This project is an educational simulation of theTomasulo algorithm, a hardware algorithm for out-of-order scheduling and execution of computer instructions, written in C++.

Below are some of the key concepts of the simulation's algorithm:

• Reorder Buffer: simulates branching resolution using a reorder buffer
• Register Renaming: a technique to minimize data hazards
• Result Buses: unlike the original Tomasulo algorithm, which contains a singleCommon Data Bus (CDB), there can be multiple result buses to update the state of the pipeline.
• Reservation Station Scheduling: units of scheduling managing an instruction fired to aFunction Unit
• Specialized Function Units: specialized hardware units specific to different types of instructions
• Gselect Branch Prediction: a global branch prediction scheme that keeps a pattern history table and concatenates the global branch history
