Memory Management6. Memory ManagementDevise an example with 8 physical pages and 16 virtual pages and 10 page faults / references. Show how thepages are paged in / out (make assumption on the page replacement algorithm you use).The following picture shows an example with 8 physical pages and 16 virtual pages, with 8 page faults. Notewith 10 page faults asked in this question, with 10 > 8, the # of physical pages, some physical page(s) willbe paged out.Virtualaddressspace60K-64K X56K-60K X } Virtual page52K-56K X48K-52K X44K-48K 740K-44K X36K-40K 532K-36K X28K-32K XX24K-28K20K-24K16K-20K12K-16K8K-12K4K-8K1OK-4K 23064Physicalmemoryaddress28K-32K24K-28K20K-24K16K-20K12K-16K8K-12K4K-8KOK-4KPage frame

Write a program* that solves the producer - consumer problem. You may use the following pseudo code for implementation. *program to write: produce -consumer problem to produce and consume the alphabet. //Shared data: semaphore full, empty, mutex; //pool of n buffers, each can hold one item //mutex provides mutual exclusion to the buffer pool //empty and full count the number of empty and full buffers //Initially: full = 0, empty = n, mutex = 1 //Producer thread do { … produce next item … wait(empty); wait(mutex); … add the item to buffer … signal(mutex); signal(full); } while (1); //Consumer thread do { wait(full) wait(mutex); … remove next item from buffer … signal(mutex); signal(empty); … consume the item … } while (1); SAMPLE OUTPUT also attach your sample output too it will be in alphabetic as same output that i have attached
Assuming that you have a non-empty SQUARE matrix B of size n (assume n >= 2; assume n is a variable present in Workspace) available in your Workspace, which Matlab command will create a vector comprised of all element values present on matrix B diagonal? For example, if: B = 1 0 0 0 0 2 0 0 0 0 3 0 0 0 0 4 The result should be: 1 2 3 4 B(1:(n+1):end) B(1:n:end) B(1:(n-1):end) B(1:-n:end)

Im working with R code.
cache.xls (or it can be a google sheet that you share with me in a cache.txt with the url in it )= a spreadsheet showing the cycle counts of a cached and non-cached machine. Also, you need to show the cache as the memory accesses progress in your program marking the hits and misses (misses in RED). You should have cells to show how many hits and how many misses your program has, and details on what is the cache replacement policy you implemented. Here is code: void c_cache_for_badge() { int na = 8, nb = -3, nc = 10; // pointers int *npa; npa = (int*)malloc(sizeof(int)*84); // init integer pointers for(int i = 0; i < 84; i++) { npa[i] = i; } // integer pointers for(int i = 9; i < 70; i= i + 3) { nb += npa[i % 5] + npa[i % 3] + npa[i % 6]; } } void main() { c_cache_for_badge(); }
