Spring Project
Realtime microkernel and integrated environment, designed and implemented to support/provide predictability, guarantees (on-line dynamic, atomic), end-to-end scheduling, resource reservations; supports call/task admission model; and multiprocessors.
http://none.cs.umass.edu/rts/spring.html
Chimera
Multitasking, multiprocessor OS with features of commercial realtime OSs; as fast as VxWorks, OS-9, VRTX, LynxOS; 10 times faster in some cases: interprocessor communication. VMEbus-based, supports C/C++, goal: support developing dynamically reconfigurable software for robotic and automation systems.
