ReconOS is a programming model, an execution environment, an operating system extension, a hardware architecture, a research project, and a development playground.

Developed within the context of a university research project and a PhD thesis, and released under the GPL, ReconOS is a way to bring some of the convenience of a software-like programming model to the detail-ridden world of reconfigurable hardware design. With ReconOS, you can model a concurrent application for reconfigurable systems-on-chip (rSoC) using both software and hardware threads. The interactions between all threads are handled through common POSIX-like abstractions such as mailboxes, semaphores, or shared memory, hiding the complexities of bus access protocols, memory spaces, register files and interrupt handling.

ReconOS is actively looking for contributors! To get involved, check out the documentation, the wiki, the source code and the mailing list.
