Multitasking in Small Embedded Systems

Multitasking in small embedded systems can be a challenging task as it requires running multiple tasks simultaneously on a microcontroller or small microprocessor. Real-time requirements make the task even more complex as certain tasks need to be completed within a specific timeframe. However, FreeRTOS, a software tool developed and maintained by Real Time Engineers Ltd., can help developers build embedded applications to meet these real-time requirements.

  • Multitasking in small embedded systems means running multiple tasks simultaneously on a microcontroller or small microprocessor.
  • FreeRTOS is a software tool that helps developers create independent threads of execution for each task.
  • Real-time requirements are when certain tasks need to be completed within a specific timeframe, either as a “soft” requirement or a “hard” requirement.
  • FreeRTOS helps ensure that hard real-time tasks are always executed ahead of soft real-time tasks.
  • FreeRTOS is a real-time kernel or scheduler that helps developers build embedded applications to meet these real-time requirements.
  • FreeRTOS is professionally developed, quality controlled, robust, and free to use in commercial applications without any requirement to expose proprietary source code.
  • There is a low cost commercial upgrade path available for additional support or guarantees.

In conclusion, FreeRTOS offers a reliable and efficient solution for multitasking in small embedded systems. Its real-time kernel or scheduler allows developers to build independent threads of execution for each task, prioritizing hard real-time tasks over soft real-time tasks. With its professional development, strict quality control, robustness, and free availability for commercial use, FreeRTOS has become a popular choice for developers worldwide. The low-cost commercial upgrade path is also available for additional support or guarantees, providing peace of mind to developers who require it.
