ECEN 4613 - Embedded System Design


Catalog Data ECEN 4613 (3). Embedded System Design. Introduces system hardware and firmware design for embedded applications. Students independently design and develop a hardware platform encompassing a microcontroller and peripherals. Firmware is developed in C and assembly. A significant final project is designed, developed, documented, and presented.
(Meets with ECEN 5613.)
Credits and Design 3 credit hours: 2 hours of lecture, 2 hours of lab per week, additional hours required outside formally scheduled hours. Elective course.
Prerequisite(s) ECEN 2350, Digital Logic
ECEN 3350, Programming of Digital Systems
C programming experience
Recommended prerequisite(s) ECEN 3250, Microelectronics
ECEN 4593, Computer Organization
Textbook No formal textbook. Data sheets and application notes are used.
  
Course Objectives To teach students all aspects of the design and development of an embedded system, including hardware and embedded software development. The course utilizes and applies the skills and knowledge students have gained throughout their prior undergraduate curriculum. Individual (rather than team) lab assignments ensure that each student is able to apply engineering theory to real world designs.
