You are tasked with designing an ICS/SCADA system. You must choose a type of ICS/SCADA system from the options listed below:

Correctional facility

Paint processing plant

Water distribution facility

Considering the type of system you chose from the list above, discuss the model you would use (time or event-based or a combination) and for what purposes. What considerations do you need to take into account in your design? How does the PLC fit into this system?

how do you know your product is a good one and how do you sell the idea to an investor?

V. How does ARM processor differentiate between a timer interrupt and an A/D interrupt?

VI. What does privileged mode mean and what is the major difference between this mode and non-privileged mode?

VII. There are two interrupt pins on ARM microprocessor: IRQ and FIQ. Which one can interrupt the other one and why?

DO IT To receive credit for this assignment, each problem must be computed using a MATLAB script. Do not hard-code computations. Define variables for the parameters given in the problem, and use MATLAB to calculate necessary intermediate and final output variables. Inlcude the MATLAB Code. A 200-mi. transmission line has the following parameters at 60 Hz: Resistance, r = 0.24 Ω/mi. per phase Series Reactance, x = 0.71 Ω/mi. per phase Shunt Susceptance, b = 5.42 × 10−6 S/mi. per phase Determine the signal wavelength λ and the propagation constant γ, attenuation constant α, phase constant β, and characteristic impedance Zc of the transmission line at 60 Hz using the general expressions in terms of Z and Y parameters valid for conductance G = 0 S/mi. Next, calculate the “convenient” artificial value for conductance G = RC/L and α, β, and Zc using this approximation. Finally, determine the sending-end voltage and current if the line is open-circuited and the receiving-end voltage is 100 kV line-to-line.

VHDL Code: Design a 16-bit 4-to-1 multiplexer using data-flow implementation style. Data inputs and output should be 16-bit vectors. In your test bench, you should include enough number of test cases to show the correctness of your design.

Pin=0.1 W, G1=400, L=2,000, G2=500

VLSI circuit design

integrated ciruit : fabrication and manufacturing in industry

imulate/ code in verilog:

Develop an electronic key system using the FSM (moore) methology. Use from student ID and use the last 4 digits:(0864)

if the number is <5 then = 1

if the number is >=5 then = 0

example: 8012345. Take last 4 digits (2345) which makes it 0001.

In my case, the last 4 digits are 0864, which makes it 0110

features of FSM (moore FSM):

input 4 bits serially,

if the sequence is correct, then you proceed to next state. Otherwise, go to error state, then go to rest state

13.3 Expand on Start-Up Testing , ie: when and what would you expect to be doing / checking.

Assignment Instructions:

1) The Factorial

The factorial of a non-negative integer ??, denoted by ??!, is the product of all positive integers less than or equal to ??. The textbook has an example of a recursive MIPS implementation of factorial. Additionally, a simplified version of the MIPS assembly language recursive implementation of the factorial function is attached. Trace the factorial example carefully using QTSPIM

2) Recursive definition of multiplication

The function ??????????(??, ??) for two positive integers 1 ? ??, and 1 ? ??, is defined as the following:

??????????(??, 1) = ??; ??????????(??, ??) = ?? + ??????????(??, ?? ? 1)

Write a recursive version of ??????????() in C or C++ and a pseudo C program (based on chapter 2 in the book) then use these programs to develop a MIPS program that gets as input two integers 0 < ?? ? 255, and 0 < ?? ? 255, and returns the result of ??????????(??, ??) in $v1.

Your deliverable should be the pseudo C and the assembly level function
