As part of an effort to update its core computer engineering courses, Boise State University has developed course material to effectively transition students in a Microprocessors course through both the assembly and C languages. It was found that teaching both languages in the same course provides benefits not found in teaching them separately. The material has been developed to promote both a thorough understanding of microprocessors, and greater productivity that allows students to do more intriguing and relevant projects. The course presents just enough C, at a very low level and in a specific topic order, to enable the students to better comprehend microprocessors and how they can control a broad range of devices. The updated Microprocessors course is currently in its fourth iteration.
