MICROPROCESSORS

This page collects 150 microprocessors questions taken from 6 BEU semester 5 papers, 2020 to 2025 — about 25 questions in a typical paper. They are sorted into the 6 modules of the syllabus, so you can revise a topic across every year at once instead of working through papers one at a time. 150 of them have a worked solution.

What these papers actually ask

Module 2: The 8051 Architecture is the heaviest module in this archive at 34% of every question recorded, and it has come up in all 6 papers. Together with Module 3: Instruction Set and Programming, the two account for 55% of the archive.

4 modules have appeared in all 6 papers — Module 2: The 8051 Architecture, Module 3: Instruction Set and Programming, Module 1: Fundamentals of Microprocessors, Module 5: External Communication Interface. A module that turns up every year is a safer use of revision time than one with the same question count concentrated in a single paper.

How the marks are split

Questions in this archive carry 8 different mark values. The most common is the 7-mark question, with 76 of them recorded — worth knowing before you decide how much depth to practise at.
