2. (40 pts) For the simple computer developed in class, assume it is now word-addressable (NOT byte addressable). Consider the following program starting in memory location 0. 0000000000001010 0010000000000100 0000000000001010 0010000000000101 0010000000000011 0001000000000000 Assume the contents of locations 10, 12, 14 are 4, 6, 8, respectively. The content of AC is zero before the program is executed. 1) Translate each memory line in the above program into an assembly instruction (e.g., with opcode ADD or JMP). For example, the first instruction can be written as ADD 0b1010 or ADD 10. (10 pts) % 2) Write down the execution sequence of those instructions. Note that JMP can change the execution sequence. No need to write any microinstructions. (10 pts). 3) What will be the content of AC in two cases: (a) before the first execution of the last instruction (i.e., the last line in the above program: 0001000000000000) and (b) after the execution of the entire program?
