Discussion
Consider the following statements about a real time kernel.
1. Every task needs its own stack 2. A handler may block on a kernel object 3. Tickless operation saves power when the system is idle
Answer: D
Correct answer: 1 and 3 only are correct
Statements 1 and 3 are correct: each task has its own stack, since each has its own call chain, and tickless operation lets the processor sleep through idle periods instead of waking at every tick. Statement 2 is exactly what a handler may not do, there being no task context to block.
