DMUEMU

DMUEMU is an open-source emulator framework designed to simulate DMU hardware environments. It provides a modular platform that enables researchers, educators, and hobbyists to model a range of DMU devices, from processor cores to peripheral subsystems, without needing physical hardware. The project emphasizes flexibility, software-level accuracy, and extensibility through a plugin-based architecture.

Core components include an event-driven scheduler, a memory model, and a hardware abstraction layer that isolates guest DMU software from host architecture. The plugin system allows device models to be added or replaced, including CPUs, memory controllers, buses, timing units, and custom DMU peripherals. A scripting interface, typically with Python, supports automation, testing, and rapid prototyping, while configuration is described in human-readable files to enable reproducible setups across platforms.

DMUEMU aims to support multiple host platforms, provide snapshot and restore capabilities, and deliver debugging tools such as integrated debugging interfaces, memory and I/O tracing, and logs. Optional visualization or hardware-in-the-loop features may be included to assist in validating firmware and system software in controlled environments. The project prioritizes portability, reproducibility, and a permissive license to encourage community contributions.

Development is community-driven, with governance through a public repository, issue tracking, and contribution guidelines. The project is commonly used in academic research to prototype DMU architectures, in education to demonstrate embedded systems concepts, and in industry for preliminary firmware validation before hardware fabrication.
