This chapter presents the following content: Instruction fetch and execute, interrupts, i/o function, suggested reading: stallings chapter 3. | Chapter 02 Computer Organization and Architecture Top Level View of Computer Function and Interconnection 1 KEY POINTS The major computer system components (processor, main memory, I/O modules) need to be interconnected in order to exchange data and control signals. The most popular means of interconnection is the use of a shared system bus consisting of multiple lines. In contemporary systems, there typically is a hierarchy of buses to improve performance. Key design elements for buses include Arbitration (whether permission to send signals on bus lines is controlled centrally or in a distributed fashion); Timing (whether signals on the bus are synchronized to a central clock or are sent asynchronously based on the most recent transmission); And width (number of address lines and number of data lines). . Computer Components Virtually all contemporary computer designs are based on concepts developed by John von Neumann at the Institute for Advanced Studies,Princeton. Such a design
