Description
In this assignment, you will be adding MIPS conditional/unconditional branch instructions and procedure call instructions to the processor designed in Assignment 4. Make appropriate modifications to your code:
- Implement the following branch instructions using J-type instruction format: bne, beq, blez, bgtz, j.
- Implement the instructions used for procedure calls: jal, jr.
- Implement non-leaf procedures (procedures that can call other procedures) using stack.
- The stack should be implemented in memory and should grow downwards.
- You can assume that a maximum of four arguments can be passed to a procedure.
Once the desired modifications are done, you need to simulate and synthesize the modified VHDL processor model
