#MIPS Emulator (Project 3) This is for my CSC 252 class.

This emulator implements a subset of the MIPS instruction set.

Please see these source code files for more detail:

• Instruction.[ch]
• RegFile.[ch]

Basic ideas:

• Five stages (IF, ID, EX, MEM, WB)
• Instruction "microcode" is specified by two things:
  • flags (16-bit) that specify ALU source, read/write, mem/reg, etc
  • ALU operation
  • note: I used struct packing for the flags; I use an ifdef for endianness to ensure that fields are stored in a predictable sequence in memory. I'm 92% confident that this should work the same way on big- and little- endian machines. My test machine was little-endian. (see Instruction.h and parts of Instruction.c for more detail)
• Branching/Jumping:
• save information, execute next instruction, branch/jump depending on conditions
• for bnel/etc we retire the next instruction by writing a nop
