Study Notes
Computer Abstractions and Technology
- Post-PC era: Personal mobile devices (PMDs) and tablets replace desktops, Cloud computing and warehouse-scale computers (WSCs) replace traditional servers.
- Understanding hardware/software interface is critical for writing software and improving program performance.
- Program performance depends on the original program, software translation, and hardware effectiveness.
- Hardware designers improve performance through techniques like subword parallelism, instruction-level parallelism, memory hierarchy optimization, and thread-level parallelism.
- Energy efficiency is a crucial design concern, requiring consideration by both hardware designers and programmers.
- Multicore microprocessors (multiple processors on a single chip) are replacing uniprocessors.
- Computer architects have developed foundational "great ideas".
- Software layers (applications, systems software, hardware) are hierarchical.
Hardware/Software Interface
- Systems software encompasses operating systems, compilers, loaders, and assemblers.
- Software translates high-level operations into simple computer instructions.
- Applications rely on sophisticated software libraries.
- Hardware executes primitive low-level instructions. -
- Embedded processors outnumber PC processors.
Performance Evaluation
- Performance depends on many factors beyond speed.
- Cost, power, reliability, scalability are important.
- Balancing these factors is key for optimal design.
- Program performance depends on factors like programming language, compiler, computer architecture, processor/memory system, and I/O system.
Integrated Circuits (Chips)
- Integrated circuits (ICs) combine many transistors on a single chip.
- Chips are the foundation of modern computing technology, driving cost/performance improvements.
- The microprocessor (CPU) is the active component of a computer, following program instructions.
Dependability
- Redundancy is crucial for dependability in computer systems.
- Redundant components for fail-over and failure detection is necessary since physical devices can fail, ensuring systems work as reliably as possible.
Memory Hierarchy
- The memory hierarchy is represented by a layered triangle.
- Layers closer to the top are faster, more expensive per bit.
- Wider layers mean larger memory capacity.
Abstraction
- Abstraction is a key concept, involving increasingly complex applications relying on sophisticated software libraries interpreted/translated into simple instructions.
