North Bridge Chip is responsible for contact memory, graphics and other data throughput of the largest components, and the South-South chip connection. CPU is through the front-end bus (FSB) to connect to the North Bridge chip, and then through the Bei Qiao chip and memory, graphics card Exchange data. The front-end bus is the CPU and the outside Exchange data the most main channel, therefore the front-end bus's data transmission ability to the computer overall performance function is very big,

There are many things we need to pay attention to when using Python DNA sequences. In fact, there are many problems in constant learning. Next we will look at in detail how to conduct related technical schools. Ms is my brother's rotation project: Given A bunch of Python DNA sequences, that is, A string consisting of characters A, C, G, T, count the occurrence frequency of all subsequences whose lengths are n. For example, ACGTACGT, the sub-sequence l

ObjectiveThe timer on STM32 is powerful, and it is estimated that not many people have studied all the functions of the STM32 timer (including me), just use some of the usual features, and later I will introduce more features about the STM32 timer.STM32 chip Most of the 16-bit count, but basically there are 1 or two 32-bit timers, unfortunately, we most often use the F1 series of chips do not have 32-bit timers, F030 do not, specifically, see the data sheet.Today the main summary about STM32F0 s

following rules: Here, U is the frequency field variable, X is the gray value, and f (x) is the statistic corresponding to the gray value. After the histogram is transformed by DCT, the spectrum image is obtained. According to the original idea, filtering out the high-frequency part can smooth the waveform. Low-pass Assume that an ideal low-pass filter is used, that is, a threshold value of

How to change the screen refresh frequency in LINUX-general Linux technology-Linux technology and application information. The following is a detailed description. I installed red hat. How can I modify the screen refresh frequency? Several feasible methods 1. Install the nvidia or ati graphics card driver first. 2. Run it on the console. # Xvidtune There will be a graphical tool for setting the display, use

Fin: Crystal Oscillator frequency M: PLL0CFG [] N: PLL0CFG [] FCCO: PLL output frequency (Phase Lock output frequency) = Fin * 2 * M/N (this is not the case with the calculation formula of S3C2440, for more information, see datasheet) CCLKSEL []: The frequency division value. Set the

Frequency is the most commonly used function for calculating the number of consecutive times. Next we will provide a detailed illustration of this function in the application of the number of consecutive times.First, we need to understand the computing principles of frequency functions.Freqency (Data region, used to set an array of interval separation points)Purpose:Simply put, there are several numbers in

1 PrefaceThe modern induction heat treatment technology is widely used because of its high quality, high efficiency, and environmental protection. As the basis of induction heat treatment technology, the IGBT module of the inverter has been commercialized and has successfully produced 10 ~ 100 kHz IGBT inverter power supply with hundreds of kilowatts of power. Practice has proved that the use of IGBT variable-frequency power supply can completely repl

Card adds a lock to the warehouse and only has a key (password) can be opened for use. The CPU card is like a dedicated guard warehouse with a CPU chip in it, and the password for storing data needs to be verified. Different applications may have different passwords, so data access is more strictly controlled, the highest security. Non-contact IC cards use magnetic fields to obtain energy from the reader and exchange data. The magnetic field here is usually called the radio

In fast circuits, the project Master often recommends adding 33ω series resistors on the fast bus for three reasons: For impedance matching can reduce the voltage fluctuation and ringing effect, reduce the edge of the signal steep degree, reduce high-frequency noise and overshoot Also easy to debug I use the clock frequency 50MHz when I debug DSP6713 to access the SDRAM bus.The first P

Method One, turn off the core frequency through the BIOS First in the computer when the boot press F2 into the BIOS interface, and then move the cursor to the advanced advanced settings inside, advanced Frequency/voltage control, and then find and open power technology, select enabled, Then press F10 to save it. Method Two, use power management to turn off the core

The display's refresh frequency is the field frequency, measured in Hz. The higher the frequency of the refresh, the more stable the screen display, the smaller the flicker. In general, the display of the refresh rate of more than 75Hz, the user's eyes on the basic sense of flicker, 85Hz above the total no flicker. and the minimum

Keyword density and keywords word frequency, this is the site optimization of the more important part, because the search engine collation, which is very influential. Today to combine some of my small experiments, say keyword density and keywords word frequency bar. First of all, a brief talk about the site keyword density and keywords word frequency concept. In

Screen refresh frequency is actually a very abstract head, it is a graphic image on the screen by the electron beam hit and light-emitting fluorescence points, because the cathode ray tube in the phosphor by the beam after the light of the time is very short, so the electron beam must constantly hit the phosphor to make it continue to glow. The electron gun starts with the first line in the upper-left corner of the screen, scan from left to right, the
