Intel interview questions
1.Have you
studied buses? What types?
2.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 ?
3.How many
bit combinations are there in a byte?
4.For a single computer processor computer system, what is
the purpose of a processor cache and describe its operation?
5.Explain the operation considering a two processor computer
system with a cache for each processor.
6.What are the main issues associated with multiprocessor
caches and how might you solve them?
7.Explain the difference between write through and write
back cache.
8.Are you familiar with the term MESI?
9.Are you familiar with the term snooping?
10.Describe a finite state machine that will detect three
consecutive coin tosses (of one coin) that results in heads.
11.In what cases do you need to double clock a signal before
presenting it to a synchronous state machine?
12.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?
13.What are the total number of lines written by you in
C/C++? What is the most complicated/valuable program written
in C/C++?
14.What compiler was used?
15.What is the difference between = and == in C?
16.Are you familiar with VHDL and/or Verilog?
17.What types of CMOS memories have you designed? What were
their size? Speed?
18.What work have you done on full chip Clock and Power
distribution? What process technology and budgets were used?
19.What types of I/O have you designed? What were their
size? Speed? Configuration? Voltage requirements?
20.Process technology? What package was used and how did you
model the package/system? What parasitic effects were
considered?
21.What types of high speed CMOS circuits have you designed?
22.What transistor level design tools are you proficient
with? What types of designs were they used on?
23.What products have you designed which have entered high
volume production?
24.What was your role in the silicon evaluation/product
ramp? What tools did you use?
25.If not into production, how far did you follow the design
and why did not you see it into production? |
