MCQ on Assembly and Embedded Firmware

What does assembling a source file produce?

• Executable file

• Object file

• Source file

• Binary image

What is the role of a linker/locator in embedded development?

• Writes high-level code

• Manages power supply

• Assigns absolute addresses to object files

• Connects sensors to the microcontroller

Which type of code does an object file contain?

• Absolute address code

• Re-locatable code

• Bootloader code

• BIOS instructions

Why is memory optimization important in embedded systems?

• To increase system temperature

• To reduce execution speed

• To make better use of limited code and data memory

• To slow down the processor

What benefit does optimized assembly code offer apart from memory savings?

• More power consumption

• Increased development time

• Higher system performance

• Larger object files

Where is direct assembly coding often used?

• Graphic design software

• Word processors

• Device drivers and interrupt routines

• Cloud-based applications

What is code reverse engineering?

• Writing firmware from scratch

• Testing embedded products

• Extracting information from a finished product

• Encrypting product firmware

What challenge is commonly associated with using assembly language?

• Too many available tools

• Low dependency on developers

• High development time

• Easy reuse across all processors

Why can assembly language not be reused across different processors?

• It's written in English

• It's compiled at runtime

• It's specific to a processor's instruction set

• It's written only for Windows OS

What is a cross-compiler used for?

• Debugging memory errors

• Turning assembly into C++

• Converting high-level code to machine-specific code

• Running simulations
