The gem5 simulator is an open-source system-level and processor simulator. It is utilized in academic research and in industry by companies such as ARM Research, AMD Research, Google, Micron, Metempsy, HP, and Samsung.[1][2] Arm has developed further software called Streamline for developers working with gem5 which aims to present "a graphical view of system execution".[3]
History
The gem5 simulator was born out of the merger of m5 (CPU simulation framework) and GEMS (memory timing simulator).[4]
Features
gem5 is an event-driven simulator with multiple execution modes.[4]
- full-system emulation (simulating the whole OS) and syscall emulation (just user-space is emulated)
- multiple ISAs (Alpha, ARM, SPARC, MIPS, POWER, RISC-V, and x86 ISAs)[1]
- timing model for the full cache hierarchy with support for custom coherence protocols
- simplistic CPU, in-order CPU, out-of-order CPU
- serialize/deserialization from checkpoints
