Computer architecture¶
Datapaths, control, instruction sets, x86-64 execution, privilege, caches, memory hierarchy, buses, MMIO and DMA.
Scope¶
This volume defines the terminology and relationships required before implementation detail. General concepts remain separate from ChrisOS-specific decisions; when a chapter crosses into implementation, its source revision and relevant files are declared in frontmatter.
Core chapters¶
- CPU datapath and ISA
- x86-64 memory and privilege
- Buses, MMIO and DMA
Reading rule¶
Lower-layer details need not be memorized, but terms used by higher layers are defined before their first technical use. Diagrams show flow and responsibility; tables record contracts, layouts and states.
