Study Notes
Computer Architecture and Organization
- Computer architecture focuses on high-level design aspects, like processor organization, memory hierarchy, input/output systems, and communication channels.
- Computer organization focuses on low-level design, such as the logical circuit design of the processor, memory organization, peripheral devices, and the data path of the computer.
- Programmers primarily interact with computer architecture, focusing on instructions visible to them. They are not concerned with the low-level implementation details.
Computer Architecture Categorizations
- By Number of Instructions per Clock Cycle:
- Von Neumann Machines: Execute one instruction at a time. Include:
- CISC (Complex Instruction Set Computer):
- RISC (Reduced Instruction Set Computer):
- MISC (Minimal Instruction Set Computer):
- TTA (Transport Triggered Architecture):
- DSP (Digital Signal Processor):
- Other Architectures:
- Accumulator Machines:
- Register Machines:
- Stack Machines:
- Very Long Instruction Word (VLIW) and Super-Scalar: Execute multiple instructions per clock cycle.
- Von Neumann Machines: Execute one instruction at a time. Include:
- Based on Connections between CPU and Main Memory:
- Princeton Machines: Use unified memory where a single address corresponds to both data and instructions.
- Based on Memory Spaces:
- Harvard Machines: Utilize separate memories for data and instructions, allowing simultaneous fetching.
Harvard Architecture
- Key Characteristic: Separate memories for data and instructions.
- Advantages: Allows the CPU to fetch instructions and data simultaneously, improving performance.
Von Neumann Architecture
- Key Characteristic: Single shared memory for both data and instructions.
- Advantages: Simplified design, as the CPU fetches both data and instructions from the same location.
- Disadvantages: Can lead to performance bottlenecks if the CPU needs to access both data and instructions concurrently.
ARM Architecture
- Common Use: Mobile devices and embedded systems.
- Focus Areas: Power consumption optimization and good performance.
