CEC 612 FPGA Based Embedded Systems Exam 2022

About this paper

CEC 612: A second-semester examination (17/06/2022, 3 hours) for FPGA Based Embedded Systems (CEC612) at the University of Buea, College of Technology, instructors Pr. Sone and Dr. Gamom. Section A (VHDL/cryptography, 40 marks): Question One implements the password-hashing steps (input, append, hash) of a claimant-verifier authentication scheme with given userid, password and initialization vector; Question Two implements the Vigenere cipher's encoding steps for given plaintext and key. Section B (embedded systems modeling, 30 marks): Topic 1 covers the purpose of modeling, embedded task types, and extended-state-machine modeling of an Arduino push-button/LED brightness-cycling program. Topic 2 covers modeling and designing a two-servo windscreen-wiper control system (button state machine, servo state machine, Arduino implementation using a Servo_balai class, and a Proteus hardware simulation proposal).
