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
Dictates how numbers, characters, and logical values are encoded as binary digits within the hardware. Predominant Design Philosophies:
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
The critical interface between software and hardware. It defines the native commands (like ADD , MOVE , or JUMP ) that the processor can understand and execute.
Focuses on rich, complex instructions that can perform multi-step operations in a single command, prioritizing smaller code sizes (e.g., x86). Control signals, memory technology, and bus structures
The techniques specified in the ISA to determine where the data operands for an instruction are located (e.g., in registers or main memory).
The actual bricks, cement, and electrical wiring used to build it. 🛠️ 2. Core Components of Computer Architecture It defines the native commands (like ADD ,
The distinction between these two concepts is fundamental to understanding modern computing systems. Computer Architecture Computer Organization High-level system design and behavior. Low-level physical components and interconnections. Visibility Directly visible to the assembly programmer. Transparent/hidden from the programmer. Core Elements
