Part I
a.   Class Intro, HW and Program Execution
- syllabus(pdf)/addendum(pdf), - faq: grades, honesty, readable code, submit assignments, CAP, software - If you miss class, it is YOUR responsibility to get missed material - I will take attendance - QUIZZES - YOU will be doing code like this: ASM Code and Mixed C++ and ASM Code - Day One Quiz (C#) - About HW: where programs execute - emu Hardware - microsim: hardware - Bits, Bytes and Nybbles
b.   Number Bases: Unsigned Numbers in Base 2,8,10, 16
        - Code In Paint 
        - Base 2,8,10,16 and Unsigned Integers        
        - emu: number systems 
        - formula for n-bit unsigned binary number
            range: low to high, 0 to 2n - 1
c.   Signed Integers and IEEE 754 Floating Point
        sign-magnitude 
        one's complement
        Representing Signed Integers in "two's complement" notation 
        formula for n-bit number range
        Representing Floating Point Numbers
d.   Character Data: ASCII, Unicode and UTF
        Representing Characters: 7 bit ascii + code pages
        Representing Characters: unicode and utf-8 and utf-16
        Base 64: sending 8 bit clean characters
          ( 3 8-bit characters => 4 6-bit symbols )
        decode base 64
        images to base 64
u.   MicroControllers & Microsim
About microcontrollers & MicroSim 5.0 Architecture: 256 BYTES of RAM Using the Simulator Download MicroSim 5.0 Online Manual First Program Microsim5 folder - open with launchy (sms32v50.exe ) Run demo1.asm in Microsim and look at RAM (sms32v50.exe)
e.   Using emu8086
emu8086 reference: about the emulator emu: intro
create open debug/step
f.   Instruction Codes, List Files
Representing Instructions List Files from the Assembly Process Example asm code - list file shows machine code
g.   Organization of CPU Registers and Memory
store and move data & information DB, DW, MOV, endian emu CODE with library procs and macros list file * put into emu8096 emulator * examine list file
h.   Assembly Language Intro: basic instructions, flags
assembly language intro arithmetic and logic instructions what is assembly & why the asembly process mov flags (C Z S O) add, sub,cmp, and, test, or, xor mul, imul, div, idiv inc, dec, not, neg truth tables XCHG, AND, OR, XOR, NOT Masks: (and, or, set, clear) & Architecture and, or / clear, set masks xor encrypt, decrypt, clear fast
i.   Flags, Compares, Jumps and Loops: Flow Control / Overflow!
loop review flags flow control: jmps overflow cmp jump masks see if set? jz jnz flags not set by mov emu debugger jz with ret label loop jmp
j.   Procedure Calls, Stack and Macros
Procedures Stacks emu: procedures emu: the stack MACRO simply expanded inline CALL IP points to NEXT instruction past Call IP Pushed on stack IP adjusted by offset which is included in instruction Execute Proc Ret pops stack into IP Isolate functionality Save and restore registers unless returning value pusha, popa
k.   Addressing Modes
16 bits => 1MB ?? magic? ea (effective address) = Segment x 16 + IP cs = 0700, ip = 010f ea = 07000 +010f 0710f there are 16 64k segments in the 1 megabyte address space of the 8086, emu: mov & memory access
  ∴   Test1 - Mid Term Exam: M() & W()
TEST 1 Review Create a CAP List Files Endian
Part II
l.   Pointers and Arrays
pointers and arrays loop and add WORDS in an array loop and add BYTES in an array -- documented (local)
m.   Maze Intro
Maze assignment symbol table ptr lea labels location counter
n.   Looping thru an Array of Bytes and Printing: Maze
maze intro maze loop drawMaze (local) cmp - sets zero flag jz, je jnz, nje pusha, popa asm in visual studio 2012
o.   Interrupts to Read and Write
interrupts read int 16h, ah=0 write int 10h ah= 9 or 0ah int 21h putc call print 8086 interrupt list
p.   DIV, MUL Use Multiple Registers | Magic?
DIV, MUL 64 bit arch introduces new registers useless mov speeds code up intel micro-architecture complexity in branch prediction and cache
q.   Mixed Code Intro
mixing high-level and low-level code mixed code example - simple
r.   Mixed Code: C++ and ASM
high-level code generates low-level code mixed code example asm code called by cpp example
s.   Mixed C with ASM
changing code when there is no source code smallest elf code binary: hello about apollo: 16 bit, 2k ram, 36k fixed program the apollo main.c myCproc.c myAsmProc.asm
t.   emu8086 MicroController: Devices
Stepper Hell Devices I / O
v.   Architecture I, II, III
architecture intro architecture: digital logic architecture: build a cpu logic.ly intel history animated CPU (by former student jason green)
  ∴   Test 2 - Final Exam: Wednesdy at 8am and 10am
TEST 2 Review Create a CAP CUP Registrar: see "Final Exam Schedule" Wed 8am ugh
