QP actor frameworks and QM modeling tool

Compare

  No analysis available

QP is a family of lightweight software frameworks for building responsive and modular real-time embedded applications as systems of cooperating, event-driven active objects (actors). The QP family consists of QP/C, QP/C++, and QP-nano frameworks, which are all strictly quality controlled, superbly ... [More] documented, and commercially licensable. The behavior of active objects is specified in QP by means of hierarchical state machines (UML statecharts). The frameworks support manual coding of UML state machines in C or C++ as well as automatic code generation by means of the free QM modeling tool. See also http://sourceforge.net/projects/qpc [Less]

Fiasco

Compare

  Analyzed about 8 hours ago

Fiasco is a new µ-kernel (microkernel) running on x86 PCs intended to be compatible with the L4 µ-kernel for x86. It implements the L4 ABI as defined in the L4/x86 Reference Manual. The Fiasco kernel can be used to construct flexible systems. We at TU Dresden use it as a base for our DROPS ... [More] system which supports running real-time and time-sharing applications concurrently on one computer. However, Fiasco is not only suitable for big and complex systems, but also for small, embedded applications. [Less]

Cosmos (C# Open Source Managed Operating System)

Compare

  Analyzed about 8 hours ago

COSMOS (C# Open Source Managed Operating System) Cosmos includes a compiler (IL2CPU, which is part of Cosmos) that reads the input file (usually the shell) and Cosmos libraries and compiles the resulting IL to x86 code. IL2CPU has a layer for cross platform and we plan to support other processors ... [More] and platforms, including x64. IL2CPU also supports certain extension methods which allow C# code to interact directly with the CPU, registers, and ports in the kernel. IL2CPU contains some inline assembler, but there are no ASM files that need to be linked in. Currently IL2CPU first outputs raw asm files (with IL comments) and then processes them through nasm (a free assembler). Later we plan to emit directly to binary. [Less]
