    QP Real-Time Event Frameworks & Tools

    QP Real-Time Event Frameworks & Tools

    Real-Time Event Frameworks based on active objects & state machines

    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 microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows.

    Featureless Linux Library

    Featureless Linux Library

    Linux Library on top of Libc focusing on long term support.

    When computer power increases, programmers generally add more "features", thus making any performance gains in new hardware negligible. This project is an attempt to develop a library above libc that breaks out of this terrible loop.

    Recursive LDD

    Recursive implementation of List Dynamic Dependencies (LDD)

    Recursive LDD (recursive-ldd) is a Perl script that allows displaying a tree-like hierarchy of shared library dependencies. The script calls on the standard Linux ldd utility in a recursion for every listed binary and library. It completes running when no matches are found in the current branch. It can also print unique values only as well as environment variables that affect the loading of libraries: LD_LIBRARY_PATH and LD_PRELOAD. Same limitations to standard ldd apply. Recursive-ldd cannot check libraries without read permissions.

    BMDFM

    BMDFM

    Binary Modular DataFlow Machine (BMDFM)

    Binary Modular DataFlow Machine (BMDFM) is a software package that enables running an application in parallel on shared memory symmetric multiprocessing (SMP) computers using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly dynamic scheduling of the dataflow instruction sequences derived from the formerly sequential program. The BMDFM dynamic scheduling subsystem performs a symmetric multiprocessing (SMP) emulation of a tagged-token dataflow machine to provide the transparent dataflow semantics for the applications. No directives for parallel execution are needed. More info: http://www.bmdfm.com
