A simulator for a superscalar out-of-order processor that uses Tomasulo's algorithm in Python.
python superscalar.py <asm file>
- 4-way superscalar out-of-order execution Pipelined Execution with 4 stages: Fetch, Decode, Execute and Writeback
- Multiple ALUs and Memory units and single Branch unit
- Reservation station for each unit type (Tomasulo’s)
- Static Branch Prediction - Always taken
- Blocking issue with Branch instructions
Since I worked on this project incrementally, I have some useful files or those who wish to build their own simulator. I have included a simple processor that isn't pipelined in simple.py. A pipelined version of this proccessor is present in pipeline.py. I have also included my presentation slides. They include the results of some interesting experiments!
