scmRTOS
Breif Description
scmRTOS is tiny Real-Time Preemptive Operating System intended for use with Single-Chip Microcontrollers. scmRTOS is capable to run on tiny uCs with as small amount of RAM as 512 bytes. The RTOS is written on C++ and supports various platforms.
List of supported platforms for now:
- MSP430
- AVR
- Blackfin
- ARM7
- Cortex-M0
- Cortex-M3
- Cortex-M4
- STM8
Key Features
###Small ####Very small footprint:
- from 512 bytes of RAM
- from ~1K code
###Fast ####Minimal process switching latency:
- 900 ns on Cortex-M4 @ 168 MHz
- 1.8 us on Blackfin @ 200 MHz
- 2.7 us on Cortex-M3 @ 72 MHz
- 5 us on ARM7 @ 50 MHz
- 38-42 us on AVR @ 8 MHz
- 45-50 us on MSP430 @ 5 MHz
- 18-20 us on STM8 @ 16 MHz
###Modern ####Written entirely on C++:
- High reliability
- Simplicity and ease-of-use
###Extensible ####Extensions mechanism at kernel level:
- User defined extensions
- Debug features
