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

Let us assume that we would like to design an ISA R-format instruction format for a processor. The processor has 256 registers and 64 opcodes. The R-format has four fields, the opcode and three fields for the registers. Show the instruction format and the bit allocation for each field.
