Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec
Answer:
TRUE
Explanation:
Cache memory is a computer component that help to retrieve data from the computer's memory by acting as a temporary storage area where the computer's processor can retrieve data easily. The temporary storage area is known as cache and is more readily available to the processor than the computer's main memory source.
Although Cache memory is a smaller type of a computer memory that provides high-speed data access to a processor and stores which frequently used computer programs, applications and data.
Cache memory is used to reduce the average time to access data from the Main memory and they stores data so that future requests for that data can be served faster.
Answer: 5G high bands (mmWave, also referred to as FR2) are found in the range of 24GHz to 40GHz. They deliver large quantities of spectrum and capacity over the shortest distances
