Unformatted text preview: Score: Name: 1. (5 points) AMD’s Athlon chips are labeled with the equivalent Intel chip clock
frequency to indicate the relative performance for marketing purposes. AMD was worried
that a lower frequency clock on the AMD chip would hurt sales. The AMD Athlon 3000 (program execution time performance equivalent to a 3Ghz Intel chip) actually has a
2167Mhz clock. / Extav't\‘°nT:M¢-A I)“: Exec/+1,“ Il‘mein‘fﬁl

operation 32 times faster. C? "l“ 2/1: G.II§M7 A DSP application that runs in 10 ms (ms is 104' sec) spends 40% of its execution time
performing multiply operations. With the hardware multiplier, the DSP application would run in Q . ‘15 ms. (accurate to 3 decimal places) 470031935 .31
