- Consider a HW ISA program P1 with the following Instruction Memory IM: a. fill in the execution table for program P1 using the IM. Use the same notational conventions used in the example execution table for P0 below. Any numbers beginning with 0x will be interpreted as hexidecimal; any numbers not beginning with 0x will be interpreted as decimal. b. Show the final values of the registers R2, R3, and R4 when the program execution halts. Again, any numbers beginning with 0x will be interpreted as hexidecimal; any numbers not beginning with 0x will be interpreted as decimal.Task#1: Assembly Language Programming: Write down the states of RAM and registers, in line by line Debugging Mode, in the following given scenarios.
