Course Objectives: This course will introduce the concepts of general aspects of stored program computers. The popular microprocessor Intel 8086 and micro controller Motorola M68HC11 will be used as the vehicles for exemplifying these concepts. The study of these processors, however will be limited to the programming viewpoint of using these processors.

The laboratory exercises deal with a wide range of problems covering the above topics. The students are expected to develop well-structured codes and submit fully documented reports for each laboratory exercise.
