Consider the following assembly program MOV CX, 1100H DLY: SUBS CX, CX, #1 NOP BNE DLY NXT: --- (a) How many times does the BNE DLY instruction get executed? (b) Change the first line of the program so that BNE DLY is executed 34 times (c) Change the second line of the program so that BNE DLY is executed 34 times, while the fist line stays unchanged (MOV CX, 1100H)

Assume that the content of A is $A7 and that the content of B is $20. Find the contents of A and B after the MUL instruction is executed. [Hint: The MUL instruction assumes that the contents of A and B are unsigned integer values.]

1. Write down 2- differences between  Von-Neumann and Harvard architecture. 2. you are executing an instruction, SUB $s0, $s1, $s2 (address 0x20). Draw the datapath of this instruction when $s1=10, $s2=5. When are the stages in this datapath? Mark the components which are active in corresponding stages. 3. How to store(1050000)10 in register $s0? Write down the instructions that stores the data in $s0 register.

What other options are there besides OUTPUT for the pinmode instruction?
