16. Handling Control Transfer Instructions
The chapter extensively discusses control transfer instructions essential in computer architecture. It differentiates between conditional and unconditional jumps, outlining how these instructions utilize control signals and microinstructions during execution. The chapter further highlights the steps involved in processing these instructions, emphasizing the importance of storing the current value of the program counter in a temporary register for accurate execution.

What we have learnt
- Control transfer instructions are classified into conditional and unconditional jumps.
- Execution of jump instructions involves additional steps compared to regular instructions due to the need to manage the program counter.
- The architecture employs temporary registers to store critical values during the execution of jump instructions.
Key Concepts
- -- Control Transfer Instructions
- Instructions that alter the flow of execution in a program, typically categorized as unconditional or conditional jumps.
- -- Program Counter (PC)
- A special register that contains the address of the next instruction to be executed.
- -- Offset
- A value calculated from the current program counter that determines the target address for jump instructions.
