RTXC Quadros RTOS -- flexible, adaptable, configurable
The RTXC Quadros RTOS family is four highly scalable real-time operating systems with distinct advantages for each of the major processing models.
RTXC/ss utilizes a lightweight executive for signal processing.
RTXC/ms is optimized for control processing with an event-driven, prioritized scheduler.
RTXC/dm (dual mode) is ideal for convergent processing which combines DSP/dataflow and RISC/control processing in a single-core.
RTXC/ms and RTXC/dm are brought together in RTXC/mp to support multicore/multiprocessor.
