Question:

What is the address of the exception handler in 4.25.3? What happens if there is an invalid instruction at that address in instruction memory?

Exercise 4.25.3

If the second instruction from this table is fetched right after the instruction from the first table, describe what happens in the pipeline when the first instruction causes the first exception you listed in 4.25.1. Show the pipeline execution diagram from the time the first instruction is fetched until the time the first instruction of the exception handler is completed.

Exercise 4.25.1

Which exceptions can each of these instructions trigger? For each of these exceptions, specify the pipeline stage in which it is detected.


The remaining three problems in this exercise assume that exception handlers are located at the following addresses:Overflow a. 0x1000CB05 b. 0x450064E8 Invalid Data Address Ox1000D230 OXC8203E20 Undefined Invalid Instruction
