Real-Time Executive for Multiprocessing Systems
RTEMS is a real-time executive (kernel) which provides a high performance environment for embedded applications with the following features:
- Standards based user interfaces.
- Multitasking capabilities.
- Homogeneous and heterogeneous multiprocessor systems.
- Symmetric Multiprocessing (SMP):
- Cluster scheduling: Job-level fixed prority scheduler (EDF) with support for one-to-one and one-to-all thread to processor affinities.
- Locking protocols with transitive priority inheritance, priority ceiling, MRsP and OMIP.
- Event-driven, priority-based, preemptive scheduling.
- Scalable timer and timeout support.
- Optional rate monotonic scheduling.
- Intertask communication and synchronisation.
- Priority inheritance.
- Responsive interrupt management.
- Dynamic memory allocation.
- Dynamic code loading using run-time link editing.
- File systems, IMFS, FAT, RFS, JFFS, NSFv4 (with LibBSD)
- High level of user configurability.
- Link-time configurable schedulers.
- Linker-set based initialization (similar to global C++ constructors).
- Drivers for I2C, SPI and LibBSD has NIC, USB, SD/MMC and Framebuffer.
- Open source with a friendly user license.
