NexRTOS x86 Real-time Linux Control System

NexRTOS is an x86 Linux-based Real-time control system that enables real-time capabilities for complex machinery performing high-precision motion control, computer vision and critical applications in micro second, such as CNC, robot controller, injection machine, packaging machine, and so on.

The independent ISR(/IST) performs guaranteed response-time for application through exclusive CPU core and isolated system resource. The CPU cores and LAN ports can be configured intuitively and the NexRTOS Utility can monitor the signal latency and time-jitter.

The IGH EtherCAT sample project code can accelerate the development of EtherCAT-based motion applications of servo drives/motors and distributed I/O for OEM partners and machine/equipment builders.
