The following are some not too difficult Intel interview questions.

--Have you studied buses? What types?

--Have you studied pipelining? List the 5 stages of a 5 stage pipeline. Assuming 1 clock per stage, what is the latency of an instruction in a 5 stage machine? What is the throughput of this machine ?

--How many bit combinations are there in a byte?

--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 them?

--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.

--In what cases do you need to double clock a signal before presenting it to a synchronous state machine?

--You have a driver that drives a long signal & connects to an input device. At the input device there is either overshoot, undershoot or signal threshold violations, what can be done to correct this problem?

--What are the total number of lines written by you in C/C++? What is the most complicated/valuable program written in C/C++?

--What compiler was used?

--What is the difference between = and == in C?

--Are you familiar with VHDL and/or Verilog?

--What types of CMOS memories have you designed? What were their size? Speed?

--What work have you done on full chip Clock and Power distribution? What process technology and budgets were used?

--What types of I/O have you designed? What were their size? Speed? Configuration? Voltage requirements?

--Process technology? What package was used and how did you model the package/system? What parasitic effects were considered?

--What types of high speed CMOS circuits have you designed?

--What transistor level design tools are you proficient with? What types of designs were they used on?

--What products have you designed which have entered high volume production?

--What was your role in the silicon evaluation/product ramp? What tools did you use?

--If not into production, how far did you follow the design and why did not you see it into production?
