一个mips虚拟机非常好代码,使用C++来编写的,希望大家多学学,

The following need to be completed.

Koala:

- coprocessor 1 (FPU) and related instructions
- unaligned memory accesses ("unaligned.cc")
- CACHE
- memory latencies
- correct interrupt handling in the D pipeline stage
- most pipeline slips, interlocks and other stalls
- second ITM slip on non-branch instructions
- wasted cycle on nullified instructions
- write buffers and SYNC
- warning messages when entering an undefined CPU state
- enable multiprocessor support (this is simple but involves further
  complication of the pipeline structure)

Other:

- implement access to the simulator state from within TCL
- implement TCL annotations
- there should be an ultra-fast MIPS64 JITC-based simulator somewhere
