According to the S3C2440 official manual: fclk is used by ARM920T,Hclk is used for AHB Bus, which is used by the ARM

The clock isYou do not need to use the global clock resource bufg in FPGA to control the trigger clock along the input end.InsteadThe signal generated by the combination logic and oth

In the field of logical design, only a single clock domain is involved in the design of a few. Especially for some complex applications, FPGAs often need to communicate with signals from multiple clock domains. There may be a phase difference between the two clocks involved in an asynchronous clock domain, or there may be no frequency relationship, that is, a dif

Many of the packages feel that custom view is a symbol of a master, not actually. People think that the custom view is difficult in many cases because the custom view involves too many classes and APIs to make people dizzy, so today we will start with the simplest drawing API, and take you step-by-step into customizing the view world.Let's take a look at one we're going to implement today:The whole effect is simple, is to display a clock on the screen

Clocks are the most common in life, but it takes a certain amount of thought and time to make them, so take a look at this tutorial. Clocks are the most common in life, but it takes a certain amount of thought and time to make them. The following tutorial will describe how to make a clock. The author is very meticulous, basically every step has a detailed description, like a friend can try. Final effect 1, New document: 2304 * 1708 px, resolution:

1. Enter the CCS environment, load the existing project, load the generated. Out file, and find the code to view the code execution cycle. 1.Figure 1 1. Select enable clock in profiler of the CCS menu ,.Figure 2 2. select the clock setup sub-menu under the profiler menu, and enter your DSP clock cycle in instruction cycle. The unit is nanoseconds. For example, 24

During the hardware design of the product, EMI should be considered at the beginning of the design to reduce the financial and human resources required for subsequent rectification. This paper uses the clock signal as an example to design EMI to reduce radiation interference. (1) Schematic Design 1. the power supply of the clock chip is separated from other power sources by magnetic beads. The decoupli

The clock speed not only can update the system clock from the NTP server, but it can also calculate the clock frequency and manage the system time accordingly. Many people who want to keep an accurate computer clock use network time Protocol (NTP) to set their clocks at the same times as the atomic clocks. NTP is a wa

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

For the OK6410 clock part, we can find the relevant system controller in the system controller from the initi6410 manual: Power indicates Power-on. After the Power-on is stable, the 12 M crystal oscillator is also stable after the vibration starts. Then, the CPU can obtain a relatively stable clock frequency (12 M). If you want to change the frequency of the crystal oscillator, we will give him a locktime

The following figure shows the system clock schematic of 6410: Of Formula for determining the clock frequency of 6410: fout= Mdiv * FIN/(pdiv * 2 ^ sdiv) The values (mdiv, pdiv, sdiv) are in apll_con and mpll_con. Fin is the input clock of our system, and ok6410 is 12 MHz. To get the final output clock, you must set th

In MSDN, the check for the clock function is defined as follows:clock_t clock (void);Returns the time that the program consumes the CPU from startup to function calls. This function returns the number of CPU clock ticks (clock ticks) from "Open this program process" to "call clock
