Find solution to this question on memory hierarchies in computer structures (Refer to the screenshot); 2)A computer system uses 16-bit memory addresses. It has a 2Kbyte cache organized in adirect-mapped fashion with 64 bytes per cache block. Assume that the size of eachmemory word is 1 byte.a)b)Determine the number of bits in each Tag, Block and Word fields of the memoryaddress.When a program is executed, the CPU reads data sequentially from the followingword addresses:128, 144, 2176, 2180, 128, 2176All the addresses are shown in decimal values. Assume that the cache is initiallyempty. For each of the six addresses, indicate whether the cache access will resultin a hit or miss. Show all work.Calculate the hit rate, showing all work.

A.) Block Offset: This is determined by the size of the cache block. Each block in the cache is 64…

(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
A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.
(Practice) a. Using Figure 2.14 and assuming the variable name rate is assigned to the byte at memory address 159, determine the addresses corresponding to each variable declared in the following statements. Also, fill in the correct number of bytes with the initialization data included in the declaration statements. (Use letters for the characters, not the computer codes that would actually be stored.) floatrate; charch1=M,ch2=E,ch3=L,ch4=T; doubletaxes; intnum,count=0; b. Repeat Exercise 9a, but substitute the actual byte patterns that a computer using the ASCII code would use to store characters in the variables ch1, ch2, ch3, and ch4. (Hint: Use Appendix B.)
What primitive data types can normally be represented and processed by a CPU?
(Practice) Write a C++ program that adds equivalent elements of the two-dimensional arrays named first and second. Both arrays should have two rows and three columns. For example, element [1][2] of the resulting array should be the sum of first [1][2]andsecond[1][2]. The first and second arrays should be initialized as follows: first second 16 18 23 24 52 77 54 9111 16 19 59
