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.

4. (a) What is instruction byte queue? What is its advantage?
(b) Explain the concept of memory segmentation. How is the address
of the locations of program bytes generated?
5. Define Interrupt. Distinguish between vectored interrupts and non-
vectored interrupts. Explain the function of SIM and RIM.
6. Explain the difference between the status check I/O and Interrupt I/O
in case of 8255 A for Input in Mode 1?
7. A set of 10 signed data bytes is available in memory starting at 3050H.
Write a program to identify the negative numbers. The positive
