The critical interface between software and hardware. It defines the native commands (like ADD , MOVE , or JUMP ) that the processor can understand and execute.
Instruction Set Architecture (ISA), data types, and addressing modes. Control signals, memory technology, and bus structures. The architectural blueprint of a house. COMPUTER ORGANIZATION AND ARCHITECTURE
Focuses on rich, complex instructions that can perform multi-step operations in a single command, prioritizing smaller code sizes (e.g., x86). The critical interface between software and hardware
Focuses on simple, highly optimized instructions that execute in a single clock cycle, prioritizing speed and efficient hardware pipelines (e.g., ARM). COMPUTER ORGANIZATION AND ARCHITECTURE and addressing modes. Control signals
Computer architecture defines the attributes of a system that are visible to a programmer and have a direct impact on the logical execution of a program.
