Speculative Tomasulo Implementation

This is term project for CMSC-611 Advance Computer Architecture. This project generates a Tomasulo Algorithm Simulation Environment with GUI.

Dependencies

Use the package manager pip to install PyQT.

pip install PyQT

Usage

To run the project, run the file tomasulo.py

python tomasulo.py

To change the program(set of instructions) that is ran in simulation, make changes in the Config.py file.

Description of variables that can be altered:

num_of_register : number of total registers in the system

instruction_win_size : size of the instruction window

rob_size: size of reorder buffer

functional_units : list of available functional units

Supported instructions

ADD Dest, Source1, Source2    // Dest = Source1 + Source2
SUB Dest, Source1, Source2    // Dest = Source1 - Source2
MUL Dest, Source1, Source2    // Dest = Source1 * Source2
DIV Dest, Source1, Source2    // Dest = Source1 / Source2
LD  Dest, Source1, Source2    // Dest = Value 
BGE Source1, Source2, Location   // Branch to Location if Source1 greater than or equal to Source2
BNEZ Source1, Location   // Branch to location if Source1 not equal to zero
BEQZ Source1, Location   // Branch to location if Source1 equal to zero
