Adaptive Real-Time



Minimal Real-Time Operating System for Embedded Applications

MaRTE OS is a real-time kernel for embedded applications that follows
the Minimal Real-Time POSIX.13 subset.

MaRTE OS allows executing concurrent, real-time Ada, C and C++
applications on a bare PC. Also Java (RTSJ) applications can be executed on MaRTE OS when it is configured as a Pthreads library for Linux.

MaRTE OS is being developed in the University of Cantabria, Spain, by the group of Computers and Real-Time Systems. The University of Cantabria is a member of the Adaptive Real-Time Cluster in the ARTIST2 Network of excellence.

The development environment is based on the GNU compilers GNAT , GCC and GCJ. Most of its code is written in Ada with some C and assembler parts.

Main characteristics of MaRTE OS

  • Open source (GPL)
  • It follows the minimal Real-time System Profile (PSE51) defined in
    POSIX.13 standard.
  • Provides concurrency at the thread level
  • Is targeted at embedded real-time applications.
  • Is targeted at static applications (all resources preallocated and number configurable at compilation time).
  • All services with a time-bounded response.
  • Single and unprotected address space. Shared by kernel and application.
  • Multilanguage: supports Ada, C, C++ and Java applications. In mixed
    language applications, a coherent scheduling is performed amon threads written in different languages.
    Although originally intended for embedded systems, MaRTE OS has been
    also adapted to behave as a POSIX-threads library for the Linux operating system.
