  1. Midterm Review Introduction to Computer Systems Engineering (CPEG 323) \course\cpeg323-08F\Final-Review-323-08F.ppt

  2. Objectives of CPEG 323 • Acquire solid knowledge in the analysis, design, implementation and evaluation of computer system organization with emphasis on instruction-set architecture and optimization • Acquire basic knowledge of the interaction between system software (e.g. compilers) and hardware (architecture) design \course\cpeg323-08F\Final-Review-323-08F.ppt

  3. ABET Outcomes • Ability to apply knowledge of science (e.g., computer architecture and system organization, and related computer science issues), and engineering (e.g., performance analysis and benchmarking, ISA simulation and verification) • Ability to use the techniques, skills and modern engineering tools necessary for engineering practice • Knowledge of related topics in computer science discipline \course\cpeg323-08F\Final-Review-323-08F.ppt

  7. More about ISA … • 4 style of ISAs: • memory-to-memory • accumulator machines • stack machines • register based ISA • General vs. special purpose regs \course\cpeg323-08F\Final-Review-323-08F.ppt

  8. More about ISA … • MIPS memory model • data types and sizes • little vs. big endings • Register conventions • MIPS operations (3 types) • instruction format and fields • addressing mode • assembly vs. machine representation • RISC vs. CISC • Calling conventions and stack frames • caller save vs. callee save • parameter passing \course\cpeg323-08F\Final-Review-323-08F.ppt

  9. More about ISA … • System software and ISA • role of system software tool chain: compiler, assembler, linker, etc. • memory layout for C compilers • runtime stack layout • Interaction between ISA and OS • Privileged mode, traps, etc • Static vs. dynamic libraries \course\cpeg323-08F\Final-Review-323-08F.ppt
