Problem Overview The project will simulate a simple computer system consisting ofa CPU and Memory. The CPU and Memory will be simulated by separate processes that communicate Memory will contain one program that the CPU will execute and then the simulation will end. Objectives arm how multiple posses mportnt to an operating sys svtstem calls 1) 2) Learn how multiple processes can communicate and cooperate. Understand low-level concepts important to an operating system. a. b. c. d. e. f. System calls. g. Interrupt handling Processor interaction with main memory Processor instruction behavior. Role of registers. Stack processing. Procedure calls. b. Processor instruction beni Memory protection. i. IO.
