Enea Linux provide a high performance implementation targeting both macro/micro cells and small cells that are based on Freescale QorIQ and StarCore devices as well as the new OorIQ Qonverge SoC series platforms (BSC, B series, and G series). The Enea Linux Base Station Platform provides a superior foundation for base station equipment manufacturers to add the LTE/HSPA protocols of their choice. The unique value of the Enea Linux Base Station Platform offering over others is in the underlying implementation that features many innovations for performance and scalability: a) a novel Linux Light-weight Threading (LWT) model and interrupt handling that offers 10x the performance of Linux pthreads and real-time preemption patch in Linux user space, and b) Enea PAX - Packet Acceleration Foundation, that offers superior packet processing performance with exceptional configuration and programmability.
