Real-Time Edge Software

REALTIME-EDGE-SOFTWARE

Roll over image to zoom in

The real-time edge software enables real-time applications for the i.MX and Layerscape products and can be easily integrated with the Yocto SDKs for these products. Real-time edge software enables real-time capabilities via support for Preempt-RT for low latency applications, baremetal framework and support for real-time operating system (RTOS) on the Arm®-Cortex®-A or Cortex®-M cores. Real-time edge software also supports real-time protocols and stacks for IEEE1588 PTP network synchronization, time sensitive networking (real-time ethernet), EtherCAT leader, CANOpen and OPC-UA.

Complete with reference software a system-validated board support package (BSP), NXP provides you with the tools to test and maximize the performance of the applications you develop.
