We also delve into data representation, including number systems (binary, decimal, hexadecimal), character encoding (ASCII, Unicode), and data structures. Understanding instruction sets (RISC vs. CISC) and the fundamental fetch-decode-execute cycle is essential here.
Chapter 2: CPU Design and Pipelining: The Central Processing Unit (CPU) is the brain of the computer. This chapter explores its internal architecture, focusing on components such as the Arithmetic Logic Unit (ALU), Control Unit (CU), registers, and cache. We delve into pipelining, a crucial technique for improving CPU performance by overlapping instruction execution stages. Different pipelining hazards (data hazards, control hazards) and their mitigation strategies are also discussed.
Chapter 3: Memory Systems: Efficient memory management is critical for optimal system performance. This chapter examines different types of memory, including RAM, ROM, and secondary storage. We explore cache memory hierarchies (L1, L2, L3 caches), their organization, and replacement algorithms. Virtual memory, a technique that allows the use of more memory than physically available, is also explained. The concept of memory mapping and its role in operating system functioning are discussed.
Chapter 4: Input/Output Systems: Input/Output (I/O) systems are responsible for communication between the computer and the outside world. This chapter covers different I/O devices, including keyboards, mice, displays, and storage devices. We explore interrupt handling, direct memory access (DMA), and various I/O architectures, such as programmed I/O, interrupt-driven I/O, and DMA-driven I/O. The trade-offs between these different methods are analyzed.
Chapter 5: Parallel and Multi-core Architectures: Modern computers rely heavily on parallel processing to increase performance. This chapter explores different parallel processing techniques, such as multithreading, multiprocessing, and SIMD (Single Instruction, Multiple Data). We analyze the architecture of multi-core processors, discussing their benefits and challenges, including cache coherence and synchronization. The use of GPUs for parallel processing, especially in areas like machine learning, is also considered.
