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.

Question

The processes A, B, C, and D are arrived to a system as shown in the table below. If the
scheduling mechanism is the Shortest Remaining Time First, what is the average waiting

Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Sensors (S1S2) Devices (DID2) 00 01 01 10 10 11 11 00 Write a program to control these two devices according to the values of sensors.
This question is on Process Synchronization in Operating Systems. You need to read the following scenario and find out which Process Synchronization method it resembles with. There are 3 washrooms for men and one for women. Only one person can enter a restroom at a time. When a person leaves the washroom, another person is allowed to enter the washroom. When they are not using the washroom, they are not doing anything. Men are not allowed to use the female washroom. So on a fine rainy day, 9 men arrived and 3 men were allowed to enter the 3 washrooms at a time. They were not allowed to use the female washroom even though it was vacant. What Process Synchronization method has been used here? A) Producer-Consumer B) Readers-Writers C) Dining Philosophers

Suppose we're modelling an RC crane which is receiving a sequence of input commands, each of which is UP, DOWN, or BEEP. This crane has only two vertical positions, and starts in the high position. It should go into an ERROR end state if it is asked to go UP when it is in the high position or DOWN when it is in the low position. Once it is in the ERROR state, it stays in the ERROR state no matter what commands it receives. BEEP commands are legal at any point. Give a state diagram for this system, in which each edge corresponds to receiving a single command.
In many races competitors wear a RFID tag on their shoes or bibs. When the racer crosses a sensor a computer logs the racer’s number along with the current time. Sensors can be placed along the course to accurately calculate the racer’s finish time or pace and also to verify that the racer crossed key checkpoints. Consider such a system in use for a half-marathon running race, which is 13.1 miles. In this problem there are only three sensors: at the start, at the 7-mile point, and at the finish line.Here is sample data for three racers. The first line is the gun time in the 24-hour time format (HH MM SS). The gun time is when the race begins. Subsequent lines are recorded by sensors and contain the sensor ID (0=start, 1=midpoint, 2=finish) followed by the racer’s number followed by the time stamp. The start time may be different than the gun time because sometimes it takes a racer a little while to get to the starting line when there is a large pack. 08 00 000,100,08 00 000,132,08 00…

The process shown in figure 1 involves pumping fluid from Tank A to Tank B. The operation of the process can be described as follows, Before starting, PS1 must be closed. When the start button is pushed, the pump starts. The button can then be released and the pump continues to operate. When the stop button is pushed, the pump stops. PS2 and PS3 must be closed 8s after the pump starts. If either PS2 or PS3 opens, the pump will shutoff and will not be able to start again for another 15 s. For the above mentioned conditions develop a ladder program using direct method and provide the allocation list. PS1 PS2 PS3 Tank Tank Pump Figure 1 B.
