Explain the concept of masking interrupts. Discuss different masking mechanisms and how they can affect the execution of a program. Describe difficulties you might encounter when developing an embedded real-time applications using Java as the development programming language. Also, describe advantages of using Java for such applications. Sometimes embedded systems need real-time performance. Explain how a RISC processor like the ARM can help in guaranteeing such performance predictably (hint: think about how RISC processors execute instructions). (DIFFICULT QUESTION FOR
