Atalanta: A New Multiprocessor RTOS Kernel for System-on-a-Chip Applications

Abstract

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.
