Hardware / Microprocessor Interview Questions
x86 Interview Questions
- What is a Microprocessor? - Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor are single- chip devices.
- Give examples for 8 / 16 / 32 bit Microprocessor? - 8-bit Processor - 8085 / Z80 / 6800; 16-bit Processor - 8086 / 68000 / Z8000; 32-bit Processor - 80386 / 80486.
- Why 8085 processor is called an 8 bit processor? - Because 8085 processor has 8 bit ALU (Arithmetic Logic Review). Similarly 8086 processor has 16 bit ALU.
CPU engineer interview questions
- For a single computer processor computer system, what is the purpose of a processor cache and describe its operation?
- Explain the operation considering a two processor computer system with a cache for each processor.
- What are the main issues associated with multiprocessor caches and how might you solve it?
- Explain the difference between write through and write back cache.
- Are you familiar with the term MESI?
- Are you familiar with the term snooping?
- Describe a finite state machine that will detect three consecutive coin tosses (of one coin) that results in heads.
