7. For both of the instructions shown below, the initial conditions are shown. The result (which the instruction stores in r1) is also shown. For each instruction, answer these questions: • What is the state of the flags (NZCV) after the instruction executes • If the operands were signed, are the results valid? Why or why not? • If the operands were unsigned, are the results valid? Why or why not? a) initial conditions: r0 = 0xAAAA_AAAA rl=0x5555_5555 ADDS rl,rl,ro Result: r1=0xFFFF_FFFF b) initial conditions: r0=0x7FFF_FFFD r1 = 0x0000_000F ADDS rl,ro,r1 Result: r1=0x8000_000C

1. Execute the foiiowing instructions by hand, then find the final centents of X, Y and memory locati $C159 to $C159. Moving a Block of Memory from One Location to Ancther Algorithm Description In this prograH, we want to move the contents of block 1 ($CI00 to $CIO7) to block 2 ($C150 to'? This means that the contents of $C100 (44H) will move to the contents of $C150 and overwrite them and so on. After executing the program, the contents of the two blocks should be same. Remember, when we write any new data over existing data, the latter will be lost and replaced by the new data.

In Assembly language, The OR instruction can be used to generate the two's complement of an integer. True False
Do the following problems: Given the contents EAX: 58AD 2453H, EBX: 37CE 3A Show the values (states) of the following flags CF, ZF, PF, OF, SF, in EFLAGS, after the execution of the following instructions: a. ADD EAX, EBX b. SUB EBX, EAX
Given the machine code, identify the instruction line or command line. Use CAPITAL LETTERS . No spaces in the operand side. NO need to include "H" for any immediate or displacement value. e.g. MOV AX,BX GIVEN: 10101001 10101100 00111011
After the ROR instruction is executed in the code sequence below, what is the final value for AL? MOV AL, 1000 1111b ROR AL, 2 O a. The answer is 1110_0111. O b. The answer is 1100_0011. O. The answer is 1110_1011. O d. The answer is 1110_0011.
Because of this, the means by which one instruction acquires its input data are independent of the means by which another acquires its data. When used with a(n): A Combining sets of data with sets of instructions B An example of "multiple data, multiple instruction" C D is for "data alone," meaning there is just one instruction. One order, several results
Differentiate between the two instructions: MOV BL, [SI+06H] and MOV CL, [BX+SI+06H]. Note: Please do not handwritten. Also, write the answer briefly and do not write too much.
Fill in the following table showing the results of the indicated instructions, using the register values shown. Also, show the OF and CF values AFTER the instruction executes. Show all results in hexadecimal. Show OF and CF as 0 or 1.
