2- There are many different design parameters that are important to a cache’s overall performance. Below are listed parameters f

or different direct-mapped cache designs. Cache Data Size: 32 KiB Cache Block Size: 2 words Cache Access Time: 1 cycle Calculate the total number of bits required for the cache listed above, assuming a 32-bit address. Given that total size, find the total size of the closest direct-mapped cache with 16-word blocks of equal size or greater. Explain why the second cache, despite its larger data size, might provide slower performance than the first cache. You must show your work

Answer:

1. 2588672 bits

2. 4308992 bits

3. The larger the data size of the cache, the larger the area of ​​memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.

Explanation:

1. Number of bits in the first cache

Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))

total bits = 2^15 (1+14+(32*2^1)) = 2588672 bits

2. Number of bits in the Cache with 16 word blocks

Using the formula: (2^index bits) * (valid bits + tag bits + (data bits * 2^offset bits))

total bits = 2^13(1 +13+(32*2^4)) = 4308992 bits

3. Caches are used to help achieve good performance with slow main memories. However, due to architectural limitations of cache, larger data size of cache are not as effective than the smaller data size. A larger cache will have a lower miss rate and a higher delay. The larger the data size of the cache, the larger the area of ​​memory you will need to "search" making the access time and performance slower than the a cache with a smaller data size.

Under which of the following conditions will evaluating this boolean expression
zzz [600]
1.) 
<span>((i <= n) && (a[i] == 0)) || (((i >= n) && (a[i-1] == 0))) </span>

<span>The expression will be true IF the first part is true, or if the first part is false and the second part is true. This is because || uses "short circuit" evaluation. If the first term is true, then the second term is *never even evaluated*. </span>

<span>For || the expression is true if *either* part is true, and for && the expression is true only if *both* parts are true. </span>

<span>a.) (i <= n) || (i >= n) </span>

<span>This means that either, or both, of these terms is true. This isn't sufficient to make the original term true. </span>

<span>b.) (a[i] == 0) && (a[i-1] == 0) </span>

<span>This means that both of these terms are true. We substitute. </span>

<span>((i <= n) && true) || (((i >= n) && true)) </span>

<span>Remember that && is true only if both parts are true. So if you have x && true, then the truth depends entirely on x. Thus x && true is the same as just x. The above predicate reduces to: </span>

<span>(i <= n) || (i >= n) </span>

<span>This is clearly always true. </span>

densk [106]

A software EULA is an agreement related to the terms of use of the software

the terms of use of the software

<u>Explanation:</u>

EULA stands for End User License Agreement. It can be defined as an agreement related to the terms of use of the software. EULA provides the user with all the details and any restrictions that have been imposed on the application by the developer.

In order to use the software, the user has to agree with all the terms and conditions specified in the EULA. The most common restriction imposed on an application/software is that it shouldn't be shared with anyone, in proprietary software.
