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 ...
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).
The STM32H7 Series is the first series of STM32 microcontrollers in 40 nm process technology and the first series of ARM Cortex-M7-based microcontrollers which is able to run up to 600 MHz, allowing a performance boost versus previous series of Cortex-M microcontrollers, reaching new performance records of 1284 DMIPS and 3174 CoreMark.

RL78/G13 integrates a +/- 1% accuracy on-chip oscillator, watch dog timer, RTC, power-on reset, low voltage detection, 26 channels of 10bit ADC, 16x16 Multiplier, 32/32 Divider, I2C, CSI/SPI, UART, LIN, multi-function timer array and also built-in IEC 60730 safety support in hardware. This combination of elements enables the system designer to ...
The Intel 8253 PIT was the original timing device used on IBM PC compatibles.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.
This allows software to manage latency by giving time-critical interrupts higher priority (and thus lower and more predictable latency) than less-critical ones. Trigger rate. When interrupts occur back-to-back, microcontrollers may avoid an extra context save/restore cycle by a form of tail call optimization.
The Low Voltage Series include the MSP430C09x and MSP430L092 parts, capable of running at 0.9 V. These 2 series of low voltage 16-bit microcontrollers have configurations with two 16-bit timers, an 8-bit analog-to-digital (A/D) converter, an 8-bit digital-to-analog (D/A) converter, and up to 11 I/O pins.
