Study on auxiliary clock of AT91RM9200 Platform [Date:] Source: MCU and Embedded System Application Author: baili Ren nun, Lanzhou Jiao Tong University [Font:Large Medium Small] 　 IntroductionIn VxWorlks, the implementation of the timer mechanism is based on the clock. Different Timing mechanisms can be selected based on different requirements, such as taskDelay (), WatchDog, and auxili

Jitter is defined as the deviation of the signal from its ideal position. This article focuses on clock Jitter and discusses the following types of clock jitter: adjacent periodic jitter, periodic jitter, time interval error (TIE) jitter, phase noise, and phase jitter.Introduction to Clock JitterClock jitter is the deviation of the

The clock is the most important and special signal of the entire circuit. Most devices in the system are operated on the hop-on-line of the clock, which requires that the delay deviation of the clock signal be very small, otherwise, the timing logic status may be wrong. Therefore, it is very important to clarify the factors that determine the system

CPU clock speed, that is, the clock frequency (cpuClock speed ). In general, the CPU is as high as, And the is the "CPU clock speed ". Many people think that the CPU clock speed is its running speed. The clock speed of the CPU indicates the speed at which the digital pulse s

Article Title: linux tips -- set the clock and time. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Introduction: This document explains how to set a computer clock in linux, how to set your time zone, and other materials related to how linux saves time. Your computer h

This document explains how to set a computer clock in Linux, how to set your time zone, and other materials related to how Linux saves time. Your computer has two clocks. One is a always-running, battery (hardware, bios, or CMOS) clock, the other is the (system) Clock maintained by the operating system running on your computer. The hardware

, scalability, high efficiency, industry unity, good compatibility, portability strong; Xdc is essentially a TCL language, but it only supports basic TCL syntax such as variables, lists, and operators, and syntax for other complex loops and file I/O can be supplemented by a Tcl file in Vivado. (The reader who is interested in Tcl's topic can refer to another article by the author, "Tcl's application in Vivado") The main differences between XDC and UCF are two points: Xdc can be read a

STM32 clock System for a skilled microcontroller development should be more familiar, but for the novice without too many basic (such as I one months ago), see such a clock system diagram inevitably have a nod big, But when it comes to understanding the designer's purpose and then looking back at a picture like this, you'll find it's not a difficult thing to understand. STM32F103 has 5

Ⅰ , overviewFor the system clock should know its role, is to drive the whole work of the heart of the chip, if not, it is equal to the person has no heartbeat.For friends using board learning, the knowledge of the RCC system clock is not well configured, because the crystal oscillator provided by the board is basically the official standard clock frequency, using

Clock gate, English name gate clock. The so-called "door-control" refers to the logical output of one clock signal and another non-clock signal. For example, you use a control signal "and" CLK "to control the CLK's effective time.This is used in ASIC to reduce power consumption, because the power consumption is mainly

1. System interruption and clock cycle 1.1 system interruption Interrupt is a hardware mechanism that notifies the cpu Of an asynchronous event. Once the interrupt is identified by the system, the CPU stores partial (or all) context values, that is, the values of some (or all) registers, and jumps to a special subroutine, it is called the interrupt service subroutine (ISR ). Interrupt Service subprograms are used to process events. After processing is

in the STM32 if the external crystal is not used, osc_in and the Osc_out the method of connectionIf using an internal RC oscillator without an external crystal, proceed as follows:1) for 100 feet or 144 feet of products, osc_in should be grounded, osc_out should be suspended.2) for products with less than 100 feet, there are 2 kinds of mating methods:2.1) Osc_in and Osc_out are grounded by 10K resistors respectively. This approach can improve EMC performance.2.2) Remap osc_in and osc_out to PD0

Clock animations are also widely used in Web applications, and in some personal blogs we often see some fairly personalized HTML5 clock animations. Today we share with you 14 models of ultra-fashionable HTML5 clock animation, including disk clock, 3D clock, personalized

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

Tiny4412 is a new development board with less information and I am a little white. Therefore, there is no concept of clock configuration for camera. No way, it can only be viewed from the source code. Clock driver Overview The tiny4412 clock configuration source code is in/ARCH/ARM/Plat-Samsung/clock. c,/ARCH/ARM/Plat-

Beginner STM32, feel the most egg pain is its clock system, every time see its clock tree is a bit dizzy, although read a lot of this information, even has written a lot of STM32 module code, did some small project, but always still on this piece of vague, indefinitely, So I want to write a little bit of my knowledge of it, step-by-step, until the day of full straightened out, (these things are not original

This article from: http://www.openedv.com/posts/list/302.htmAuthor Zhang YangThe clock system is the core of the processor, so it is necessary to learn the clock system carefully before learning STM32 all the peripherals, which helps to understand the STM32 deeply.Here is a STM32 clock diagram from the Internet, which looks clearer than the one in the STM32 Chine
