Answer: 200 nanoseconds

Explanation:

If a memory reference is taking 100 nanoseconds

Then, a paged memory references take two memory access which are getting the number of frame from the memory for page number and followed by this accessing of the data/information.

Thus, the time taken by the paged memory reference is

Time= 2\times100 nanoseconds

Time=200 nanoseconds

Phantasy [73]

Answer:

Explanation:

This is a project I already submitted, but I never received feedback. All my upcoming assignments will be based on this, so I wanted to make sure it is correct. I got this program to work as far as calculating the information, but I was hoping someone could please let me know if it meets the parameters/requirements?

I did attempt it. It works and adds the items exactly how the example showed in the video. However, I wanted to make sure my code is solid, and not just a mishmash or working because I got lucky, and if there is a better more solid way to do this I want to make sure I can. I do want feedback so I can learn and get better and I am trying my hardest. I always right out all the code I see here and try it and learn what it does piece by piece, because it helps me learn and improve. I also want to make sure it is going to work once I start the code for the next half of the requirements.

i cant really help they dont let us put codes on here

g The machine in the problem has a byte-addressable memory of 216 bytes. The direct-mapped cache consists of 32 cache blocks, an
balu736 [363]

Answer / Explanation:

To properly answer this question, let us define some basic terms:

Byte: The term byte is the digital unit for information and mostly consists of eight bits. The byte used to be the number of bits used to encode a single character of text in a computer and for this reason it is the smallest unit of memory in many computer program

Cache: A cache can be refereed to as a software component that stores information or data for the purpose future recall. The data stored in a cache could be treated as a duplicate or a copy of a copy of another data stored elsewhere.

Now, with the understanding from the above definition, referring back to the narrative of the question asked, we have:

(1) 8 leftmost bits = tag; 5 middle bits = line number; 3 rightmost bits = byte number.

                                                          S

                                               Tag           Set slot           W            

Memory address = 16 bits       8                 5                  3

(2)  256 bytes.=2^8 or

      32 blocks * 8 byte = 256 byte

(3)   Because two items with two different memory addresses can be stored in the same place in the  cache. That is, The tag is used to distinguish between them.

(4) Line 3.

    Line 6.

    Line 3.

    Line 21
