For this assignment, you are to write a MIPS assembly language program using the MARS IDE and assume a system has 31-bit virtual memory address (so no worry about negative numbers) with a 4-KB page size (4096 bytes). Write a MIPS program that accepts an integer input that represents a virtual address and outputs the page number and offset for the given address in decimal. The output should look like: The address 19986 is in: Page number = 4 Offset = 3602 Check to make certain your program works. You can use the output from 19986 given above as a test, but I will use other numbers to test it. Submit the MIPS assembly language code and a screenshot showing a test run.

- Write a Java program that prompts the user for the page size used in a virtual memory system; this will be a power of two between 512 (29) and 16384 (214), inclusive. Your program should check the user input for page size to make sure it is one of the allowable inputs (must be a power of 2 and cannot be smaller than 512 or larger than 16384), and should then prompt the user for a virtual address (assume 32-bit virtual addressing, so your code must be able to accept any input between 0 and 4294967295, which is 232-1). Given this input, the program must output the virtual page number and the offset within the page. Sample output might look like this: Please enter the system page size: 1024 Please enter the virtual address: 10000 This address is in virtual page: 9 At offset: 784Write a program in HACK assembly, without using symbols, that computes thebitwise exclusive or (XOR) of the values stored in RAM[1] and the value of thememory location with address stored in RAM[2]. The result of the computationshould be stored in RAM[0].You can think of RAM[2] as being a pointer to where the second operand of the XORis stored.rite an assembly program for the processor family x86-32 that reads three real numbers from the keyboard and shows on the console the average value of them. In your implementation include the function averageOfThree and define for that function the interface below. averageOfThree: ; Input: Three memory addresses on the stack of three 64-bit floating point numbers in main memory. ; Output: The average value of the three input numbers on the stack as a 64-bit floating point number. ;TODO ret
- Write a program that can create a ‘short address' from a longer one. The program should be able to receivean address that has a fixed format but is of arbitrary length, and convert that to a specified shorter format.All input addresses will have the following format: address-line-1, address-line-2, ..., address-line-n, postcodeNote that there is a space character after each comma.All postcodes will have the following format:adddaa.Where a is an alphabetic character and d is a digit.For example, the address 56 Clapham Gardens, Stoke Newington, London, N145PX has the given format.As does 3 Acacia Ave, E178PU.The short address that your program generates must have the following format:address-line-1 postcodeNote that there is no comma in this string but there is a space between address-line-1 and postcode.For the examples above, the short addresses would be:56 Clapham Gardens N145PX and 3 Acacia Ave E178PU.Your class must contain the following method:public String…Assembly LanguageDefine a subroutine “count_letters” that would count the number of letters (a-z, A-Z) inside anull-terminated string of ASCII characters. The subroutine will receive the address of the string in X and return the count in D. Write a program that would define a string in Flash memory (ROM) and use this subroutine to test it.Consider a computer that has a byte-addressable memory organized in 32-bit words according to the big-endian scheme. A program reads ASCII characters entered at a keyboard and stores them in successive byte locations, starting at address 500. Show the contents of the two memory words at addresses 504 and 508 after the characters “Computer#ece@OSU" have been entered. Give the contents for the two words in hexadecimal. Repeat this problem for the little-endian scheme. ´sM
- I have a 128-bit computer where addresses are 128 bits wide. I want to implement virtual memory with paging for this computer, and I want to use a page size of 4KB. I will design it so that a page table consumes exactly one page. How many page table entries (PTEs) fit within a page?Case Study Assume a computer system has a main memory of 256 Bytes. The following is a memory byte-access trace history of a program run on this system. For example, as it is shown, the program first accesses memory address 0000 0000, and then it accesses memory address 0000 0001 and so on. Note the memory addresses are represented in binary: 00000000, 00000001, 00000010, 00000011, 00001000, 00010000, 00010001, 00000100, 00000101, 00000110, 00000111, 00001001, 00001010, 00001011, 00001100, 00001000, 00001001, 00001010, 00011100, 00011101. Q3. Assume the system has a 16-Byte direct mapped unified L1 cache with a block size of 2 Bytes. The following table shows how the cache looks like after the first access to the memory is finished. Please show; in the provided table, how it looks like after the 20th access is finished. You could ignore the "Data" Column. (Add or remove Rows/Columns in the provided table for your answer, as you see fit). Cache contents after the 1st access: Cache Index…Assume you are given an array of four 16-bit numbers stored in memory with a starting address x3110. Using PC- relative addressing, write an LC-3 machine language program that will copy the same four 16-bit numbers in reverse order, starting at memory address x3120. For example, if the following are the four 16-bit values stored in x3110, x3110 12 x3111 23 х3112 34 х3113 45 then the result of your program execution should write the following starting at memory address x3120: x3120 45 х3121 34 x3122 23 x3123 12 Load your program starting at address x3100. You will need to demonstrate the correct execution of your program by using the LC-3 Simulator.
- Create a program in C++ which simulates a direct cache. The memory array that contains the data to becached is byte addressable and can contain 256 single byte entries or lines. The cache has only 8 entriesor lines. The Data field in each line of the cache is 8 bits. Since the data stored in each line of the cache isonly 8 bits, there is no need for a line field. Only a tag field is needed which is log2(256) = 8 bits.The memory array can be filled with any values of your choice. The program should work by taking userinput of a memory address (index). This input represents the memory data that should be cached.Check the cache to see if the item is already cached. If it is not, your program should counta cache miss, and then replace the item currently in the cache with the data from the inputted address.Allow the user to input addresses (in a loop), until they so choose to end the program. The program should output the number of cache misses upon ending.Write a code in sim8085 for the following problem: The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the ‘D’ register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register ‘D’. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78, 65, 89, 56, 752. Implement the frame replacement algorithm for virtual memory In Java For this task, you need to perform the simulation of page replacement algorithms. Create a Java program which allows the user to specify: • the total of frames currently exist in memory (F), the total of page requests (N) to be processed, • the list or sequence of N page requests involved, For example, if N is 10, user must input a list of 10 values (ranging between 0 to TP-1) as the request sequence. Optionally you may also get additional input, the total of pages (TP) This input is optional for your program/work. It only be used to verify that each of the page number given in the request list is valid or invalid. Valid page number should be within the range 0, .. , TP-1. Page number outside the range is invalid. Then use the input data to calculate the number of page faults produced by each of the following page replacement algorithms: • First-in-first-out (FIFO) - the candidate that is the first one that entered…
