Question

In which of the exceptions does the external event causes the exception?

(a) synchronous exception

(b) asynchronous exception

(c) precise

(d) imprecise

I got this question during an internship interview.

I need to ask this question from RISC Exceptions in division Interrupts and Exceptions of Embedded Systems

Answer 1

Correct answer is (b) asynchronous exception

Easiest explanation: The asynchronous exception is the one in which an external event causes an exception and is independent of the instruction flow. On the other hand, the synchronous exceptions are synchronised, that is, it is caused by the instruction flow.
