Archimulator国产纯Java多核体系结构模拟器

Archimulator 国产纯Java多核体系结构模拟器：

• Written in 100% Java with the aid of JNA (Java Native Access) for native POSIX syscall implementations, which assures its portability and usability across many Linux machine configurations.

• Facilitates interface-based hierarchical object orientation to improve code readability and extensibility.

• Provides functional architectural simulation of:

  • Program loading for statically-linked MIPS32 ELF executables (both Little Endian and Big Endian are supported);
  • Functional execution of common integer and floating-point instructions of MIPS32 ISA;
  • Emulation of common POSIX system calls;
  • Execution of Pthreads based multithreaded programs.

• Provides cycle-accurate microarchitectural simulation of:

  • Separate pipeline structures such as the reorder buffer, separate integer and floating point physical register files;
  • Explicit register renaming based on the merged architectural and rename register file model;
  • Single-threaded superscalar out-of-order execution, multithreaded SMT and CMP execution model;
  • Multi-level inclusive cache hierarchy with the directory-based MESI coherence protocol;
  • Simple cycle-accurate DRAM controller model;
  • Various kinds of static and dynamic branch predictors, checkpointing-based pipeline recovery on branch misprediction.
