This paper introduces a new multiprocessor real-time operating system
(RTOS) kernel that is designed as a software platform for System-On-Chip
(SoC) applications and hardware/software codesign research purposes. This
multiprocessor RTOS kernel has the key features of an RTOS, such as
multitasking capabilities, event-driven priority-based preemptive scheduling;
and interprocess communication and synchronization. Atalanta has some features
important for SoC applications, such as a small, compact, deterministic, modular
and library-based architecture. Atalanta also supports some special features
such as priority inheritance, and user configurability. Atalanta supports
multiple processors with synchronization based on atomic read-modify-write
operations.
