The SimpleScalar Architectural Research Tool Set consists of compiler, assembler, linker, simulation, and visualization tools for the SimpleScalar architecture. With this tool set, the user can simulate real programs on a range of modern processors and systems, using fast execution-driven simulation. We provide simulators ranging from a fast functional simulator to a detailed, out-of-order issue processor that supports non-blocking caches, speculative execution, and state-of-the-art branch prediction.
