凹凸电子软件笔试题
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 noi
se.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 us
ed.
b. Interrupt Processing.A headware register consisting of eight independen
t edge triggered latches is used to record external asynchronous interrupt req
uests. When any of the request bits are latched, a software interrupt is gener
ated. The software may read the latch to see which interrupt(s) occurred. Writ
ing 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 playli
st display and a few control buttons is given to you. How would you make the i
nterface “skinnable”,with user selected graphics, options, and control butto
n placement?
Each project description is incomplete. What questions would you ask to co
mpletely 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 sch
ool project,not for pay). What type of software project would you most enjoy w
orking on?
3. Have you participated in a team programming project? What is the hardes
t part of programming as a team, as opposed to programming alone?
