🔥 Most Predictable Exam Questions (1)

Guaranteed Every Year 8 Marks Module 1: ARM Architecture

Q1. Explain the architecture and register organization of the ARM Cortex-M3 processor (R0-R12, SP, LR, PC, PSR) and describe the vector table exception handling mechanism.

Key Points: Draw Cortex-M3 32-bit register bank. R0-R7 low registers, R8-R12 high registers. MSP and PSP banked stack pointers. LR (R14) link register, PC (R15) program counter, xPSR program status. Nested Vectored Interrupt Controller (NVIC) automatic hardware state saving.
