Chapter 1: Von Neumann Architecture: This chapter introduces the foundational Von Neumann architecture, detailing its core components: the central processing unit (CPU), central memory (including RAM and ROM), and input/output (I/O) devices. It thoroughly explains the interaction between these components, emphasizing the crucial role of the bus system in data transfer and control. The chapter also delves into the characteristics of memory, including addressing, operations, and register functionalities (RIM and RAM registers), providing a solid base for understanding subsequent chapters on machine and assembly languages.
Chapter 2: Machine Language: This chapter focuses on machine language, the lowest-level programming language understood directly by the computer's hardware. It explores different execution models (memory-to-memory, memory-accumulator, register-register, and stack-based), contrasting their efficiency and complexity. The chapter systematically analyzes various instruction formats (with and without address fields, fixed vs. variable length) and addressing modes (immediate, direct, indirect), demonstrating their impact on instruction size and execution speed. Finally, it examines the design approaches of CISC and RISC processors.
Chapter 3: Assembly Language: This chapter transitions from machine language to assembly language, a more human-readable representation of machine instructions. It classifies programming languages (internal machine language, assembly language, high-level languages) and then focuses on a subset of the Intel 8086 assembler. The chapter meticulously covers the instruction set, including transfer, arithmetic, logical, shift, comparison, control flow, increment/decrement, I/O, interrupt, and address transfer instructions, providing detailed explanations and illustrating their usage through examples. This chapter bridges the gap between low-level hardware and higher-level programming paradigms.
Chapter 4: Combinational Logic Blocks: This chapter explores combinational logic circuits, which produce outputs based solely on current inputs, without memory of past inputs. It covers fundamental logic gates, Boolean function flowcharts, and crucial arithmetic circuits such as half and full adders and subtractors. The chapter also delves into encoding and decoding techniques, including decoders, encoders, and BCD to 7-segment decoders. Finally, it discusses multiplexers (MUX) and demultiplexers (DEMUX) and parity generators, providing examples and practical applications of these circuits.
Chapter 5: Sequential Logic Blocks: This chapter examines sequential logic circuits, which have memory and whose outputs depend on both current and past inputs. It covers various types of flip-flops (D, T, R-S, J-K) and their implementations. The chapter then discusses registers (including shift registers and their applications) and counters (asynchronous and synchronous), explaining their functionality and providing examples of their usage in computer systems. The content builds upon the foundation laid in the preceding chapters on logic gates and combinational logic.
