Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain computer architecture and its levels and design principles, describe major architecture families and trends, support learning and design questions, and describe history and current developments.

The design of the structure and organisation of computer systems, covering instruction set architecture that defines what programs see, microarchitecture that implements it, and system organisation of processors, memory, storage and interconnects, in families such as von Neumann and Harvard designs, reduced and complex instruction sets, dataflow architectures, massively parallel and domain-specific architectures for graphics and machine learning; computer architecture balances performance, power, cost and compatibility.

What it is for: Design of computer system structure.

It can be explain levels and principles; describe architecture families; support learning and design; describe trends.

Distinguishing features

Compatibility

What it looks like

Not physical; designs realised in hardware.

How it is recognised

Structure and organisation of computers

Instruction set, microarchitecture, system organisation

Computer engineering builds the hardware; software architecture concerns programs
