F´ (or F Prime) is a software framework for the rapid development and deployment of embedded systems and spaceflight applications. Originally developed at NASA’s Jet Propulsion Laboratory, F´ is open-source software that has been successfully deployed for several space applications. It has been used for but is not limited to, CubeSats, SmallSats, instruments, and deployable. Component architecture with well-defined interfaces. To develop applications with F´, the following requirements of...

QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal...

Simplest of possible ways to multithreading on the smallest microcontrollers. This project is demonstration the programming technique of the multithreading with polling the system state. Published code debugged and ready to use in your projects.

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics: - Memory and enhanced time partitioning (TSP) - Native support for sporadic, periodic and aperiodic threads - Fixed-priority preemptive scheduler - Execution time protection (threads are prevented from executing for more time than they are configured to) - Small size (full image has ~100 to 300KiB text, ~30KiB data) - Hard real-time determinism - Fast critical sections - Prioritized nested interrupts - inter-partition communication with filters to protect unwanted access - Multicore support (RMP) - Supports ARM9, Cortex-A/R/M and Aarch64, RISC-V64 (64 bits) - The complete TestSuite (see below information) is run successfully for each platform in each release - Tested: more than 170 KLOC of requirement-based tests, executed for each board at each release - Up-to-date User Manual also available See our wiki page for more information.

This project is now in the research and development stage. It is intended for very small microcontrollers with a single processor and represent simple multithreading kernel what written by C language. Is planning create implementations for AVR8 and STM8, may be. Now it is suspended until better time.

This project introduces new FPGA architectural tools and Linux OS modifications that aid in supporting Dynamic Partial Reconfiguration (DPR) on FPGAs for concurrent control. It shows that control systems benefit from hardware concurrency, meaning that by moving the control intelligence into hardware, the negative effects inherent to threads and their scheduler are minimized. This leaves software with the role of a high-level administrator rather than an executor, thereby eliminating unnecessary bottlenecks. The tools described in this project enable the hardware engineer to develop DPR-FPGA systems more effectively for rapid control system development.

Implementation of virtual threads for the XS-1. Currently a simple context switching implementation for the XMOS XS-1 architecture (Gn, Ln products). Allows a user to run low speed processes on a single thread using time sliced scheduling.

CellMT is a threading library for the Cell/BE that enables the concurrent execution of multiple threads inside each SPE. This project has been developed at the Computer Sciences department of the Barcelona Supercomputing Center. http://www.bsc.es
