  2. Today • Course Syllabus • Course web page: http://www.cs.utsa.edu/~qitian/CS3843/ • What to cover? • Lecture notes and slides • Chapter 2: lecture notes most of time • Chapter 3 and 4: lecture slides most of time • Chapter 2.1 Conversion between different numbering systems • To do list: • Skim Chapter 1 • Read Chapter 2 through 2.1.10 • Understand how to convert between different numbering systems

  3. What to Cover? • Chapter 2 • Representing and Manipulating Information • Chapter 3 • Machine-Level Representation of Programs • ATT Assembly Language (IA32) • Chapter 4 • Y86 Instruction Set Architecture • Logic Design (combinational and sequential circuits)

  4. Chapter 2 - Representing and Manipulating Information • Conversion between different numbering systems • Based R representation and its conversion to decimal • Conversion between decimal, binary, and hexadecimal • Integer and Fraction part • Binary representation of n-bit word for signed and unsigned integers • 2’s, 1’s complement and sign/magnitude • Boolean operators and logical operators • &, |, ^, ~ • &&, ||, ! • Shift operators (<<, >>A, >>L) • Number representations using different data types (int, short, char, long) • n-bit IEEE floating-point representation • S, M, E, bias, exp (k bits), frac (n bits) • Single precision and double precision • Normalized, denormalized, special values (+/- inf, NAN) • Largest, smallest value • Rounding • Round-to-even; Round-towards-zero; Round-down, Round-up

  5. Chapter 3 - Machine-Level Representation of Programs • Understand all the IA32 assembly instructions, different operands and memory addressing modes; • Understand assembly codes and write correct comments; • Understand conditional codes (ZF, SF, OF, and CF) • Identify and correct any mistakes in given assembly instructions; • Write C codes from the given assembly codes and vice versa • Trace the register values in given assembly procedure

  6. Chapter 4 – Processor Architecture • Y86 instruction encodings • Translate object code to assembly code • Translate Y86 instructions to object code • Truth table and basic block diagram of logic gates (AND, OR, NOT, XOR, NAND, NOR), MUX, ALU, 1-bit full adder • Function complete set • Combinational circuits and sequential circuits • SEQ and six basic stages • Trace the processing of the instructions
