At the end of this unit you should be able to

1. Trace an execution of a MIPS assembly program
2. Translate C code to MIPS assembly, including
   1. Assignment statements
   2. Basic arithmetic (+,-) and bitwise operations (~, &, | , < <, and > >)
   3. if-else statements
   4. switch statements
   5. for, while, and do-while loops
   6. Boolean logical expressions (&&, | | , !)
   7. Array accesses (reads and writes)
   8. Pointer arithmetic and dereferencing
   9. Function calls with parameters and return values
3. Distinguish MIPS instructions from pseudoinstructions
4. Identify the value of a load byte operation on the big-endian MIPS architecture after a store word operation
5. Identify the format of a given MIPS instruction (e.g., R, I, or J)
6. Write MIPS procedures that obey calling conventions
7. Save/retrieve values onto/from the call stack
8. Convert between a MIPS assembly instruction and its machine code representation
9. Identify the addressing mode of any MIPS instruction that changes the PC
10. Calculate the numerical value of BranchAddr for a branch address in a branch instruction, given MIPS assembly code including the target label
11. Identify the range of addresses available to a jump or branch instruction
12. Explain the tasks of the compiler, assembler, and linker (respectively)
13. Provide the contents of the relocation and symbol tables in an object file, given a C or MIPS program
