EE2310 Introduction to Digital Systems (3 semester credit hours) Introduction to digital circuits, hardware structures, and assembly-language concepts that underlie the design of modern computer systems. Topics include: Internal data representation and arithmetic operations in a computer, basic logic circuits, MIPS assembly language and an overview of computer architecture. Some knowledge of a high-level language such as C++ or Java is expected. This class also has a laboratory component. Exercises will be assigned in class for completion in the laboratory. This class may be offered as either regular or honors sections (H). (Same as CE 2310) (3-1) S

Digital systems are designed to store, process, and communicate information in digital form. They are found in a wide range of applications, including process control, communication systems, digital instruments, and consumer products. The digital computer, more commonly called the computer, is an example of a typical digital system.

Digital systems are pervasive in modern society. We use computers for bookkeeping, engineering, publishing, and entertainment. Digital communications systems handle our telephone calls and enable our Web browsing sessions. Other uses of digital systems are less visible. Most consumer electronics products are largely digital and becoming more so. Music today is distributed digitally on compact optical disks, and video production is rapidly becoming a digital process. A typical appliance is controlled digitally by a microcomputer. As many as ten microcomputers can be found in the average car for controlling functions ranging from the sound system to the antilock brakes.

A digital system represents information with discrete symbols (of which digits are a special case) rather than with a continuously varying quantity, as in an analog system. Most systems use just two symbols, often denoted by the binary digits (or bits) 0 and 1, to represent all information. Simple truth propositions are represented directly with a single bit, whereas strings of bits are used to represent more complex data.

In a digital system, noise below a given level can be completely rejected. Symbols are encoded into ranges of voltage or current level. If we add a small amount of voltage, VN, to the nominal voltage for the 0 symbol, V0, the resulting voltage, V0 + VN, will still be in the range for a 0 symbol and, more importantly, can be restored to the nominal level, V0. This property allows us to process information through many noisy stages of logic with no accumulation of noise.

A first course in the analysis and design of digital systems. Introduces digital system design using schematic-based entry and hardware description language-based entry. Boolean algebra, combinational and sequential logic, state machine design, test benches and various hardware modeling styles. Offered fall and winter semesters. Prerequisite: EGR 112 (grade of C or higher) OR EGR 108 (grade of C or higher).

A brief orientation to University life and resources and an introduction to computers and computer hardware. CMPEN 111S Computers and Computer Hardware (1)This course contains two components: an orientation to University life and an introduction to the hardware aspects of computer engineering. In the orientation to University life, students learn about the responsibilities of and expectations on a student including ethical behavior, and explore some of the academic and non-academic resources of the University. In the introduction to computer engineering students learn about some of the fundamental concepts, devices, and methodologies that are involved in the design and use of digital and computer hardware. This exploration begins with a foundation of logic and critical thinking. Logic is examined first from a theoretical problem solving standpoint. The discussion then progresses to an implementation perspective examining how logic devices are created and used. Included is a look at some CAD tools and some logic design laboratory exercises. Using logic as a basic building block, the organization and design of a computer is then examined, ending in an exploration of some of the contemporary methods used to make computers faster and more efficient.

Introduction to digital systems and their design. Topics include combinational and sequential devices and circuits, modern design tools and design practices. Students may take only one course for credit for CMPEN 270 or CMPEN 271 and CMPEN 270 or CMPEN 275. CMPEN 270 Digital Design: Theory and Practice (4)CMPEN 270 is a first course in digital systems and digital system's design. It lays the groundwork for many later courses in computer organization and architecture and switching theory. The course includes both a lecture component to introduce important concepts, principles, methodologies and theories and a laboratory component in which the lecture material can be applied and practiced. The course introduces the theoretical foundation for digital systems including number systems, a variety of commonly used codes and Boolean algebra. Combinational devices, logic gates, and sequential devices, latches and flip-flops are introduced along with design techniques, methods and tools. Design criteria and objectives are considered and design trade-offs are examined. Higher level design elements are also examined such as decoders, multiplexers, counters, and registers, and their use in system design. Students are exposed to a variety of design tools and implementation techniques, including schematic capture tools, simulation tools, Hardware Description Languages (HDL) and HDL design tools. Laboratory work includes the design, construction and debugging of a variety of digital circuits, and the use of standard laboratory tools such as the oscilloscope and logic analyzer, and various software design tools.

Introduction to logic design and digital systems. Boolean algebra, and introduction to combinatorial and sequential circuit design and analysis. Students may take only one course for credit for CMPEN 270 or 271. CMPEN 271CMPEN 271 Introduction to Digital Systems (3)This course introduces students to logic design and digital systems. The course begins with an overview of number systems, base conversions, and binary arithmetic. Boolean algebra is presented and several basic theorems and postulates are introduced. Boolean algebra is then used to model digital devices. Canonical forms for expressing Boolean functions are introduced including sum-of-products and product-of-sum forms.Basic Small Scale Integrated (SSI) combinational devices are introduced along with a description of their operations characterization, and use. The basic symbols used in a logic diagram/schematic are introduced and the principles involved in reading and creating logic diagrams/schematics are discussed.A systematic design methodology for combinational circuits is covered, including the concepts of function minimization using Karnaugh maps, handling don't care conditions, and designing multiple output circuits. Medium Scale Integrated (MSI) combinational devices and functions such as multiplexors and decoders are discussed and their use in a variety of applications is explained. Simple programmable logic devices and their use in implementing combinational functions is covered. The process of combinational circuit analysis is discussed and the use and interpretation of timing diagrams is introduced.

INTRODUCTION TO MAJOR COMPONENTS OF A COMPUTER SYSTEM, HOW THEY FUNCTION TOGETHER IN EXECUTING A PROGRAM, HOW THEY ARE DESIGNED. CMPEN 331 Computer Organization and Design (3) The goals of the course are to introduce students to the major components of a computer system (the data path, the control path, the memory system, the I/O system), how they function together in executing a program, and how they are designed. The relationships between instruction set design, addressing modes, fetch and execute operations, and their impact on the underlying architecture are presented. Students will develop skills both in assembly language programming and in designing architecture components in a hardware description language (VHDL or verilog).CMPEN 331 is a required course for both computer engineering and computer science majors.CMPEN 331 requires access to PCs/workstations with commercial hardware description language tools (e.g., Synopsys VSS compiler and simulator) and a modern assembler/debugger (e.g., SPIM MIPS assembler, simulator, and debugger).
