Computer Architecture and Microprocessors Syllabus - BCIS (PU)

Course Objectives

This course will provide the fundamental knowledge to understand the basics, operation, programming and application of microprocessor and brief insight into computer architecture.

Course Description

This is a fundamental course for the microprocessor and computer architecture. 8085 microprocessor is taken as an example processor to deal with the details of the microprocessor. The course introduces about the microprocessors system and gives idea for assembly language programming and machine language programming with 8085 microprocessor. The course also deals with the hardware aspects of microprocessors such as memory interfacing, input/output interfacing, interrupt handling and some typical interfacing chips such as PPI and USART. The course also introduces the students about the parallel systems and different processor architecture.

Course Outcomes

After the completion of the course, students should be able to

• know basics of microprocessor and microprocessor based systems
• know the internal architecture of microprocessor
• write assembly language program
• solve various instructions such as data transfer, arithmetic, logical, branching etc. to solver various problems
• know various microprocessor operations and their timing diagrams
• interface various devices such as keyboard and seven segment displays
• know various interfacing standards
• handle interrupts

• have an idea about parallel systems and different processor architectures
