Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

14.3 There exists processor with 16-bit word length (8-bit addressing unit) with a memory size of 32k words. The addressing method is register - based and direct. Instructions are encoded in two types: single-word and two-word with 3 addresses. Assuming there are no more than 576 -25- different instructions, what is the maximum possible number of general purpose registers in this processor?

Note: In single-word instructions all three operands are registers

9.18 A certain computer provides its users with a virtual-memory space of 232 bytes. The computer has 218 bytes of physical memory. The virtual memory is implemented by paging, and the page size is 4096 bytes. How many pages are possible in the system? How many frames can it have?
(Practice) Although the total number of bytes varies from computer to computer, memory sizes of millions and billions of bytes are common. In computer language, the letter M representsthe number 1,048,576, which is 2 raised to the 20th power, and G represents 1,073,741,824, which is 2 raised to the 30th power. Therefore, a memory size of 4 MB is really 4 times 1,048,576 (4,194,304 bytes), and a memory size of 2 GB is really 2 times 1,073,741,824 (2,147,483,648 bytes). Using this information, calculate the actual number of bytes in the following: a. A memory containing 512 MB b. A memory consisting of 512 MB words, where each word consists of 2 bytes c. A memory consisting of 512 MB words, where each word consists of 4 bytes d. A thumb drive that specifies 2 GB e. A disk that specifies 4 GB f. A disk that specifies 8 GB
c) To illustrate what difference a vector processor can make as compared to a traditional CPU, consider a hypothetical RISC machine with these lines of code ; Hypothetical RISC machine; add 10 numbers in a to 10 numbers in b, storing results in c; assume a, b, and c are memory locations in their respective registers move $10, count ; count := 10 loop: load r1, aload r2, badd r3,r1,r2 ;r3:=r1+r2store r3, cadd a,a,$4 ;moveonadd b,b,$4add c,c,$4dec count ; decrementjnez count, loop ; loop back if count is not yet 0 ret How would a Cray-style vector machine process this information? d.) State three advantages in the vector style approach
Consider the following image that represents part of the memory of a 16-bit address space that has an addressability of 2 bytes (like LC-3): A memory location can store an address. We call that memory location's contents a "pointer" since it's an address that "points" to another memory location. G.) Interpret the contents at address 0x0C0B as a pointer. (Enter hex like the following example: 0x2A3F) H.) What are the contents of the memory location that the pointer above is pointing to? (Enter hex like the following example: 0x2A3F) Another reference : LC-3 Opcodes in Hex ADD 0x1 JMP 0xC LDR 0x6
) Consider the following sequence of virtual memory references (in decimal) generatedby a single program in a pure paging system:100, 110, 1400, 1700, 703, 3090, 1850, 2405, 2460, 4304, 4580, 3640a. Derive the corresponding reference string of pages (i.e. the pages the virtual addressesare located on), assuming a page size of 1024 bytes. (Assume that page numberingstarts at 0)b. For the page sequence derived above, determine the number of page faults for each ofthe following page replacement strategies, assuming that two (2) page frames areavailable to the program.i. LRUii. FIFOiii. OPT (Optimal)
Answer the given question with a proper explanation and step-by-step solution. 1. Consider the following code fragment. (a) Draw the pictorial representation of the memory, starting from the first line of code and ending with the last line of code (all in one picture so I can see the changes). (b) This code has a problem. What is it? How is it called? double x = 1.5, y = 3.4; double* p = &x; double* p2 = new double[12]; *p += y; p = &y; *p *= 2; for (int i{0}; i < 12; ++i) { p2[i] = 1.6; } p2 = p; delete p2;
Generate a listing file for AddTwoSum.asm(in 3.4.3 of the text) and write a description of the machine code bytes generated for each instruction.

Assume we have a free space management system as described in the book, for example one used to provide us with virtual addresses on the heap (with physical addresses handled by a much simpler system since we assume paging). Assume the system uses the following very simple rules; A memory request traverses the free list, and finds the first block large enough to handle the request (i.e., the first fit algorithm from the book). It then: Splits the block into 2 pieces: The first piece will be the requested size + 1k (for a header). The second will be the remaining The first piece will be returned to the caller, but the address returned will be the address of the memory for the user, that is the header + 1k The second will be put back into the linked list If there's insufficient contiguous memory, the allocation will fail (return 0) Free memory is stored as a linked list in address order Assume we start with a single contiguous block of FREE memory of size 64k starting at location…
CA_10 Let the virtual address be V bits and the virtual addtess space be byte-addressable, the page size be P KB (and P is a power of 2), and the the main memory size be MM MB(where [MM MB]) is divide into [P KB]). (d)How many of the virtual memory bits need to be translated? (e) How many bits will be produced if the virtual-to-pyysical address translation is "successful" (f) How many bits does a physical address have, and how are each of these bits obtained?
Q3) b There are two implementations; computer “A” with 1.75 GHz processor and 512 MB of RAM, while the processor speed of computer “B” is two times faster than A, i.e. 3.5GHz and similarly 1 GB of RAM. There is program with 10 instruction runs on A in 20ns while in the same period of time the another program with 20 instructions runs on B. Determine the CPUs performance and decide which one is faster.
Let's say that p is a pointer to memory and the next four bytes in memory (in hex) beginning at p's address are: 89 AB CD EF. After the following code is run on a little-endian computer what are the values of x, y, and the four bytes in memory beginning at p's address. Answer for x and y in four digits of upper-case hexadecimal (eg, 0AC6). Answer for memory as eight digits of upper-case hexadecimal with a single space between each byte (eg, 89 AB CD EF). x: y: mem at p:
CODE IN JAVA !!!!!!!!!!!!!!!!!!!!!!! Provide a code for LRU The Last Recently Used (LRU) solution for the memory page replacement but using two bits (boolean variable in Java) for the clock algorithm with one indicates the reference bit and the other indicates the read/write bit. Here we assume for all the processes, the pages with the number 2 and 5 involve data writing operation; all the other numbers (1, 3, 4, 6) only involve reading operations. Provide output examples of the code at the bottom.
