

When comparing and selecting a crystal, the designer should consider the following 10 key parameters.1, the frequency range of the operating frequency crystal oscillator is generally between 1 and 70MHz. But there are also special low-frequency crystals such as the universal 32.768kHz clock crystals. The physical thickness of the crystal limits its frequency limit. Thanks to the development of manufacturing technologies such as reverse countertops (inverted mesa), the frequency limit for crystal

storage of a second sampling rate of 44.1KHz, sampling size of 16bit, two-channel PCM encoded audio signal, the need for 176.4KB of space, 1 minutes is about 10.34M, which is unacceptable to most users, especially like listening to music on the computer friends, to reduce disk occupancy, only 2 ways to reduce the sampling Indicator or compression. Reducing the indicators is undesirable, so experts have developed a variety of compression schemes. Due to the different use and target market, vario

I wrote a topcoder exercise question a few days ago. +Code+ CommentsArticleNow, I will write the second article in this series.Note: There will be three articles in this series, a complete set of SRM questions I have done before, with 250, 500, and 1000 points, this article will introduce the 500 points. afterwards, I will occasionally take the time to participate in the latest SRM, and then offer the questions and answers to them :) Source: srm250 div2Level: 500 pointsQuestion:Problem Statemen

increase the harmonic component and the so-called side band frequency component. What is the frequency of the Side Band? How is it produced? There are two frequencies W1 and W2 in the rotating machine. Under these two frequencies, the response of the mechanical vibration shows a periodic pulse, that is, to present the signal whose amplitude is modulated by a difference frequency (W2-W1) with W2> W1) to

energy storage capacitor used as an IC can provide and absorb the charge and discharge capabilities instantly when the IC is opened and closed. In practical applications, the typical 0.1uf decoupling capacitor in digital circuits has a distribution inductance of 5 NH, the parallel resonance frequency is about 7 MHz (only the noise at this frequency has a better decoupling effect ). The capacitance of 1 UF and 10 UF is equal to the parallel resonance frequency above 20 MHz, which is better to re

or 1.7 m/MS (for comparison: 1000 km/h jet aircraft speed in combination with 0.27 m/MS ). When the Sample Set spans a large amount of time, the signal phase and frequency change. The actual system may not change the data collection rate for each star, but may only change the local coherent code sample (some documents refer to as the copy code ). The Calculation of moving correlation using different micro-bias frequencies before and after a sample se

Secondly, this is a very charming female photo, and it is not surprising that the image processing field (most male) is willing to use an image that they think is attractive ." This picture contains a wide range of frequencies, including smooth skin at low frequencies and feathers at high

worth the candle. Therefore, we can only compress the original file with a "natural, not random phrase-type repetition tendency ".2. encoding compression uses the tendency of different frequencies for each single byte to change the fixed-length encoding to an uncertain-Length Encoding. The encoding is shorter for high-frequency bytes and longer for low-frequency bytes, compression Effect. If the "result" of compression in bytes is taken as one byte b

of the power supply or the quality of the power supply is of critical significance to the entire system's anti-interference ability. Power integrity is actually part of signal integrity, but is listed here separately considering the importance of power to all systems. It should be declared that in the actual system, it is not easy to achieve this, there will always be various frequencies of noise in the system. In circuit design and PCB layout, the s

" frequencies based on the signal strength. China Telecom has two types of mobile phone network icons: "1x, 3G ". 1x: it is called CDMA 1X and belongs to a 2G network. This is an early CDMA wireless network transmission mode. The theoretical peak transmission rate can reach 153.6 kbps (19.2 K/s ). 3G: All called CDMA2000 is a 3G network and is a data transmission mode based on the evdo standard. This is a mainstream wireless network transmission mode.

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The external frequency of the CPU is the baseline frequency of the CPU and even the entire computer s

no obvious periodicity. When a voiced sound is sent, the air flow generates a relaxation vibration through the gloal cords, resulting in a quasi-cycle excitation pulse string. The pitch frequency is called the pitch frequency. Generally, the pitch frequency is related to the length, thickness, toughness, strength, and pronunciation habits of the individual vocal cords, and reflects the personal characteristics to a large extent. In addition, the pitch frequency varies with gender and age. Gener

frequency of the input signal, the original signal can be reconstructed from the sampling signal series. The normal human hearing frequency ranges from 20Hz ~ Between 20 kHz, according to The nequest sampling theory, in order to ensure sound distortion, the sampling frequency should be around 40 kHz. Common audio sampling frequencies include 8 kHz, 11.025 kHz, 22.05 kHz, 16 kHz, 37.8 kHz, 44.1 kHz, and 48 kHz, it can also achieve the sound quality of

line and radiation (EMI ). To eliminate unnecessary signal energy, use a chip magnetic bead to act as a high-frequency resistor (the attenuation). The device allows the DC signal to pass through and filter out the AC signal. Generally, the high-frequency signal is above 30 MHz. However, the low-frequency signal is also affected by the chip magnetic beads. Magnetic Beads have high resistivity and magnetic permeability, which is equivalent to a series of resistance and inductance, but the resista

electrical characteristics of the transmission media, generally, different transmission media have different processing capabilities for signals in different frequency segments. The ethernet cable processes the baseband signal, and the wide area network light emits high-frequency modulation signals. Mobile Communication, 2G and 3G require different carrier frequencies. Can these media (air, wire, optical fiber, etc.) input at a certain frequency be b

Fault 3: Fake level Two cache Symptom: My computer has 256k cache, but obviously no other 256K cache motherboard fast, CMOS L2 cache behind is enabled. Analysis and resolution: the use of speed-measuring software compared to allow and prohibit the cache of two states, found that the computer speed has not changed. This indicates that the motherboard's cache is fake. Becaus
