The web page you are watching was served by a simple web server running on top of the lightweight TCP/IP stack lwIP running under GeMRTOS: the Generic embedded Multiprocessor RTOS for Altera FPGAs.
GeMRTOS is a native multiprocessor real-time operating system (RTOS) specifically designed for embedded systems. Built for flexibility, GeMRTOS supports a wide array of processors and configurations. Currently compatible with both Nios II and Nios V processors, it integrates seamlessly into Altera's Platform Designer, allowing for easy configuration and scalability. This adaptability makes GeMRTOS ideal for diverse real-time multiprocessor applications.
lwIP is an open source implementation of the TCP/IP protocol suite that was originally written by Adam Dunkels of the Swedish Institute of Computer Science but now is being actively developed by a team of developers distributed world-wide. Since it's release, lwIP has spurred a lot of interest and has been ported to several platforms and operating systems. lwIP can be used either with or without an underlying OS.
