Question

Which of the following systems are entirely controlled by the timer?

(a) voltage triggered

(b) time triggered

(c) aperiodic task scheduler

(d) periodic task scheduler

This question was addressed to me in an international level competition.

I'd like to ask this question from Classification of Scheduling Algorithms topic in chapter Embedded Operating System, Middleware and Scheduling of Embedded Systems

Answer 1

Correct answer is (b) time triggered

To explain I would say: The systems which are entirely controlled by a timer are known as entirely time-triggered systems. A temporal control structure is associated with the entirely time-triggered system which is encoded in a TDL, task descriptor list.
