ECE 4721/5721 - Embedded System Design (4)

Tuesday,Thursday

05:30 PM - 07:17 PM

Main Campus Campus | Mathematics and Science Center | Room 104

This course deals with advanced concepts in the programming and the interfacing of modern microprocessors/microcontrollers to the outside world as demonstrated by a variety of application examples. It covers the advanced architecture of modern processors and the many 1/0 peripherals now commonly found on-board. Laboratory activities provide the student with experience in developing the hardware and software required to incorporate microprocessors into systems that solve real-world interfacing problems

Prerequisites(s): ECE 3720 (UG), background in microprocessors (G)

• Understand and describe the generalized architecture of advanced microprocessors.
• Describe the ARM architecture and programmers model.
• Program the ARM microprocessor using C language.
• Develop algorithm/program of the ARM microprocessor for a particular task.
• Describe the memory management unit, the working of virtual memory, multitasking, memory organization, page tables, and translation look aside buffer in embedded operating systems.
• Describe how serial data can be sent from one microcontroller to another using CAN Interface.
• Describe the advanced microprocessor bus architecture (AMBA) bus system, user peripherals, exception handling, in ARM, and ARM optimization techniques.
• Interface advanced microprocessors with external peripherals.
• Work in a team environment to design a microprocessor-based system and communicate the results in a written report and an oral presentation.
