ARM Processors are used in a wide range of devices, from phones to tablets to wearables. They are known for their low power consumption and high performance. If you are interviewing for a position that uses ARM Processors, it is important to be prepared to answer questions about them. In this article, we will review some of the most common ARM Processor interview questions and how you should answer them.
If you want to learn STM32 from scratch, you should follow this course “Mastering Microcontroller with Embedded Driver Development“. The course contains video lectures of 18.5-hours length covering all topics like, Microcontroller & Peripheral Driver Development for STM32 GPIO, I2C, SPI, USART using Embedded C.
I hope these embedded system interview questions with the answer will be helpful. If you have any other important questions relate to the embedded systems and concepts or want to give the answer to any mentioned embedded systems interview questions, then please write in the comment box. It is helpful to others.
It is an important question that is asked by the interviewer to test the understanding of Interrupt. Basically, interrupt latency is the number of clock cycles that are taken by the processor to respond to an interrupt request. This number of the clock cycle is count between the assertions of the interrupt request and the first instruction of the interrupt handler.
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but can also be used in many other contexts.
This article is mainly focused on the most repeatedly asked embedded system interview questions. If you are looking for “embedded system interview questions” or “simple questions on embedded systems”, then you at the right place.
Interview Query regularly analyzes interview experience data, and weve used that data to produce this guide, with sample interview questions and an overview of the ARM Software Engineer interview.
Typically, interviews at ARM vary by role and team, but commonly Software Engineer interviews follow a fairly standardized process across these question topics.
Getting ready for an Software Engineer interview at ARM? The ARM Software Engineer interview span across 10 to 12 different question topics. In preparing for the interview:
ARM and Intel processors are both popular choices for embedded systems and mobile devices. ARM processors are typically more power-efficient than Intel processors, but they may not offer the same level of performance. In terms of instruction sets, both ARM and Intel processors support a wide variety of instructions, but ARM processors typically have a smaller instruction set than Intel processors. In terms of performance, ARM processors are typically slower than Intel processors, but they consume less power, which can be important in mobile devices. In terms of cost, ARM processors are typically less expensive than Intel processors. In terms of memory, both ARM and Intel processors support a wide variety of memory types, but ARM processors typically have less cache memory than Intel processors.

Mode switching is used to change the state of the processor in order to run different types of code. For example, you might have a processor that is in user mode most of the time, but when it needs to run a privileged instruction, it will switch to supervisor mode. This allows the processor to maintain security by only allowing certain types of code to run in privileged mode.
The instruction set architecture used by ARM processors is a RISC (Reduced Instruction Set Computer) architecture. This means that the instruction set is designed to be simple, and that the processor can execute instructions quickly. The trade-off is that RISC architectures generally have fewer features than CISC (Complex Instruction Set Computer) architectures.
The bit size of an ARM processor refers to the width of the data bus. A 32-bit data bus can transfer 4 bytes of data at a time, while a 64-bit data bus can transfer 8 bytes of data. The bit size also determines the maximum addressable memory, so a 32-bit processor can address 4 GB of memory, while a 64-bit processor can address 16 GB of memory.
