38.  Implement the following expression in assembly language, using 32-bit integers (you may modify any registers you wish):

eax = -dword1 + (edx - ecx) + 1

 

You can use this data definition for testing your code:

dword1 DWORD 10h

39. 

se the following data declarations to write an assembly language loop that copies the string from source to target. Use indexed addressing with EDI, and use the LOOP instruction

source  BYTE  "String to be copied",0

target  BYTE  SIZEOF source DUP(0),0

 
 
 
 
 
 
 
 
Expert Solution
Step 1

Introduction:

In assembly language, you can manipulate data and perform operations on it using registers and instructions. In this particular task, we have been given an expression to implement using 32-bit integers. We will be using the EAX, EDX, and ECX registers to perform arithmetic operations on the given data. The expression involves adding, subtracting, and assigning values to the EAX register based on the values of other registers and a constant. Additionally, we will also be using the LOOP instruction and EDI register to copy a string from the source to the target. The source and target are defined using the BYTE data type, and we will be using indexed addressing to access the data.
