Project 3. MIPS Pipelined Simulator

Skeleton developed by CMU, modified for AJOU SCE212.

Instructions

There are three files you may modify: util.h, run.h, and run.c.

1. util.h

We have setup the basic CPU_State that is sufficient to implement the project. However, you may decide to add more variables, and modify/remove any misleading variables.

2. run.h

You may add any additional functions that will be called by your implementation of process_instruction(). In fact, we encourage you to split your implementation of process_instruction() into many other helping functions. You may decide to have functions for each stages of the pipeline. Function(s) to handle flushes (adding bubbles into the pipeline), etc.

3. run.c

Implement the following function:

void process_instruction()

The process_instruction() function is used by the cycle() function to simulate a cycle of the pipelined simulator. Each cycle() the pipeline will advance to the next instruction (if there are no stalls/hazards, etc.). Your internal register, memory, and pipeline register state should be updated according to the instruction that is being executed at each stage.
