Q1Domain Verified

In the context of the ARM Cortex-M architecture, what is the primary advantage of using the Thumb-2 instruction set over pure Thumb or ARM instructions for embedded applications?

Enhanced direct memory access (DMA) capabilities for faster data transfers.

Increased instruction density leading to smaller code size, with minimal performance penalty.

Significantly higher clock speeds achievable due to simpler instruction decoding.

Expanded register file size to accommodate more complex algorithms.

Q2Domain Verified

The ARM Cortex-M architecture utilizes a Nested Vectored Interrupt Controller (NVIC). What is the key benefit of this design in real-time embedded systems compared to traditional interrupt handling mechanisms?

It eliminates the need for explicit interrupt service routine (ISR) return instructions, simplifying code.

It allows for dynamic reallocation of interrupt priority levels during runtime without system reinitialization.

It enables interrupts to directly access the processor's internal memory map without context switching.

It provides hardware-based prioritization and automatic nesting of interrupts, reducing latency and jitter.

Q3Domain Verified

Consider a scenario where a Cortex-M processor needs to perform a complex mathematical operation. Which of the following memory access patterns would most likely lead to optimal performance, assuming the data is aligned?

Stride-based access to 64-bit double words with a stride of 8 bytes.

Bursty reads of 32-bit words from a peripheral register.

Random access to individual 16-bit half-words scattered across memory.

Sequential access to individual bytes within a large array.
