Study-Unit Description


TITLE Computer Logic 2

UM LEVEL 01 - Year 1 in Modular Undergraduate Course



DEPARTMENT Communications and Computer Engineering

DESCRIPTION The fundamental topics in sequential logic are covered in this unit. The topics include the concept of state and transitions between different states. The study-unit also covers the use of sequential building blocks such as latches and flip-flops to design and implement systems such as shift registers and counters. These concepts are developed to include the design and implementation of finite state machines (FSMs).

The study-unit also provides an understanding of sequential arithmetic algorithms used in computer design. The control unit is also explored, and an overview of the different implementation techniques is given. Different memory technologies, such as SRAM and DRAM, are explored with attention to their different characteristics and their suitability for different applications.

Study-Unit Aims:

- To explain the nature of state machines;
- To explain the design of sequential logic systems and state machines;
- To explain the design of a control unit as used within a computer microprocessor.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Distinguish between sequential logic building blocks: RS latches, JK, D, T flip-flops;
- Interpret timing diagrams;

- Distinguish between Mealy and Moore FSMs;
- Illustrate sequential arithmetic algorithms, including floating-point arithmetic;
- Describe the instruction cycle;
- Describe the buses and registers inside a computer microprocessor control unit;
- Distinguish between single-cycle, multicycle, and pipelined processors, and between hardwired and microprogrammed control units;
- Contrast SRAM and DRAM.

2. Skills:

By the end of the study-unit the student will be able to:
- Implement sequential logic circuits using flip flops;
- Design and Implement FSMs;
- Design a control unit using FSM techniques;
- Implement a sequential logic system in hardware.
