lAn embedded system is to be designed to run from battery power. The system must remain powered, but will have short periods of activity, separated by long periods of inactivity. i) Explain the impact of clock frequency on power consumption. (30%) ii) Describe in as much detail as you can features that you would expect to find on a power-conscious microcontroller, which can be used to minimise power consumption. (40%) iii) What other techniques of circuit design can be applied, to minimise power consumption
