Lesson 2 • FSM Verification and Simulation

Validates FSM behavior through timing diagram simulation and state-transition testing. Confirms correct operation before hardware implementation.

Lesson 3 • State Encoding Strategies

Compares binary, Gray, one-hot, and output-encoded assignment strategies. Encoding choice directly affects next-state logic complexity and timing performance.

Translates word descriptions into state diagrams and tabular state tables. Establishes the formal FSM model that drives all subsequent sequential design steps.

Lesson 1 • Sequence Detectors and Generators

Implements shift-register-based sequence detectors and pseudo-random sequence generators. Applies FSM and shift register knowledge to pattern recognition tasks.

Lesson 2 • Shift Register Configurations

Covers SISO, SIPO, PISO, and PIPO shift registers with serial and parallel modes. Connects shift operations to serial communication and data-conversion applications.

Lesson 3 • Synchronous Counter Design

Designs binary, BCD, and arbitrary-modulus synchronous counters using FSM methods. Reinforces state encoding and next-state logic from Chapter 4.

Lesson 4 • Ripple and Asynchronous Counters

Analyses ripple counter propagation delay and glitch behaviour. Contrasts asynchronous designs with synchronous alternatives to guide appropriate selection.

Lesson 1 • Division and Remainder Circuits

Covers restoring and non-restoring division algorithms and their hardware implementations. Completes the four-operation arithmetic set needed for a functional ALU.

Lesson 2 • Fixed-Point and BCD Arithmetic

Extends binary arithmetic to fixed-point fractions and BCD addition with decimal adjust. Addresses numeric formats used in embedded and financial computing systems.

Lesson 3 • Arithmetic Logic Unit Architecture

Integrates adder, logic, and shift functions into a parameterised ALU with opcode control. Applies multiplexer-based function selection from Chapter 2.

Lesson 4 • Fast Adder Architectures

Compares carry-lookahead, carry-select, and carry-save adder structures for speed. Builds on ripple-carry adders from Chapter 2 to achieve higher clock frequencies.

Lesson 1 • Dynamic RAM Principles

Explains DRAM cell charge storage, refresh requirements, and burst access modes. Contrasts DRAM density advantages against SRAM speed for system-level selection.

Lesson 2 • ROM Types and Logic Implementation

Covers mask ROM, PROM, EPROM, and EEPROM structures and their programming mechanisms. Shows how ROM implements combinational logic functions as lookup tables.

Lesson 3 • Memory Expansion and Interfacing

Expands word width and address depth using chip-select decoding and memory banking. Prepares students to integrate memory subsystems into complete digital designs.

Lesson 4 • Static RAM Design and Operation

Analyses the 6T SRAM cell, sense amplifiers, and read-write timing cycles. Provides the foundation for understanding cache memory in processor systems.

Lesson 1 • Functional Simulation and Test Benches

Creates structured test benches with directed and random stimulus to verify system behaviour. Establishes simulation discipline before committing to physical implementation.

Lesson 2 • Control Unit Implementation

Implements hardwired and microprogrammed control units that sequence data-path operations. Applies FSM design from Chapter 4 to generate control signals for the data path.

Lesson 3 • Top-Down System Partitioning

Decomposes complex system specifications into data-path and control-unit hierarchies. Applies structured design methodology to manage complexity in large circuits.

Lesson 4 • Data-Path Design and Integration

Assembles registers, ALU, multiplexers, and buses into a complete operational data path. Reinforces interconnection of all combinational and sequential blocks from prior chapters.
