MGMT 1050 Chapter 10 Notes – Summary
Introduction
CPU architectures
• Will to help you create a new career as an assembly language programmer or computer
hardware engineer.
• These at least introduce you to the major concepts, methods, and terminology used in
modern computers.
• When reading, remember to keep your focus on the larger picture.
• The details are just variations on a theme.
• CPU architecture is defined by the basic characteristics and major features of the CPU.
• CPU architecture is sometimes called instruction set architecture (ISA).
• These characteristics include such things as the number and types of registers, methods
of addressing memory, and basic design and layout of the instruction set.
• It does not include consideration of the implementation, instruction execution speed,
details of the interface between the CPU and associated computer circuitry, and various
optional features.
• These details are usually referred to as the coputer’s orgaizatio.
• The architecture may or may not include the absence or presence of particular
instructions, the amount of addressable memory, or the data widths that are routinely
processed by the CPU.
• Some architecture is more tightly defined than others.
• These ideas about computer architecture should not surprise you.
• Consider house architecture.
• A split-level ranch house, for example, is easily recognized by its general characteristics.
• Even though there may be wide differences in features, internal organization, and
design from one split-level ranch to the next.
