Assume that the 100,000 element integer array that you allocated starts at address 0x50000000 in memory, the size of an integer is 4 bytes and the D-cache is initially empty. As you read the integers in the array one-by-one, starting at index 0, how many D-cache misses will you see for reading the first 40 integers when the cache block size is (to be answered without running pin):a) 4 bytes:b) 32 bytes:c) 64 bytes:

40, 5 and 3

See explaination for the details

Explanation:

A)

Consider the data.

Assume D-cache is empty

An integer size =4bytes

The cache block size =4bytes

Therefore, the number of D-cache misses for reading the first 40 integers is,

= (40×4)/4

= 160/4

= 40

b)

Consider the data.

Assume D-cache is empty

An integer size =4bytes

The cache block size =32bytes

Therefore, the number of D-cache misses for reading the first 40 integers is,

= (40×4)/32

= 160/32

= 5

c)

Consider the data.

Assume D-cache is empty

An integer size =4bytes

The cache block size =64bytes

Therefore, the number of D-cache misses for reading the first 40 integers is,

= (40×4)/64

= 160/64

= 3

answer; always; never;

the benefits of raising bc’s minimum wage to $15 through a

series of pre-announced staged increases far outweigh the likely

costs. claims that such an increase will lead to massive job losses

in low-wage sectors of the economy are not credible.

• an increase to $15 would result in some job losses. however,

the likely impact is less than a 1 per cent reduction in the overall

provincial employment rate, and a 7.6 per cent reduction in the

employment rate for those currently making between $10.25

and $15 per hour.

• the large job loss impacts predicted by some opponents of

minimum wages misrepresent the existing economic research. in

reading and using that research, it is important to recognize that

estimates showing job loss effects of minimum wage increases

apply only to teenagers. estimated effects for young adult and

adult workers range from insignificant to non-existent.

• focusing on teenage workers plays up an inaccurate stereotype

about who earns very low wages in bc and leads to exaggerated

claims about job losses. only 26 per cent of those currently making

between $10.25 and $12 are teenagers, and only 5 per cent

of those making between $12 and $15 are teenagers.
