Assume that the program counter (PC) is set to 0x00000000. Describe how each of the instructions below could be used to set the next value of PC to 0x0FFFFFFC: j beq, jr, jal, bne Please do not just define what each instruction does and please do not give a random example thanks

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.
