ROME is a modular, multitasking, embedded operating system which has been developed and used for multiple research projects within the Computer & Communications Research Laboratory (CCRL) of NEC USA, Inc. in Princeton, NJ. ROME was designed to manage high speed data streams within a multimedia environment. The system splits functionality over multiple processes which are communicating via a low overhead messaging mechanism. ROME supports TCP/IP networking, DOS FS, and provides a GUI toolkit. ROME systems can be built and customized using the ROME Target Builder, a graphical cross platform configuration tool.
