The purpose of computer organization is to understand the operating mechanism of the computer, master the concrete composition of each component and the connection between them, and realize the function and characteristics of the machine instruction. This course includes the following aspects: the basic concept, principle, and design method of the overview of computer organization, system hardware structure, memory, input and output system, operation method, instruction set, CPU, control unit,. Through theoretical teaching and curriculum design, we can improve students' mastery and design ability of computer organization. Through the study, students can integrate the software and hardware knowledge learn in computer organization,compiler, assemble language and so on, then build a whole view on computer systems.
