Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.

SFJ Process Suppose we have a four (4) core processor and all processes are designed to be multi-threaded. Now, like all processors with more than one core, they have the ability to perform multiple tasks at the same time. If there are four (4) with the following CPU and I/O cycles according to the table below, calculate the times for the SJF scheduling process (view image): Where A,B,C,D correspond to A=6, B=3, C=5, D=8.

A CPU has a frequency of 2GHz and can execute code with three types of instructions: 1. Type 1 instructions require 1 cycle to finish. 2. Type 2 instructions require 4 cycles to finish. 3. Type 3 instructions require 10 cycles to finish. For each combination of instruction types below, estimate the total number of instructions executed in 1 second. Select the closest choice (round to the nearest). Note, the percentages indicate the number of instructions of each type in the executed code.

Consider a real-time system in which there are four tasks. Their period and execution time are as follows
We have 4 periodical processes II₁, II, II and II, that process a video. We know their periods P; and their running times C; (in milliseconds). For: (a) the rate monotonic scheduling (RMS) algorithm and (b) the earliest deadline first (EDF) algorithm draw diagrams that displays the schedule for those processes for a period of 150 ms. The times are the following: Process Pi Ci II₁ 45 10 II2 40 10 II3 35 5 II4 50 10 In the case of equal priorities the process that is already running has the priority. If this is not the case then take the process with the lowest ID. Does any of the above algorithms fail?
Create a UML State Machine Diagram for the following description of an Engine Control Unit: The ECU generally starts in the state “off.” Once the engine is started, the engine control unit powers up as well. While the ECU is fully powered up, it is usually in idle mode, delivering the minimally necessary fuel with a lean air/fuel mixture to the engine, and igniting appropriately. As soon as the driver presses the gas pedal, the ECU calculates the necessary torque. To do so, it first checks the new gas pedal position, then as long as the gas pedal position remains the same, calculates the necessary air and fuel supply as well as the ignition point. As soon as these values are computed, the ECU does three things simultaneously: it checks if the air and fuel amount currently supplied to the engine is still appropriate. If more or less fuel or air is needed, the ECU will assume the adequate operation mode of “less fuel” or “more air,” etc. The third thing the ECU does is to check if the…

CPU scheduler will decide which process should be given the CPU for its execution. For this it uses different algorithm to choose among the process. One among that Algorithm is Priority algorithm. In this algorithm the processes will be given the priorities. The process which is having the highest priority is allocated the cup first. After finishing the request, the CPU is allocated to the next highest priority and soon. Write an algorithm and C program for the Priority algorithm.

A common variable x, introduced to nothing, is worked on by four simultaneous cycles W, X, Y, Z as follows. Every one of the cycles W and X peruses x from memory, increases by one, stores it to memory, and afterward ends. Every one of the cycles Y and Z peruses x from memory, decrements by two, stores it to memory, and afterward ends. Each cycle prior to perusing x summons the P activity (i.e., look out) on an including semaphore S and conjures the V activity (i.e., signal) on the semaphore S in the wake of putting away x to memory. Semaphore S is introduced to two. What is the most extreme conceivable worth of x after all cycles total execution?
