Section B (Use a separate answer book for this Section) 2a i) Name one field that exists in every machine instruction. ii) Name three possible ways to address operands in an instruction? Which way is the most time efficient in execution? iii) A CPU has a "jump" instruction: JZ Ri, Address where the program will fetch the next instruction at memory location Address if register Ri is zero. By illustrating in a couple steps, explain how this instruction is executed. Name the registers involved in the execution. iv) A "call'" instruction starts the execution of a function or method. What is the main difference between a "jump" instruction and a "call" instruction? Explain how and why stack memory can be used to facilitate nested function calls.
