2 cards from this section. Quick, good the night before a test.
What is the purpose of the Program Counter in an unconditional jump?
Think about which register determines the sequence of instruction executions.
Define offset in the context of unconditional jumps.
Consider how we calculate where to go next in the instruction sequence.
What register holds the address of the next instruction to be executed?
Remember, it directs the flow of instruction execution.
True or False: The offset in a jump instruction is the direct address to which the execution jumps.
Consider how the address is derived.
Given a Program Counter at address 500 and an offset of 300, determine the new PC after an unconditional jump. What implications might this have in a relocatable program?
Just add the current PC and offset.
Analyze how the execution flow differs when a conditional jump is used instead of an unconditional jump. What additional steps are required?
Think about what must happen before jumping.
