Some software watchdog timers are implemented as standard software modules. Examples of these include "Softdog", a virtual device driver which emulates an electronic WDT and conforms to the Linux watchdog API, [ 11 ] and MathWorks ' Software Watchdog Timer, a retriggerable one-shot timer which can be instantiated by dragging its GUI ...
This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
Simulates a PIC microcontroller: Logisim-evolution [4] [5] Multiple Universities 2024: Windows, macOS, Linux VHDL: Fork of Logisim (development ended in 2011) [6] LTspice: Analog Devices: 2024 Windows, macOS, POL: Very popular, updated often [7] Originally created at Linear Technology. Micro-Cap: Spectrum Software: 2021 Windows PLD expressions
It used a 1.193182 MHz clock signal (one third of the color burst frequency used by NTSC, one twelfth of the system clock crystal oscillator, [1] therefore one quarter of the 4.77 MHz CPU clock) and contains three timers. Timer 0 is used by Microsoft Windows (uniprocessor) and Linux as a system timer, timer 1 was historically used for dynamic ...
Precision Time Protocol (PTP) is a widely adopted protocol for delivery of precise time over a computer network. A complete PTP system includes PTP functionality in network equipment and hosts. PTP may be implemented in hardware, software or a combination of both. PTP is implemented in end systems and in PTP-aware networking hardware.
The design minimizes and separates 32-bit arithmetic so that it can be adjusted or optimized for 8 and 16-bit CPUs. Also, 16-bit software timers (common on small microcontrollers) can overflow and cause defective operation. This can be fixed with a timer system that does not overflow (e.g. the timers count down or use modular arithmetic).
CrossWorks for ARM by Rowley [10] Dave by Infineon. For XMC processors only. Includes project wizard, detailed register decoding and a code library still under development. [11] DRT by SOMNIUM Technologies. [12] Based on GCC toolchain and proprietary linker technology. Available as a plugin for Atmel Studio and an Eclipse-based IDE.
The usual interval is 1 to 10 milliseconds (1 ⁄ 1000 to 1 ⁄ 100 of a second) via an interrupt from a hardware timer, but this interval is often changed to suit a given application. The software distribution contains prepared configurations and demonstrations for every port and compiler, allowing rapid application design.
