scmRTOS embedded operating system

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
