William stallings computer organization and architecture 6th edition - Chapter 1: Introduction

William Stallings Computer Organization and Architecture6th EditionChapter 1IntroductionArchitecture & Organization 1Architecture is those attributes visible to the programmerInstruction set, number of bits used for data representation, I/O mechanisms, addressing techniques.e.g. Is there a multiply instruction?Organization is how features are implementedControl signals, interfaces, memory technology.e.g. Is there a hardware multiply unit or is it done by repeated addition?Architecture & Organization 2All Intel x86 family share the same basic architectureThe IBM System/370 family share the same basic architectureThis gives code compatibilityAt least backwardsOrganization differs between different versionsStructure & FunctionStructure is the way in which components relate to each otherFunction is the operation of individual components as part of the structureFunctionAll computer functions are:Data processingData storageData movementControlFunctional viewOperations (1) Data movementOperations (2) Storage Operation (3) Processing from/to storage Operation (4)Processing from storage to I/OStructure - Top LevelComputerMain MemoryInputOutputSystemsInterconnectionPeripheralsCommunicationlinesCentralProcessing UnitComputerStructure - The CPUComputerArithmeticand Login UnitControlUnitInternal CPUInterconnectionRegistersCPUI/OMemorySystemBusCPUStructure - The Control UnitCPUControlMemoryControl Unit Registers and DecodersSequencingLoginControlUnitALURegistersInternalBusControl UnitOutline of the Book (1)Computer Evolution and PerformanceComputer Interconnection StructuresInternal MemoryExternal MemoryInput/OutputOperating Systems SupportComputer ArithmeticInstruction SetsOutline of the Book (2)CPU Structure and FunctionReduced Instruction Set ComputersSuperscalar ProcessorsControl Unit OperationMicroprogrammed ControlMultiprocessors and Vector ProcessingDigital Logic (Appendix)Internet Resources- Web site for book to sites of interestlinks to sites for courses that use the bookerrata list for bookinformation on other books by W.
