Abstract

In this paper a concept of an operating system nucleus is introduced and its synthesis is discussed. According to this concept the operating system nucleus should be realized as hardware that generates the operation code and address parts of the programs belonging to the OS-nucleus. Note that in the current OS-nucleus the same opcode appearing in different instructions is stored very many memory locations. In the presented solution each opcode appearing in very many instructions is represented by only one elementary memory element (e.g. by one flip-flop), included in the designed hardware. Similar reasoning concerns the addresses of operands. In this paper the synthesis of such type of the hardware by using graphs is considered and also its result in the form of the block diagram of this hardware is shown. Moreover, some advantages of the presented approach to new type of the OS-nucleus are discussed.
