Control Flow Instructions: Branches and Jumps

In this section, the video discusses control flow instructions, focusing on branches and jumps that allow altering the sequence of executing instructions.

Conditional and Unconditional Branches

• Conditional branches are known as branch and risk five, while unconditional branches are called jump.

• Four flavors of conditional branches include branch on equal, branch on not equal, branch of less than, and branch of greater than.

• These branches compare two sources and determine whether to take the branch based on their relative values.

Conditional Branch Example

• An example demonstrates a program using conditional branches:

• Program executes operations like adding immediate values to registers and shifting bits left logically.

• A branch on equal compares register values; if they match, it takes the branch to a specified label for further execution.

Unconditional Jump Example

• An unconditional jump example is provided:

• Replacing the conditional branch with an unconditional jump alters program flow.

• The program continues executing without branching based on register comparison results.
