Course: Microprocessor and Computer Architecture Code: EI 402 Program: Electronics and Instrumentation Engineering This course aims at teaching primary concept of programing with machine language. It also aims to train the student for automated system design with the programing intelligence. This course assumes a course in digital as a prerequisite. At the end of the course, a student will be able to: 1. 2. 3.

4. 5. 6.

Identify and state function of different module like ALU, Register, and Buses in a computerised system. Demonstrate programming proficiency using the various addressing modes and data transfer instructions of the 8085 microprocessor. Apply knowledge of the microprocessor’s internal registers and operations by use of a PC based microprocessor simulator. Program using the capabilities of the stack, the program counter, and the status register and show how these are used to execute a machine code program. Draw a timing diagram for a multiplexed bus CPU-memory interface Conduct experiments for real time data collection through ADC, 8255 PPI. Design electrical circuitry to the Microprocessor I/O ports in order to interface the processor to external devices real-world control problems such as fluid level control, temperature control, and batch processes.

PREREQUISITES To understand this course, the incumbent must have idea of: Digital electronics.
