New lecture slides, and Midterm grades are online now. 

Chapter 4 (slides), and assignment 4 are online now.

* The Midterm exam includes: Chapter 1,2,3, and Chapter 4 (Book: 4.1, 4.2  -  Slides:to slide 40).

* If you don't have enough time  to read book "Chapter 4", don't worry.  Reading the Slides, and doing "assignment 4" are enough to cover last lecture. 

* In the book, at the end of page 138 (pdf 109): Please correct the following sentence
"The Carry flag is exclusive ORed with the high bit of the result" ---> "The Carry out is exclusive ORed with the Carry in for the highest bit of the result"
Example: 
             mov al, 1
             sub al, 128  ; al=1000 0001
In this example, the actual carry out= 0. However, the x86 processor invert this value and state the carry flag, then CF=1. Meanwhile, the Carry in of MSB=1 in the result of this operation. 
Thus:
if it's Carry flag xor MSB:                then 1 xor 1 =0   (Wrong)
if it's Carry out xor Carry In of MSB: then 0 xor 1= 1   (Correct)

How it comes? 
 0000 0001      0000 0001
-1000 0000 ->+0111 1111
                    +             1
------------------------------------
                      1000 0001
CarryIn=1
CarryOut=0

Then CF=Inversion of CarryOut= 1
OF=CarryIn Xor Carryout=1

Add example:
  0000 0001                                      
+1111 1111                                   
-----------------                                                
  0000 0000                                     
CarryIn=1                                                              
CarryOut=1                                                            
Then CF=1, OF=0
