Study Notes
Computer Architecture
-
Instruction Set Architecture (ISA):
- Defines the syntax and semantics of assembly language
- Specifies the format of instructions, registers, and memory access
- Examples: x86, ARM, MIPS
-
Microarchitecture:
- Implementations of ISA in hardware
- Includes pipelining, branch prediction, and cache memory
- Affects performance, power consumption, and cost
-
Memory Hierarchy:
- Levels of memory organization: registers, cache, main memory, secondary storage
- Optimizes data access and reduces memory latency
- Cache memory: small, fast, and close to the processor
Programming
-
Programming Paradigms:
- ** Imperative**: focuses on procedures and steps (C, Java)
- Object-Oriented: organizes code into objects and classes (C++, Python)
- Functional: emphasizes pure functions and immutability (Haskell, Lisp)
-
Programming Languages:
- Low-Level: assembly language, machine language
- High-Level: C, C++, Java, Python
- Scripting: Python, Ruby, PHP
-
Algorithms and Data Structures:
- Algorithms: step-by-step procedures for solving problems (sorting, searching)
- Data Structures: formats for organizing and storing data (arrays, linked lists, trees)

-
Microarchitecture
- Implements ISA in hardware
- Includes pipelining, branch prediction, and cache memory
- Affects performance, power consumption, and cost
-
Memory Hierarchy
- Registers: small, fast, and built into the processor
- Cache: small, fast, and close to the processor
- Main memory: larger, slower, and further from the processor
- Secondary storage: largest, slowest, and furthest from the processor
Programming
-
Programming Paradigms
- Imperative: focuses on procedures and steps, altering state and variables
- Object-Oriented: organizes code into objects and classes, with inheritance and polymorphism
- Functional: emphasizes pure functions, immutability, and recursion
-
Programming Languages
- Low-Level: closest to machine language, requires manual memory management
- High-Level: abstracts away low-level details, provides built-in memory management
- Scripting: focuses on rapid development, ease of use, and high-level abstractions
-
Algorithms and Data Structures
- Algorithms: step-by-step procedures for solving specific problems (e.g., sorting, searching)
- Data Structures: formats for organizing and storing data, with trade-offs in access time and space (e.g., arrays, linked lists, trees)
Test your knowledge of computer architecture, including instruction set architecture, microarchitecture, and memory hierarchy, and their impact on performance and power consumption.
