In the offset mode, N copies of the same chunk will exist on a continuous disk at a continuous offset (one disk offset and one chunk offset ). Copies of each stripe are stored at the offset of one disk. If the chunk size is appropriate, the offset method can provide the same read performance as the far method, but the write performance is not as bad as the near method. The number of RAID

With the development of computers today, it is no longer the size of the big, limited to the government department to enjoy the big. Today it is small but powerful, stylish and no lack of perfect detail, the most representative product is the notebook computer. The appearance design, the structure material, the keyboard interface and so on have become more and more advanced in the decades time, more and more practical, but the core hardware like the processor and the graphics card has become the

A series of transformations in any order on any number of channels constitutes a group conversion. For example, the conversion can be completed in the following order: Channel 3, Channel 8, Channel 2, Channel 2, Channel 0, Channel 2, Channel 2, channel 15. When you perform a rule Channel Group Scan transformation, you can enable the conve

serial interface can be used. A complete conversion requires 24 serial synchronization clocks (DCLK) to complete. The first 8 clocks are used to enter the control byte via the din pin. When the converter obtains enough information about the next conversion, it enters the sampling mode. After 3 multi-clock cycles, the control byte setting is complete and the converter enters the conversion state. The next 12 clock cycles will complete a true analog-to-digital conversion, and the 13th clock will

Quality exception ball problems in 12 small balls measured three times without Weight Balance Original Title:There are 12 small balls with the same features, and only one of them has a quality exception. It is required to be called three times without a weight to find the ball with an abnormal quality.Solution:Set the standard ball quality to W, and represent any normal ball. Number the 12 balls A1, A2,..., and A12 in sequence:A1, A2, A3, and A4 are A1 groups.A5, A6, A7, and A8 are A2 groups.A9

better solution. Figure 6 shows an example of converting a single-ended signal to a differential signal.A major application of a fully differential amplifier is signal processing in the case of an ADC input. Low-pass filters need to be used to remove high-frequency noise to prevent their aliasing into the band of interest. Multilevel Feedback (MFB) is an excellent topology that is easily adapted to a fully differential amplifier. A MFB circuit is use

be used in the main ADC1. The internal reference voltage Vrefint is not the same as the reference voltage. The reference voltage of the ADC is provided by the vref+ and serves as the reference voltage for the ADC converter. When we use the vref+ directly from the VCC voltage, when the VCC voltage fluctuation is relatively large or the regulator performance is poor, the internal reference voltage of the STM

There are three ultimate propositions in Philosophy: Who are you? From where? Where to go? For the dapm mechanism, we can ask: What is dapm and what is its function? How is dapm created? How is dapm triggered? The following is an analysis of these three problems. First, what is dapm? This is mentioned in the overview of dapm, that is, the dynamic management of audio power supply. I believe that power management is not unfamiliar to everyone. The purpose of the dapm design is to enable the necess
