5.3 Instruction Set Architecture (P3)

Question 1

What does control flow refer to

Answer 1

Question 2

What does explicit control flow look like in the fetch decode execute cycle of a program (setting PC to target)

Answer 2

Question 3

What is an absolute vs relative branch (control flow)

Answer 3

Note for relative, PC is already incremented so x should be -1 than seems

Question 4

What is an unconditional vs conditional branch (control flow)

Answer 4

Question 5

What is the difference between compare-plus-branch and compare-then-branch (conditional explicit control flow)

Answer 5

Question 6

What are 3 different data-sources / ways of comparing values in a conditional branch (control flow)

Answer 6

Question 7

What is the difference between an immediate and computed branch (control flow)

Answer 7

Immediate is limited to size of operand, computed is not

Question 9

What is branch and link in control flow (can be used for functions)

Answer 9

Answer 11

Question 12

What does a for loop look like using instructions
