Question

How many assumptions have to meet for a rate monotonic scheduling?

(a) 3

(b) 4

(c) 5

(d) 6

I got this question in a job interview.

My query is from Periodic Scheduling in chapter Embedded Operating System, Middleware and Scheduling of Embedded Systems

Answer 1

Right choice is (d) 6

Easiest explanation: The rate monotonic scheduling has to meet six assumptions. These are: All the tasks should be periodic,  all the tasks must be independent, the deadline should be equal to the period for all tasks, the execution time must be constant, the time required for the context switching must be negligible, it should hold the accumulation utilization equation.
