凹凸的软件考试题目 1.Select ONE of the following projects to discuss:
a).Signal Filtering: You are given a sampled realtime
waveform consisting of a sensor reading mixed with
highly periodic impulses and high frequency noise.The
desired output is the realtime filtered sensor signal
with the impulses and noise removed, and a readout of
the impulse period. The FFT may not be used.
b).Interrupt Processing.A headware register consisting
of eight independent edge triggered latches is used to
record external asynchronous interrupt requests. When
any of the request bits are latched, a software interrupt
is generated. The software may read the latch to see which
interrupt(s) occurred. Writing a one to any latch bit will
clear the latch. How does that software assure that no
interrupt request is ever missed?
c).User Interface: a prototype MP3 player interface
consisting of a playlist display and a few control
buttons is given to you. How would you make the interface
"skinnable",with user selected graphics,options, and
control button placement?
Each project description is incomplete. What questions
would you ask to completely specify the project? What
development tools would you prefer to use? What algorithm
/data structures/design would you use?
2.What program(s) have you coded for you own enjoyment
(not part of a school project,not for pay).What type of
software project would you most enjoy working on?
3.Have you participated in a team programming project?
What is the hardest part of programming as a team, as
opposed to programming alone?
