# Super-Simple Tasker (SST) Version 2
Super-Simple Tasker (SST) is a **preemptive, priority-based RTOS kernel**
fully compatible with the requirements of [Rate Monotonic Analysis/Scheduling
(RMA/RMS)](https://youtu.be/kLxxXNCrY60).
This repository contains the **modern version of SST** (version 2).

# Hardware RTOS for ARM Cortex-M
SST version 2 provides a unique **hardware implementation**
of the preemptive, priority-based RTOS kernel for all ARM Cortex-M CPUs
(M0, M0+, M3, M4, M7, M23, M33).

> **NOTE**<br>
SST is likely the most performant and efficient **hard-real time RTOS**
kernel for ARM Cortex-M.

# History
SST has been originally published as a cover-story article
["Build a Super-Simple Tasker"](sst1/Super-Simple-Tasker.pdf) in the
Embedded Systems Design magazine in
[July 2006](https://www.embedded.com/embedded-systems-design-july-2006).
That original version of SST (now called SST1) is [still available](legacy)
and is provided for historical reference.

Over the years, more mature and complete SST-like kernels have been
developed for a number of embedded processors, such as: ARM Cortex-M (M0-M7),
MSP430, PIC24/dsPIC, PIC32, etc. Examples include:
- [QK ("Quantum Kernel")](https://www.state-machine.com/qpc/srs_qk.html),
which  works exactly like SST and is integrated with the
[QP Real-Time Embedded Frameworks (RTEFs)](https://www.state-machine.com/products).

- [QXK ("Quantum Extended Kernel")](https://www.state-machine.com/qpc/srs_qxk.html),
which combines the basic-tasks of SST with traditional blocking threads.
