Comprehensive computer organization and architecture diagram mapping CPU components (Control Unit, ALU, Registers) through system buses to memory hierarchy and I/O controllers. Data flows from CPU registers through multi-level cache (L1, L2, L3) to main RAM via data, address, and control buses, connecting to secondary storage and I/O devices. Architecture layer details instruction set architecture (ISA), addressing modes, instruction formats, pipeline stages, and performance metrics (CPI, IPC, clock cycles) essential for understanding processor design. Fork this diagram on Diagrams.so to customize for specific ISA implementations (x86, ARM, RISC-V), add microarchitecture details, or create educational materials. Perfect reference for computer architecture courses covering von Neumann architecture, memory hierarchy, and instruction-level parallelism.
