Virtual memory layout [20] You have a 64-bit machine and you bought 8GB of physical memory. Pages are 256KB. For all calculations, you must show your work to receive full credit. (a) [1] How many virtual pages do you have per process? (b) [1] How many bits are needed for the Virtual Page Number (VPN)? (Hint: use part (a)) (c) [1] How many physical pages do you have? (d) [1] How many bits are needed for the Physical Page Number (PPN)? (Hint: use part (c)) (e) [1] How big in bytes does a page table entry (PTE) need to be to hold a single PPN plus a valid bit? (f) [1] How big would a flat page table be for a single process, assuming PTEs are the size computed in part (e)? (g) [10] Why does the answer above suggest that a "flat page table" isn't going to work for a 64-bit system like this? Research the concept of a multi-level page table, and briefly define it here. Why could such a data structure be much smaller than a flat page table? (h) [4] Does a TLB miss always lead to a page fault? Why or why not?
We have 2^48 pages per person. The number of physical pages is 2^16.. 48 bits of VPN are mapped to 16 bits of PPN. The PTE size is 2B. The page table size is 2^49 B.
What are the steps to calculate pages per person, physical pages, VPN ,PTE size and the table size?We know that;
Virtual Address = 64bits
Virtual Address Space = 2^Virtual Address = 2^64B
Physical Address Space = 4GB = 4 X 2^30 B = 2^32 B
Physical Address = log_2(Physical Address Space ) = log_2(2^32)
= 32 * log_2(2) = 32 bits.
Page size = 64KB =2^16 B
a) No of Virtual Pages = Virutal Address Space/PageSize
= 2^64B / 2^16 B = 2^48
b) NoOfPhysicalPages = PhysicalAddressSpace/PageSize
= 2^32 B / 2^16 B = 2^16
c) VPN (in Bits) = log_2(NoOfVirtual Pages) = log_2(2^48) = 48
PPN(inBits)=log_2(NoOfPhysicalPages)= log_2(2^16) = 16
Thus 48 bits of VPN are mapped to 16 bits of PPN.
d) PTE( Page Table Entry) holds the Physical Page Number of given Virtual Page along with many information about the page.
PTEsize = PPN(inBits) = 16 bits = 2B
e) Flat page table is single level page table. A page table contains the Physical Page number for a given page number. It helps in the translation of Vitual Address to Physical Address.
PageTableSize = NoOfVirtualPages*PTEsize = 2^{48}*2B = 2^49

Determine all cache accesses and the state of the data cache at any given time. From this you can determine any additional cycles from data cache misses. You must calculate the number of bits for the offset, index, and tag, determine the number of hits and misses, show the contents of the cache, and use the number of misses to determine any additional clock cycles required. The total clock cycles would be the total cycles for all iterations from Part 2 plus any additional memory access cycles from cache misses from Part 3.
The smallest and fastest part of a computer system's memory is the cache. The registers, which make up a very minor portion of the computer CPU, are quick storage components.
Why does the cache memory access time take less time than the main memory access time?Cache memory must be substantially smaller than main memory in order to be situated near to the CPU. As a result, it has less room for storage. Due to the increased performance of the more complicated chip, it is also more expensive than main memory.
What distinguishes Level 1 from Level 2 and Level 3 cache benefits?Since it is the smallest and nearest to the CPU, Level 1 (L1) cache memory is the quickest type.

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
You must pipe the command's output through grep in order to utilize grep as a filter. " | " is the symbol for pipe.
Explain about the grep?The full line containing the matched string is displayed by default when using grep. To display only the matched pattern, change this setting. Using the -o option, we may instruct grep to show only the matching string. Using grep -n, output should be displayed together with the line number: To display the file's line number where the matching line was found.
Within collections of files, the grep command can look for a string. It outputs the name of the file, a colon, the line that matches the pattern, and the pattern when it discovers a pattern that matches in more than one file.
Instead of putting a filename at the end of a grep command, use an asterisk to search all files in the current directory.

one drawback to the sequential search is that it cannot be used with an array that contains string elements. T/F
The sequential search has the limitation that it cannot be utilized with arrays containing string elements.Thus, it is false.
What sequential search, an array contains string elements?Searching linearly over an array of strings for the supplied string is an easy fix. Performing a modified binary search is a better solution.
Get the list of arrays. Get each element of the Array List object using the for-each loop. Make sure the array list's elements all contain the necessary string. Print the elements if applicable.
We compare the given string with the middle string, just like in a standard binary search. If the middle string is empty, we linearly search on both sides for the nearest non-empty string x.
Therefore, it is false that one drawback to the sequential search is that it cannot be used with an array that contains string elements.

Explanation:
design a 32 bit counter that adds 4 at each clock edge the counter has reset and clock inputs upon reset the counter output is all 0
The counter is a digital sequencer, here a 4-bit counter. This simply means that you can count from 0 to 15 or vice versa depending on the counting direction (up/down).
The counter value (“count”) is evaluated on each positive (rising) edge of the clock cycle (“clk”).
If the "reset" input is logic high, the counter is set to zero.
If the "load" signal is logic high, the counter is loaded with the "data" input. Otherwise, count up or count down. If the "up_down" signal is logic high, the counter counts up, otherwise it counts down.
What are counters and their types
A counter is a sequential circuit. A well-known counter is a digital circuit used for counting pulses. Counters are the widest use of flip-flops. There are two types of counters. Asynchronous or ripple counter.
