Your cache has a hit time of 1 clock cycle and a miss time of 100 clock cycles. If the CPI of your processor equals 1.3 with perfect caches (the cache always hits), then what is the CPI if your cache hits 71% of the time? Fill in the blank and show your work.

( )

Your cache has a miss penalty of 50 clock cycles and a hit time of 1 clock cycle. If your processor has a CPI of 1.5 with a perfect cache (it always hits), then what is your CPI if your cache always misses? one of them is correct.

		a. 1.5
		b. 50.5
		c. 51.5

Multiple-level caches are used because they?

a. provide a balance between low hit time and low miss rate.

b. have a higher combined hit rate than a single-level cache of the same size.

c. remove the need for a secondary memory.

Miss C has been on your unit for one week and states "these medications are not working properly;the doctor chose the wrong one". When you ask her why she believes that, she states, '' I'm not feeling any better yet, I'm still feeling sad and pathetic''. 5a) how would you respond to Miss C's concern that her medication is not working? Miss C is treated and released five weeks from her admission date. Five months later you are taking report...

A production process has a cycle time, time to produce a part, that is normally distributed with a mean of 12.6 minutes and a standard deviation of 2.4 minutes. Let X represent the cycle time for a part being produced. P( X > 17.4) = ______ Answer accurately to 4 decimal places. P( 11.4 < X < 16.2)= _______ Answer accurately to 4 decimal places. 97.5 percent of all parts are produced in less than _______ minutes. Enter your answer...

1. You want to design a pendulum for a grandfather clock so that it has a period of 2.00 seconds (so that one “tick” plus one “tock” occur during one complete period). The pendulum has a heavy 8.00-kg bob. (Throughout this problem, assume an ideal simple pendulum: the pendulum’s arm has negligible mass, the bob can be approximated as a point-mass, the initial angle of displacement is small, and there is negligible friction.) a.) If you want the clock to...

1. Computer A has an overall CPI of 1.2 and can be run at a clock rate of 600MHz. Computer B has a CPI of 2.5 and can be run at a clock rate of 750 MHz. We have a particular program we wish to run. When compiled for computer A, this program has exactly 100,000 instructions. How many instructions would the program need to have when compiled for Computer B, in order for the two computers to have exactly...

Biology lab question: 1. Molecular clock data place the evolution of diatoms around the time period following the Permian extinction. One hypothesis is that an adaptive radiation occurred as they colonized new marine niches. Based on what you know about the effects of ocean acidification on the formation of tests made from calcium carbonate and the composition of the tests (cell walls) of diatoms, what is a possible explanation for this diatom “explosion”? 2. what is the distinguishing features of...

Consider a 1Mbps transmission channel. The clock at the receiver has a drift of 1 second in one year. How long a sequence of bits(or frame)can be sent before the clock drift could cause a problem? Assume that the sender and receiver are synchronized at the beginning of each frame and that they cannot resynchronize during the frame .Also, assume that the receiver samples the received signal at the middle of each bit duration to detect if it is 0...
