Given the following mips code snippet (note that instruction #6 could be anything):
loop:
1. addi $t0, $t0, 4
2. lw $v0, 0($t0)
3. sw $v0, 20($t0)
4. lw $s0 60($t0)
5. bne $s0, $0, loop
6. ##the following instruction could be anything
a. detect hazards and insert no-ops to insure correct operation. assume no delayed branch, no forwarding units and no interlocked pipeline stages. your answer on the right should take the form of pair(s) of numbers: num@location – indicating num no-ops should be placed at location. e. g., if you wanted to place 6 noops between lines 2 and 3 (i. e., location=2.5) and 8 noops between lines 5 and 6 (i. e., location=5.5), you would write: "[email protected], [email protected]". b. now, reorder/rewrite the program to maximize performance. assume delayed branch and forwarding units, but no interlocked pipeline stages. for unknown reasons, the first instruction after the loop label must be the addi. feel free to insert no-ops where needed.

Kirk found a local community college with a two-year program and he is comparing the cost with that of an out-of-state two-year school. what is the expected total cost for one year at the local community college if kirk lives at home? what is the expected total cost for one year at the out-of-state school if kirk lives on campus?

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

Anul 2017 tocmai s-a încheiat, suntem trişti deoarece era număr prim, însă avem şi o veste bună, anul 2018 este produs de două numere prime, 2 şi 1009. dorel, un adevărat colecţionar de numere prime, şi-a pus întrebarea: “câte numere dintr-un interval [a,b] se pot scrie ca produs de două numere prime? “.
