You are a homeowner and you have decided to invest some time into developing a temperature control system in your house instead of paying someone to do this work. You have available to you a microcontroller of your choice a well developed Kernel and your task is to write software to perform the temperature measurements and adjust the temperature accordingly. Provide a list of tasks you would need to realize your project (you can consider interrupts service routines to be tasks as well). Note:You do not have to write any code to solve this problem, but you must list the tasks you will need and draw a block diagramof the software system (show the states you could operate in and how your tasks can get into and out of those states. (Use the ideas used in the mC/OS-II or mCOS).

1. Write MIPS assembly code to sum “n” positive integers. For example, n=5, read 5 numbers in memory (“.data” section) and add them together.
2. Write MIPS assembly code to calculate N-factorial. Read n from the memory. (Hint: use “.data” to define the content in a memory location)

Single molecule devices are attractive to certain applications where small size and high capacity are both desirable. In terms of electrical conductivity capacity, most people would thick metal is the best and carbon based materials would be bad; is it true (or) not?
Provide an example to proof your argument.

Design Task 2: One Second Prescalar In many systems it is desirable to have a very fast system clock to clock most of the sequential entities in the system. However, there may be other sequential entities in the same system that need to be clocked at a much slower speed. An approach that allows flexibility in generating a slower clock frequency is a frequency divider, also called a prescalar. This is basically a counter that generates a pulse every n cycles of its input clock. The output occurs as a pulse with a frequency that is 1/n of the input clock frequency. However, the output pulse has a fixed duration that is one clk period long. 4 The prescalar to be designed is named one_sec_prescalar. If its cnt_en input is asserted at a rate of 32.768 kHz it must generate an output pulse every second. So, this design divides down it input by 32768. The input pulse is one system clock in duration and output pulse is one system clock in duration. This entity must also generate an output named one_hz that is a 1Hz square wave. The entity declaration for the one second prescalar is:
entity one_sec_prescalar is port( clk : in std_logic; -- system clock
rst_n : in std_logic; -- active low synchronous reset
clr_n : in std_logic; -- synchronous clear
cnt_en : in std_logic; -- count enable
one_hz : out std_logic; -- one Hz square wave output
one_sec_tick : out std_logic -- one clock wide pulse every sec );

How are the memory requirements for the real-time digital signal processing system affected by the sampling frequency, f s ? For example, if f s is increased by a factor of 2, what affect does this have on the system memory requirements?

(a) What is a high impedance relay and when is it used?
(b) A motor with differential protection has a full load current of 200 A. When starting, the motor takes 5 × FL current. The motor is remote from the switchgear which houses one set of CTs and the relay. If the CT ratios are 200/1, the secondary winding resistance is 1.0 ohm and the protection loop lead resistance to the motor is 6 ohms, calculate the minimum relay setting voltage. State what the CT knee point voltage should be.
