1. 1 Homework 1.Imagine you are a RTOS developer. Your task is to implement preemptive OS. What hardware peripherals for task switching algorithm shall you take into account? What information of running process/task should be saved? Explain your choice. 2.Select some RTOS or OS-less variant for task:  Cell-phone billing system  Radio-based home automation system Prove your selection, what is the reason and important features? 3.Short overview for RTOS QNX Neutrino, VxWorks, WinCE, mITRON4.0, Micro/OS-II  Architecture  Supported platforms  Scheduling  Kernel features  Supported standards  Development tools Prepare a comparison table
