Acomputer architect needs to design the pipeline of a new microprocessor. she has an example program with 106 instructions. each instruction takes 600 ps to finish.
a. how long does it take to execute this program on a non-pipelined, single-cycle processor?
b. assume the current state-of-the-art pipeline has 30 stages. assume also that the stages are perfectly balanced. how much speedup will it achieve compared to the non-pipelined processor?
c. realistically, we cannot achieve ideal speedup due to the overhead of implementing pipelining stages (e. g. imperfectly balanced stages, adding pipeline registers, etc). does this overhead affect the instruction latency, instruction throughput, or both? for each metric affected, is the effect significant? why or why not?
answer with explanation:
when dealing with heavy loads, one needs to take certain precautions in order to avoid or prevent from injuries.
for instance, one should avoid lifting above the shoulder level which can end up pulling your muscle.
also, you can either break the load in parts if possible or get some for lifting heavy bulks.
moreover, one should try to lift with the legs while keeping the back straight and not twisting it.
answer & explanation:
"the force on a cutting tool are 2600n vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "on the tool" is upwards. we will accept the statement as it is (downwards).
since the two forces are acting at right angles to each other, the resultant can be found using pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 n (approx.)
the angle can be found using the arctangent function, or
angle = arctangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 n force is acting downwards.
