M4 Flashcards
refers to those attributes of a system visible to a programmer.
Computer architecture
refers to those attributes that have a direct impact on the logical
execution of a program.
Computer architecture
refers to the operational units and their interconnection that
realize the architecture specification.
Computer organization
is the way in which the components are interrelated.
Structure
is the operation of each individual component as part of the structure.
Function
controls the operation of the computer and performs its data processing functions.
CPU
Some mechanism that provides for communication among CPU,
main memory, and I/O.
System Interconnection.
controls the operation of the CPU and hence the computer
Control Unit
performs computer’s data processing functions
ALU
provides storage internal to the CPU.
Register
Some mechanism that provides for communication among the
control unit, ALU, and register.
CPU Interconnection.
is the electrically conducting path along which data is transmitted inside any digital
electronic device.
Bus
allows data to travel back and forth between the microprocessor (CPU) and
memory (RAM).
Data bus
The 80x86 processors use this bus to shuffle data between the various
components in a computer system.
Data bus.
specifies the location of data in memory.
Address bus
is an extensive collection of signals that control how the processor
communicates with the rest of the system.
Control bus
control the direction of data on the data bus.
Read and write control lines
allow 16, 32, and 64 bit processors to deal with smaller
chunks of data.
Byte enable lines control lines
is used to select the desired memory or I/O devices by providing a unique
address that corresponds to one of the memory or I/O.
Address bus
is used to carry control signals to and from the memory or I/O devices. It is
bi-directional.
Control bus
Many computer manufacturers offer a family of computer model, all with the same
X but with differences in organization.
architecture
An X may survive many years, but its X changes with changing
technology.
architecture
organization
is a set of interrelated subsystem
A hierarchical system
is essential to both their design and their
description.
The hierarchical nature of complex systems
