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.

Computer Science - Assembly language code: Q1. A) A microprocessor is wired into a sensing control circuit so that the memory locations 42 and 43 each contain the values 0 or 1. Memory location 50 is connected to a light switch. When the value in 50 is 1 the light is on and when it is 0 the light is off. Write a program to switch on the light on when the values in locations 42 and 43 are both 1, and to switch off the light when the values in locations 42 and 43 are both 0. Only use the ARM assembly language instructions, MOV, JMP and JNZ. Assume that the MOV instruction updates the flags with the status register.
