3.2. Assume at time 5, no system resources are being used except for the processor and memory. Now consider the following events: At time 5: P1 executes a command to read from disk unit 3. At time 15: P5’s time slice expires. At time 18: P7 executes a command to write to disk unit 3. At time 20: P3 executes a command to read from disk unit 2. At time 24: P5 executes a command to write to disk unit 3. At time 28: P5 is swapped out. At time 33: An interrupt occurs from disk unit 2: P3’s read is complete. At time 36: An interrupt occurs from disk unit 3: P1’s read is complete. At time 38: P8 terminates. At time 40: An interrupt occurs from disk unit 3: P5’s write is complete. At time 44: P5 is swapped back in. At time 48: An interrupt occurs from disk unit 3: P7’s write is complete. For each time 22, 37, and 47, identify which state each process is in. If a process is blocked, further identify the event on which it is blocked.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
