**Cache Memory Addressing: Understanding the Main Memory Address Format****Problem Statement:**A 2-way set-associative cache consists of four sets. The main memory contains 2K blocks of 8 bytes each, and byte addressing is used.1. **Task**: Show the main memory address format that allows us to map addresses from main memory to cache. Be sure to include the fields as well as their sizes.**Explanation:**In this scenario, we need to understand how the main memory address is structured to efficiently map into the cache. - **2-Way Set-Associative Cache**: This means each set in the cache can store two blocks of data.- **Cache Structure**: With four sets, it can be visualized as a table with four rows (sets) where each row has two slots (ways) for data blocks.- **Main Memory**: Contains 2K blocks of 8 bytes each, indicating we need to address 2048 blocks. **Address Format:**- **Block Offset**: Determines the specific byte within a block (3 bits are needed because 2^3 = 8).- **Set Index**: Identifies the cache set a block will map to. With four sets, 2 bits (2^2 = 4) are needed.- **Tag**: The remaining bits are used for the tag, which uniquely identifies a block in the cache when combined with the set index.**Fields and Sizes:**- **Block Offset**: 3 bits- **Set Index**: 2 bits- **Tag**: Remaining bits from the total memory address width. This structure helps in efficiently mapping and accessing the main memory data through the cache while avoiding collisions and optimizing performance.

Fill in blank Suppose that segmentation technique is used for memory management. If the memory addresses are 7-bit binary numbers where the first two bits are used to specify segment ID, then the size of a user stack will be ---------- bytes.
9. “The reason of having cache in a system is because a program tends to have Locality of Reference”. Briefly explain the term Locality of Reference with example(s).
Q1). Suppose $s0 stores the base address of word array A and $t0 is associated with m, convert the following instruction into MIPS. A[240] = A[240+m]Q2). Suppose $t0 stores the base address of word array A and $s0 is associated with m, convert the following instruction into MIPS. m= 0 while (m <= 10): A[m] = A[m+4]*6 m = m + 5
1. Caches are important to providing a high-performance memory hierarchy to processors. Below is a list of 32-bit memory address references, given as word addresses. 42, 137, 66, 50, 38, 225, 173, 22, 19, 88, 51, 43 a. For each of these references, identify the binary address, the tag, and the index given a direct mapped cache with 16 one-word blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. b. For each of these references, identify the binary address, the tag, and the index given a direct mapped cache with two-word blocks and a total size of 8 blocks. Also list if each reference is a hit or a miss, assuming the cache is initially empty. Please explain the process.
Using C Language In this function, b has the address of a memory buffer that is num_bytes long. The function should repeatedly copy the 16 byte pattern that pattern16 points at into the memory buffer until num_bytes have been written. If num_bytes is not a multple of 16, the final write of the 16 byte pattern should be truncated to finish filling the buffer. void memset16(void *b, int num_bytes, void *pattern16) For example if the 16 bytes that pattern16 points at is 00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff, then memset(b, 20, pattern16) should write to the buffer pointed at by p the 20 bytes 00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff 00 11 22 33. Use SSE instructions to improve efficiency. Here's pseudocode. x = SSE unaligned load from pattern16while (num_bytes >= 16) SSE unaligned store x to p advance p by 16 bytes decrement num_bytes by 16while (num_bytes > 0) store 1 byte from pattern16 to p advance p by 1 byte advance pattern16 by 1 byte…

1. Suppose an array with six rows and eight columns is stored in a row major order starting at address 20 (base 10). If each entry in the array requires only one memory cell, what is the address on the entry in the third row and fourth columns? What if each entry requires two memory cells?
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(); }
1- Write a MIPS assembly program that stores the values in consecutive successive words in the data segment with the initial offset 3000A, ending at offset 3FFEB. Then store the value 3000F to location 1000F. Next, write a code segment that sums the 128 words starting at the address found in location 1000F. This portion of the program cannot assume that 1000B contains 3000A. Print the sum and then quit. 2- Write a MIPS program that access an array of words starting at address 1000F and memory, of the length specified by the value in cx, and searches the maximum value in the array. Print the value after finding an element. 3- Write a MIPS assembly language program to reverse the numbers for two dimensional array of size 4X4

5. A computer has an L1 and L2 cache, backed up by DRAM which is backed up by virtual memory. The TLB and L1 caches have hit times of .5 ns. The TLB's backup is the page table in DRAM while L1 cache's backup is an L2 cache. The L2 cache has a hit time of 1.5 ns. DRAM has a hit time of 10 ns. Swap space has a hit time of 2,500,000 ns. The hit rates are: TLB: 98.8%, L1: 91.5%, L2: 97.7%, DRAM: 99.9998% and swap space 100%. What is the effective access time?
